function\n\t *\n\t * @description\n\t * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.\n\t *\n\t * If jQuery is available, `angular.element` is an alias for the\n\t * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`\n\t * delegates to Angular's built-in subset of jQuery, called \"jQuery lite\" or **jqLite**.\n\t *\n\t * jqLite is a tiny, API-compatible subset of jQuery that allows\n\t * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most\n\t * commonly needed functionality with the goal of having a very small footprint.\n\t *\n\t * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the\n\t * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a\n\t * specific version of jQuery if multiple versions exist on the page.\n\t *\n\t *
**Note:** All element references in Angular are always wrapped with jQuery or\n\t * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
\n\t *\n\t *
**Note:** Keep in mind that this function will not find elements\n\t * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`\n\t * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
\n\t *\n\t * ## Angular's jqLite\n\t * jqLite provides only the following jQuery methods:\n\t *\n\t * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument\n\t * - [`after()`](http://api.jquery.com/after/)\n\t * - [`append()`](http://api.jquery.com/append/)\n\t * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n\t * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData\n\t * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n\t * - [`clone()`](http://api.jquery.com/clone/)\n\t * - [`contents()`](http://api.jquery.com/contents/)\n\t * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.\n\t * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.\n\t * - [`data()`](http://api.jquery.com/data/)\n\t * - [`detach()`](http://api.jquery.com/detach/)\n\t * - [`empty()`](http://api.jquery.com/empty/)\n\t * - [`eq()`](http://api.jquery.com/eq/)\n\t * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n\t * - [`hasClass()`](http://api.jquery.com/hasClass/)\n\t * - [`html()`](http://api.jquery.com/html/)\n\t * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n\t * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n\t * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter\n\t * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n\t * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n\t * - [`prepend()`](http://api.jquery.com/prepend/)\n\t * - [`prop()`](http://api.jquery.com/prop/)\n\t * - [`ready()`](http://api.jquery.com/ready/)\n\t * - [`remove()`](http://api.jquery.com/remove/)\n\t * - [`removeAttr()`](http://api.jquery.com/removeAttr/)\n\t * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument\n\t * - [`removeData()`](http://api.jquery.com/removeData/)\n\t * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n\t * - [`text()`](http://api.jquery.com/text/)\n\t * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument\n\t * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers\n\t * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter\n\t * - [`val()`](http://api.jquery.com/val/)\n\t * - [`wrap()`](http://api.jquery.com/wrap/)\n\t *\n\t * ## jQuery/jqLite Extras\n\t * Angular also provides the following additional methods and events to both jQuery and jqLite:\n\t *\n\t * ### Events\n\t * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n\t * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n\t * element before it is removed.\n\t *\n\t * ### Methods\n\t * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n\t * retrieves controller associated with the `ngController` directive. If `name` is provided as\n\t * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n\t * `'ngModel'`).\n\t * - `injector()` - retrieves the injector of the current element or its parent.\n\t * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n\t * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to\n\t * be enabled.\n\t * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n\t * current element. This getter should be used only on elements that contain a directive which starts a new isolate\n\t * scope. Calling `scope()` on this element always returns the original non-isolate scope.\n\t * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.\n\t * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n\t * parent element is reached.\n\t *\n\t * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See\n\t * https://github.com/angular/angular.js/issues/14251 for more information.\n\t *\n\t * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n\t * @returns {Object} jQuery object.\n\t */\n\t\n\tJQLite.expando = 'ng339';\n\t\n\tvar jqCache = JQLite.cache = {},\n\t jqId = 1,\n\t addEventListenerFn = function(element, type, fn) {\n\t element.addEventListener(type, fn, false);\n\t },\n\t removeEventListenerFn = function(element, type, fn) {\n\t element.removeEventListener(type, fn, false);\n\t };\n\t\n\t/*\n\t * !!!

\n\t * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from\n\t * the top of the page to the element's bottom will be used as offset.
\n\t * **Note**: The element will be taken into account only as long as its `position` is set to\n\t * `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust\n\t * their height and/or positioning according to the viewport's size.\n\t *\n\t *

\n\t * **Note:** This document is an in-depth reference of all directive options.\n\t * For a gentle introduction to directives with examples of common use cases,\n\t * see the {@link guide/directive directive guide}.\n\t *
\n\t *\n\t * ## Comprehensive Directive API\n\t *\n\t * There are many different options for a directive.\n\t *\n\t * The difference resides in the return value of the factory function.\n\t * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}\n\t * that defines the directive properties, or just the `postLink` function (all other properties will have\n\t * the default values).\n\t *\n\t *
\n\t * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n\t *
\n\t *\n\t * Here's an example directive declared with a Directive Definition Object:\n\t *\n\t * ```js\n\t * var myModule = angular.module(...);\n\t *\n\t * myModule.directive('directiveName', function factory(injectables) {\n\t * var directiveDefinitionObject = {\n\t * priority: 0,\n\t * template: '
', // or // function(tElement, tAttrs) { ... },\n\t * // or\n\t * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },\n\t * transclude: false,\n\t * restrict: 'A',\n\t * templateNamespace: 'html',\n\t * scope: false,\n\t * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n\t * controllerAs: 'stringIdentifier',\n\t * bindToController: false,\n\t * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n\t * compile: function compile(tElement, tAttrs, transclude) {\n\t * return {\n\t * pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n\t * post: function postLink(scope, iElement, iAttrs, controller) { ... }\n\t * }\n\t * // or\n\t * // return function postLink( ... ) { ... }\n\t * },\n\t * // or\n\t * // link: {\n\t * // pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n\t * // post: function postLink(scope, iElement, iAttrs, controller) { ... }\n\t * // }\n\t * // or\n\t * // link: function postLink( ... ) { ... }\n\t * };\n\t * return directiveDefinitionObject;\n\t * });\n\t * ```\n\t *\n\t *
\n\t * **Note:** Any unspecified options will use the default value. You can see the default values below.\n\t *
\n\t *\n\t * Therefore the above can be simplified as:\n\t *\n\t * ```js\n\t * var myModule = angular.module(...);\n\t *\n\t * myModule.directive('directiveName', function factory(injectables) {\n\t * var directiveDefinitionObject = {\n\t * link: function postLink(scope, iElement, iAttrs) { ... }\n\t * };\n\t * return directiveDefinitionObject;\n\t * // or\n\t * // return function postLink(scope, iElement, iAttrs) { ... }\n\t * });\n\t * ```\n\t *\n\t * ### Life-cycle hooks\n\t * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the\n\t * directive:\n\t * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and\n\t * had their bindings initialized (and before the pre & post linking functions for the directives on\n\t * this element). This is a good place to put initialization code for your controller.\n\t * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The\n\t * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an\n\t * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a\n\t * component such as cloning the bound value to prevent accidental mutation of the outer value.\n\t * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on\n\t * changes. Any actions that you wish to take in response to the changes that you detect must be\n\t * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook\n\t * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not\n\t * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;\n\t * if detecting changes, you must store the previous value(s) for comparison to the current values.\n\t * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing\n\t * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in\n\t * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent\n\t * components will have their `$onDestroy()` hook called before child components.\n\t * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link\n\t * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.\n\t * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since\n\t * they are waiting for their template to load asynchronously and their own compilation and linking has been\n\t * suspended until that occurs.\n\t *\n\t * #### Comparison with Angular 2 life-cycle hooks\n\t * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are\n\t * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:\n\t *\n\t * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.\n\t * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.\n\t * In Angular 2 you can only define hooks on the prototype of the Component class.\n\t * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to\n\t * `ngDoCheck` in Angular 2\n\t * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be\n\t * propagated throughout the application.\n\t * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an\n\t * error or do nothing depending upon the state of `enableProdMode()`.\n\t *\n\t * #### Life-cycle hook examples\n\t *\n\t * This example shows how you can check for mutations to a Date object even though the identity of the object\n\t * has not changed.\n\t *\n\t * \n\t * \n\t * angular.module('do-check-module', [])\n\t * .component('app', {\n\t * template:\n\t * 'Month: ' +\n\t * 'Date: {{ $ctrl.date }}' +\n\t * '',\n\t * controller: function() {\n\t * this.date = new Date();\n\t * this.month = this.date.getMonth();\n\t * this.updateDate = function() {\n\t * this.date.setMonth(this.month);\n\t * };\n\t * }\n\t * })\n\t * .component('test', {\n\t * bindings: { date: '<' },\n\t * template:\n\t * '
{{ $ctrl.log | json }}
',\n\t * controller: function() {\n\t * var previousValue;\n\t * this.log = [];\n\t * this.$doCheck = function() {\n\t * var currentValue = this.date && this.date.valueOf();\n\t * if (previousValue !== currentValue) {\n\t * this.log.push('doCheck: date mutated: ' + this.date);\n\t * previousValue = currentValue;\n\t * }\n\t * };\n\t * }\n\t * });\n\t * \n\t * \n\t * \n\t * \n\t * \n\t *\n\t * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the\n\t * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large\n\t * arrays or objects can have a negative impact on your application performance)\n\t *\n\t * \n\t * \n\t *

The attributes are:\n\t *\n\t * #### `multiElement`\n\t * When this property is set to true, the HTML compiler will collect DOM nodes between\n\t * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n\t * together as the directive elements. It is recommended that this feature be used on directives\n\t * which are not strictly behavioral (such as {@link ngClick}), and which\n\t * do not manipulate or replace child nodes (such as {@link ngInclude}).\n\t *\n\t * #### `priority`\n\t * When there are multiple directives defined on a single DOM element, sometimes it\n\t * is necessary to specify the order in which the directives are applied. The `priority` is used\n\t * to sort the directives before their `compile` functions get called. Priority is defined as a\n\t * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n\t * are also run in priority order, but post-link functions are run in reverse order. The order\n\t * of directives with the same priority is undefined. The default priority is `0`.\n\t *\n\t * #### `terminal`\n\t * If set to true then the current `priority` will be the last set of directives\n\t * which will execute (any directives at the current priority will still execute\n\t * as the order of execution on same `priority` is undefined). Note that expressions\n\t * and other directives used in the directive's template will also be excluded from execution.\n\t *\n\t * #### `scope`\n\t * The scope property can be `true`, an object or a falsy value:\n\t *\n\t * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.\n\t *\n\t * * **`true`:** A new child scope that prototypically inherits from its parent will be created for\n\t * the directive's element. If multiple directives on the same element request a new scope,\n\t * only one new scope is created. The new scope rule does not apply for the root of the template\n\t * since the root of the template always gets a new scope.\n\t *\n\t * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's element. The\n\t * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent\n\t * scope. This is useful when creating reusable components, which should not accidentally read or modify\n\t * data in the parent scope.\n\t *\n\t * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the\n\t * directive's element. These local properties are useful for aliasing values for templates. The keys in\n\t * the object hash map to the name of the property on the isolate scope; the values define how the property\n\t * is bound to the parent scope, via matching attributes on the directive's element:\n\t *\n\t * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n\t * always a string since DOM attributes are strings. If no `attr` name is specified then the\n\t * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,\n\t * the directive's scope property `localName` will reflect the interpolated value of `hello\n\t * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's\n\t * scope. The `name` is read from the parent scope (not the directive's scope).\n\t *\n\t * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression\n\t * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.\n\t * If no `attr` name is specified then the attribute name is assumed to be the same as the local\n\t * name. Given `` and the isolate scope definition `scope: {\n\t * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the\n\t * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in\n\t * `localModel` and vice versa. Optional attributes should be marked as such with a question mark:\n\t * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't\n\t * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})\n\t * will be thrown upon discovering changes to the local value, since it will be impossible to sync\n\t * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}\n\t * method is used for tracking changes, and the equality check is based on object identity.\n\t * However, if an object literal or an array literal is passed as the binding expression, the\n\t * equality check is done by value (using the {@link angular.equals} function). It's also possible\n\t * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection\n\t * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).\n\t *\n\t * * `<` or `` and directive definition of\n\t * `scope: { localModel:'` and the isolate scope definition `scope: {\n\t * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for\n\t * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope\n\t * via an expression to the parent scope. This can be done by passing a map of local variable names\n\t * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`\n\t * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.\n\t *\n\t * In general it's possible to apply more than one directive to one element, but there might be limitations\n\t * depending on the type of scope required by the directives. The following points will help explain these limitations.\n\t * For simplicity only two directives are taken into account, but it is also applicable for several directives:\n\t *\n\t * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope\n\t * * **child scope** + **no scope** => Both directives will share one single child scope\n\t * * **child scope** + **child scope** => Both directives will share one single child scope\n\t * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use\n\t * its parent's scope\n\t * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot\n\t * be applied to the same element.\n\t * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives\n\t * cannot be applied to the same element.\n\t *\n\t *\n\t * #### `bindToController`\n\t * This property is used to bind scope properties directly to the controller. It can be either\n\t * `true` or an object hash with the same format as the `scope` property. Additionally, a controller\n\t * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller\n\t * definition: `controller: 'myCtrl as myAlias'`.\n\t *\n\t * When an isolate scope is used for a directive (see above), `bindToController: true` will\n\t * allow a component to have its properties bound to the controller, rather than to scope.\n\t *\n\t * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller\n\t * properties. You can access these bindings once they have been initialized by providing a controller method called\n\t * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings\n\t * initialized.\n\t *\n\t *
\n\t * **Deprecation warning:** although bindings for non-ES6 class controllers are currently\n\t * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization\n\t * code that relies upon bindings inside a `$onInit` method on the controller, instead.\n\t *
\n\t *\n\t * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.\n\t * This will set up the scope bindings to the controller directly. Note that `scope` can still be used\n\t * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate\n\t * scope (useful for component directives).\n\t *\n\t * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.\n\t *\n\t *\n\t * #### `controller`\n\t * Controller constructor function. The controller is instantiated before the\n\t * pre-linking phase and can be accessed by other directives (see\n\t * `require` attribute). This allows the directives to communicate with each other and augment\n\t * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n\t *\n\t * * `$scope` - Current scope associated with the element\n\t * * `$element` - Current element\n\t * * `$attrs` - Current attributes object for the element\n\t * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n\t * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:\n\t * * `scope`: (optional) override the scope.\n\t * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.\n\t * * `futureParentElement` (optional):\n\t * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n\t * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n\t * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n\t * and when the `cloneLinkinFn` is passed,\n\t * as those elements need to created and cloned in a special way when they are defined outside their\n\t * usual containers (e.g. like ``).\n\t * * See also the `directive.templateNamespace` property.\n\t * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)\n\t * then the default translusion is provided.\n\t * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns\n\t * `true` if the specified slot contains content (i.e. one or more DOM nodes).\n\t *\n\t * #### `require`\n\t * Require another directive and inject its controller as the fourth argument to the linking function. The\n\t * `require` property can be a string, an array or an object:\n\t * * a **string** containing the name of the directive to pass to the linking function\n\t * * an **array** containing the names of directives to pass to the linking function. The argument passed to the\n\t * linking function will be an array of controllers in the same order as the names in the `require` property\n\t * * an **object** whose property values are the names of the directives to pass to the linking function. The argument\n\t * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding\n\t * controllers.\n\t *\n\t * If the `require` property is an object and `bindToController` is truthy, then the required controllers are\n\t * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers\n\t * have been constructed but before `$onInit` is called.\n\t * If the name of the required controller is the same as the local name (the key), the name can be\n\t * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.\n\t * See the {@link $compileProvider#component} helper for an example of how this can be used.\n\t * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is\n\t * raised (unless no link function is specified and the required controllers are not being bound to the directive\n\t * controller, in which case error checking is skipped). The name can be prefixed with:\n\t *\n\t * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.\n\t * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.\n\t * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.\n\t * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.\n\t * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass\n\t * `null` to the `link` fn if not found.\n\t * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass\n\t * `null` to the `link` fn if not found.\n\t *\n\t *\n\t * #### `controllerAs`\n\t * Identifier name for a reference to the controller in the directive's scope.\n\t * This allows the controller to be referenced from the directive template. This is especially\n\t * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible\n\t * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the\n\t * `controllerAs` reference might overwrite a property that already exists on the parent scope.\n\t *\n\t *\n\t * #### `restrict`\n\t * String of subset of `EACM` which restricts the directive to a specific directive\n\t * declaration style. If omitted, the defaults (elements and attributes) are used.\n\t *\n\t * * `E` - Element name (default): ``\n\t * * `A` - Attribute (default): `
`\n\t * * `C` - Class: `
`\n\t * * `M` - Comment: ``\n\t *\n\t *\n\t * #### `templateNamespace`\n\t * String representing the document type used by the markup in the template.\n\t * AngularJS needs this information as those elements need to be created and cloned\n\t * in a special way when they are defined outside their usual containers like `` and ``.\n\t *\n\t * * `html` - All root nodes in the template are HTML. Root nodes may also be\n\t * top-level elements such as `` or ``.\n\t * * `svg` - The root nodes in the template are SVG elements (excluding ``).\n\t * * `math` - The root nodes in the template are MathML elements (excluding ``).\n\t *\n\t * If no `templateNamespace` is specified, then the namespace is considered to be `html`.\n\t *\n\t * #### `template`\n\t * HTML markup that may:\n\t * * Replace the contents of the directive's element (default).\n\t * * Replace the directive's element itself (if `replace` is true - DEPRECATED).\n\t * * Wrap the contents of the directive's element (if `transclude` is true).\n\t *\n\t * Value may be:\n\t *\n\t * * A string. For example `
{{delete_str}}
`.\n\t * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n\t * function api below) and returns a string value.\n\t *\n\t *\n\t * #### `templateUrl`\n\t * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n\t *\n\t * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n\t * for later when the template has been resolved. In the meantime it will continue to compile and link\n\t * sibling and parent elements as though this element had not contained any directives.\n\t *\n\t * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n\t * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n\t * case when only one deeply nested directive has `templateUrl`.\n\t *\n\t * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}\n\t *\n\t * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n\t * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n\t * a string value representing the url. In either case, the template URL is passed through {@link\n\t * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n\t *\n\t *\n\t * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)\n\t * specify what the template should replace. Defaults to `false`.\n\t *\n\t * * `true` - the template will replace the directive's element.\n\t * * `false` - the template will replace the contents of the directive's element.\n\t *\n\t * The replacement process migrates all of the attributes / classes from the old element to the new\n\t * one. See the {@link guide/directive#template-expanding-directive\n\t * Directives Guide} for an example.\n\t *\n\t * There are very few scenarios where element replacement is required for the application function,\n\t * the main one being reusable custom components that are used within SVG contexts\n\t * (because SVG doesn't work with custom elements in the DOM tree).\n\t *\n\t * #### `transclude`\n\t * Extract the contents of the element where the directive appears and make it available to the directive.\n\t * The contents are compiled and provided to the directive as a **transclusion function**. See the\n\t * {@link $compile#transclusion Transclusion} section below.\n\t *\n\t *\n\t * #### `compile`\n\t *\n\t * ```js\n\t * function compile(tElement, tAttrs, transclude) { ... }\n\t * ```\n\t *\n\t * The compile function deals with transforming the template DOM. Since most directives do not do\n\t * template transformation, it is not used often. The compile function takes the following arguments:\n\t *\n\t * * `tElement` - template element - The element where the directive has been declared. It is\n\t * safe to do template transformation on the element and child elements only.\n\t *\n\t * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n\t * between all directive compile functions.\n\t *\n\t * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n\t *\n\t *
\n\t * **Note:** The template instance and the link instance may be different objects if the template has\n\t * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n\t * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n\t * should be done in a linking function rather than in a compile function.\n\t *
\n\t\n\t *
\n\t * **Note:** The compile function cannot handle directives that recursively use themselves in their\n\t * own templates or compile functions. Compiling these directives results in an infinite loop and\n\t * stack overflow errors.\n\t *\n\t * This can be avoided by manually using $compile in the postLink function to imperatively compile\n\t * a directive's template instead of relying on automatic template compilation via `template` or\n\t * `templateUrl` declaration or manual compilation inside the compile function.\n\t *
\n\t *\n\t *
\n\t * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n\t * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n\t * to the link function instead.\n\t *
\n\t\n\t * A compile function can have a return value which can be either a function or an object.\n\t *\n\t * * returning a (post-link) function - is equivalent to registering the linking function via the\n\t * `link` property of the config object when the compile function is empty.\n\t *\n\t * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n\t * control when a linking function should be called during the linking phase. See info about\n\t * pre-linking and post-linking functions below.\n\t *\n\t *\n\t * #### `link`\n\t * This property is used only if the `compile` property is not defined.\n\t *\n\t * ```js\n\t * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n\t * ```\n\t *\n\t * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n\t * executed after the template has been cloned. This is where most of the directive logic will be\n\t * put.\n\t *\n\t * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n\t * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n\t *\n\t * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n\t * manipulate the children of the element only in `postLink` function since the children have\n\t * already been linked.\n\t *\n\t * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n\t * between all directive linking functions.\n\t *\n\t * * `controller` - the directive's required controller instance(s) - Instances are shared\n\t * among all directives, which allows the directives to use the controllers as a communication\n\t * channel. The exact value depends on the directive's `require` property:\n\t * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one\n\t * * `string`: the controller instance\n\t * * `array`: array of controller instances\n\t *\n\t * If a required controller cannot be found, and it is optional, the instance is `null`,\n\t * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.\n\t *\n\t * Note that you can also require the directive's own controller - it will be made available like\n\t * any other controller.\n\t *\n\t * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n\t * This is the same as the `$transclude` parameter of directive controllers,\n\t * see {@link ng.$compile#-controller- the controller section for details}.\n\t * `function([scope], cloneLinkingFn, futureParentElement)`.\n\t *\n\t * #### Pre-linking function\n\t *\n\t * Executed before the child elements are linked. Not safe to do DOM transformation since the\n\t * compiler linking function will fail to locate the correct elements for linking.\n\t *\n\t * #### Post-linking function\n\t *\n\t * Executed after the child elements are linked.\n\t *\n\t * Note that child elements that contain `templateUrl` directives will not have been compiled\n\t * and linked since they are waiting for their template to load asynchronously and their own\n\t * compilation and linking has been suspended until that occurs.\n\t *\n\t * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n\t * for their async templates to be resolved.\n\t *\n\t *\n\t * ### Transclusion\n\t *\n\t * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and\n\t * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n\t * scope from where they were taken.\n\t *\n\t * Transclusion is used (often with {@link ngTransclude}) to insert the\n\t * original contents of a directive's element into a specified place in the template of the directive.\n\t * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n\t * content has access to the properties on the scope from which it was taken, even if the directive\n\t * has isolated scope.\n\t * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n\t *\n\t * This makes it possible for the widget to have private state for its template, while the transcluded\n\t * content has access to its originating scope.\n\t *\n\t *
\n\t * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n\t * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n\t * Testing Transclusion Directives}.\n\t *
\n\t *\n\t * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the\n\t * directive's element, the entire element or multiple parts of the element contents:\n\t *\n\t * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n\t * * `'element'` - transclude the whole of the directive's element including any directives on this\n\t * element that defined at a lower priority than this directive. When used, the `template`\n\t * property is ignored.\n\t * * **`{...}` (an object hash):** - map elements of the content onto transclusion \"slots\" in the template.\n\t *\n\t * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.\n\t *\n\t * This object is a map where the keys are the name of the slot to fill and the value is an element selector\n\t * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)\n\t * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).\n\t *\n\t * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}\n\t *\n\t * If the element selector is prefixed with a `?` then that slot is optional.\n\t *\n\t * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to\n\t * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.\n\t *\n\t * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements\n\t * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call\n\t * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and\n\t * injectable into the directive's controller.\n\t *\n\t *\n\t * #### Transclusion Functions\n\t *\n\t * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n\t * function** to the directive's `link` function and `controller`. This transclusion function is a special\n\t * **linking function** that will return the compiled contents linked to a new transclusion scope.\n\t *\n\t *
\n\t * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n\t * ngTransclude will deal with it for us.\n\t *
\n\t *\n\t * If you want to manually control the insertion and removal of the transcluded content in your directive\n\t * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery\n\t * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n\t *\n\t * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n\t * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n\t * content and the `scope` is the newly created transclusion scope, to which the clone is bound.\n\t *\n\t *
\n\t * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function\n\t * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n\t *
\n\t *\n\t * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n\t * attach function**:\n\t *\n\t * ```js\n\t * var transcludedContent, transclusionScope;\n\t *\n\t * $transclude(function(clone, scope) {\n\t * element.append(clone);\n\t * transcludedContent = clone;\n\t * transclusionScope = scope;\n\t * });\n\t * ```\n\t *\n\t * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n\t * associated transclusion scope:\n\t *\n\t * ```js\n\t * transcludedContent.remove();\n\t * transclusionScope.$destroy();\n\t * ```\n\t *\n\t *
\n\t * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n\t * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),\n\t * then you are also responsible for calling `$destroy` on the transclusion scope.\n\t *
\n\t *\n\t * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n\t * automatically destroy their transcluded clones as necessary so you do not need to worry about this if\n\t * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n\t *\n\t *\n\t * #### Transclusion Scopes\n\t *\n\t * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n\t * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n\t * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n\t * was taken.\n\t *\n\t * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n\t * like this:\n\t *\n\t * ```html\n\t *
\n\t *
\n\t *
\n\t *
\n\t *
\n\t *
\n\t * ```\n\t *\n\t * The `$parent` scope hierarchy will look like this:\n\t *\n\t ```\n\t - $rootScope\n\t - isolate\n\t - transclusion\n\t ```\n\t *\n\t * but the scopes will inherit prototypically from different scopes to their `$parent`.\n\t *\n\t ```\n\t - $rootScope\n\t - transclusion\n\t - isolate\n\t ```\n\t *\n\t *\n\t * ### Attributes\n\t *\n\t * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n\t * `link()` or `compile()` functions. It has a variety of uses.\n\t *\n\t * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:\n\t * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access\n\t * to the attributes.\n\t *\n\t * * *Directive inter-communication:* All directives share the same instance of the attributes\n\t * object which allows the directives to use the attributes object as inter directive\n\t * communication.\n\t *\n\t * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n\t * allowing other directives to read the interpolated value.\n\t *\n\t * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n\t * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n\t * the only way to easily get the actual value because during the linking phase the interpolation\n\t * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n\t *\n\t * ```js\n\t * function linkingFn(scope, elm, attrs, ctrl) {\n\t * // get the attribute value\n\t * console.log(attrs.ngModel);\n\t *\n\t * // change the attribute\n\t * attrs.$set('ngModel', 'new value');\n\t *\n\t * // observe changes to interpolated attribute\n\t * attrs.$observe('ngModel', function(value) {\n\t * console.log('ngModel has changed value to ' + value);\n\t * });\n\t * }\n\t * ```\n\t *\n\t * ## Example\n\t *\n\t *
\n\t * **Note**: Typically directives are registered with `module.directive`. The example below is\n\t * to illustrate how `$compile` works.\n\t *
\n\t *\n\t \n\t \n\t \n\t
\n\t
\n\t
\n\t
\n\t
\n\t \n\t \n\t it('should auto compile', function() {\n\t var textarea = $('textarea');\n\t var output = $('div[compile]');\n\t // The initial state reads 'Hello Angular'.\n\t expect(output.getText()).toBe('Hello Angular');\n\t textarea.clear();\n\t textarea.sendKeys('{{name}}!');\n\t expect(output.getText()).toBe('Angular!');\n\t });\n\t \n\t \n\t\n\t *\n\t *\n\t * @param {string|DOMElement} element Element or HTML string to compile into a template function.\n\t * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.\n\t *\n\t *
\n\t * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it\n\t * e.g. will not use the right outer scope. Please pass the transclude function as a\n\t * `parentBoundTranscludeFn` to the link function instead.\n\t *
\n\t *\n\t * @param {number} maxPriority only apply directives lower than given priority (Only effects the\n\t * root element(s), not their children)\n\t * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template\n\t * (a DOM element/tree) to a scope. Where:\n\t *\n\t * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n\t * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n\t * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n\t * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n\t * called as:
`cloneAttachFn(clonedElement, scope)` where:\n\t *\n\t * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n\t * * `scope` - is the current scope with which the linking function is working with.\n\t *\n\t * * `options` - An optional object hash with linking options. If `options` is provided, then the following\n\t * keys may be used to control linking behavior:\n\t *\n\t * * `parentBoundTranscludeFn` - the transclude function made available to\n\t * directives; if given, it will be passed through to the link functions of\n\t * directives found in `element` during compilation.\n\t * * `transcludeControllers` - an object hash with keys that map controller names\n\t * to a hash with the key `instance`, which maps to the controller instance;\n\t * if given, it will make the controllers available to directives on the compileNode:\n\t * ```\n\t * {\n\t * parent: {\n\t * instance: parentControllerInstance\n\t * }\n\t * }\n\t * ```\n\t * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n\t * the cloned elements; only needed for transcludes that are allowed to contain non html\n\t * elements (e.g. SVG elements). See also the directive.controller property.\n\t *\n\t * Calling the linking function returns the element of the template. It is either the original\n\t * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n\t *\n\t * After linking the view is not updated until after a call to $digest which typically is done by\n\t * Angular automatically.\n\t *\n\t * If you need access to the bound view, there are two ways to do it:\n\t *\n\t * - If you are not asking the linking function to clone the template, create the DOM element(s)\n\t * before you send them to the compiler and keep this reference around.\n\t * ```js\n\t * var element = $compile('

')(scope);\n\t * ```\n\t *\n\t * - if on the other hand, you need the element to be cloned, the view reference from the original\n\t * example would not point to the clone, but rather to the original template that was cloned. In\n\t * this case, you can access the clone via the cloneAttachFn:\n\t * ```js\n\t * var templateElement = angular.element('

While for simple usage patterns this doesn't matter much, for advanced usage\n\t * it is important to familiarize yourself with these APIs and the guarantees they provide.\n\t *\n\t *\n\t * ## General usage\n\t * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —\n\t * that is used to generate an HTTP request and returns a {@link ng.$q promise}.\n\t *\n\t * ```js\n\t * // Simple GET request example:\n\t * $http({\n\t * method: 'GET',\n\t * url: '/someUrl'\n\t * }).then(function successCallback(response) {\n\t * // this callback will be called asynchronously\n\t * // when the response is available\n\t * }, function errorCallback(response) {\n\t * // called asynchronously if an error occurs\n\t * // or server returns response with an error status.\n\t * });\n\t * ```\n\t *\n\t * The response object has these properties:\n\t *\n\t * - **data** – `{string|Object}` – The response body transformed with the transform\n\t * functions.\n\t * - **status** – `{number}` – HTTP status code of the response.\n\t * - **headers** – `{function([headerName])}` – Header getter function.\n\t * - **config** – `{Object}` – The configuration object that was used to generate the request.\n\t * - **statusText** – `{string}` – HTTP status text of the response.\n\t *\n\t * A response status code between 200 and 299 is considered a success status and will result in\n\t * the success callback being called. Any response status code outside of that range is\n\t * considered an error status and will result in the error callback being called.\n\t * Also, status codes less than -1 are normalized to zero. -1 usually means the request was\n\t * aborted, e.g. using a `config.timeout`.\n\t * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning\n\t * that the outcome (success or error) will be determined by the final response status code.\n\t *\n\t *\n\t * ## Shortcut methods\n\t *\n\t * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n\t * request data must be passed in for POST/PUT requests. An optional config can be passed as the\n\t * last argument.\n\t *\n\t * ```js\n\t * $http.get('/someUrl', config).then(successCallback, errorCallback);\n\t * $http.post('/someUrl', data, config).then(successCallback, errorCallback);\n\t * ```\n\t *\n\t * Complete list of shortcut methods:\n\t *\n\t * - {@link ng.$http#get $http.get}\n\t * - {@link ng.$http#head $http.head}\n\t * - {@link ng.$http#post $http.post}\n\t * - {@link ng.$http#put $http.put}\n\t * - {@link ng.$http#delete $http.delete}\n\t * - {@link ng.$http#jsonp $http.jsonp}\n\t * - {@link ng.$http#patch $http.patch}\n\t *\n\t *\n\t * ## Writing Unit Tests that use $http\n\t * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n\t * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n\t * request using trained responses.\n\t *\n\t * ```\n\t * $httpBackend.expectGET(...);\n\t * $http.get(...);\n\t * $httpBackend.flush();\n\t * ```\n\t *\n\t * ## Deprecation Notice\n\t *
\n\t * The `$http` legacy promise methods `success` and `error` have been deprecated.\n\t * Use the standard `then` method instead.\n\t * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to\n\t * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.\n\t *
\n\t *\n\t * ## Setting HTTP Headers\n\t *\n\t * The $http service will automatically add certain HTTP headers to all requests. These defaults\n\t * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n\t * object, which currently contains this default configuration:\n\t *\n\t * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n\t * - `Accept: application/json, text/plain, * / *`\n\t * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n\t * - `Content-Type: application/json`\n\t * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n\t * - `Content-Type: application/json`\n\t *\n\t * To add or overwrite these defaults, simply add or remove a property from these configuration\n\t * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n\t * with the lowercased HTTP method name as the key, e.g.\n\t * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.\n\t *\n\t * The defaults can also be set at runtime via the `$http.defaults` object in the same\n\t * fashion. For example:\n\t *\n\t * ```\n\t * module.run(function($http) {\n\t * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';\n\t * });\n\t * ```\n\t *\n\t * In addition, you can supply a `headers` property in the config object passed when\n\t * calling `$http(config)`, which overrides the defaults without changing them globally.\n\t *\n\t * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n\t * Use the `headers` property, setting the desired header to `undefined`. For example:\n\t *\n\t * ```js\n\t * var req = {\n\t * method: 'POST',\n\t * url: 'http://example.com',\n\t * headers: {\n\t * 'Content-Type': undefined\n\t * },\n\t * data: { test: 'test' }\n\t * }\n\t *\n\t * $http(req).then(function(){...}, function(){...});\n\t * ```\n\t *\n\t * ## Transforming Requests and Responses\n\t *\n\t * Both requests and responses can be transformed using transformation functions: `transformRequest`\n\t * and `transformResponse`. These properties can be a single function that returns\n\t * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n\t * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n\t *\n\t *
\n\t * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.\n\t * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).\n\t * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest\n\t * function will be reflected on the scope and in any templates where the object is data-bound.\n\t * To prevent this, transform functions should have no side-effects.\n\t * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.\n\t *
\n\t *\n\t * ### Default Transformations\n\t *\n\t * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n\t * `defaults.transformResponse` properties. If a request does not provide its own transformations\n\t * then these will be applied.\n\t *\n\t * You can augment or replace the default transformations by modifying these properties by adding to or\n\t * replacing the array.\n\t *\n\t * Angular provides the following default transformations:\n\t *\n\t * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):\n\t *\n\t * - If the `data` property of the request configuration object contains an object, serialize it\n\t * into JSON format.\n\t *\n\t * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):\n\t *\n\t * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n\t * - If JSON response is detected, deserialize it using a JSON parser.\n\t *\n\t *\n\t * ### Overriding the Default Transformations Per Request\n\t *\n\t * If you wish to override the request/response transformations only for a single request then provide\n\t * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n\t * into `$http`.\n\t *\n\t * Note that if you provide these properties on the config object the default transformations will be\n\t * overwritten. If you wish to augment the default transformations then you must include them in your\n\t * local transformation array.\n\t *\n\t * The following code demonstrates adding a new response transformation to be run after the default response\n\t * transformations have been run.\n\t *\n\t * ```js\n\t * function appendTransform(defaults, transform) {\n\t *\n\t * // We can't guarantee that the default transformation is an array\n\t * defaults = angular.isArray(defaults) ? defaults : [defaults];\n\t *\n\t * // Append the new transformation to the defaults\n\t * return defaults.concat(transform);\n\t * }\n\t *\n\t * $http({\n\t * url: '...',\n\t * method: 'GET',\n\t * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n\t * return doTransform(value);\n\t * })\n\t * });\n\t * ```\n\t *\n\t *\n\t * ## Caching\n\t *\n\t * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must\n\t * set the config.cache value or the default cache value to TRUE or to a cache object (created\n\t * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes\n\t * precedence over the default cache value.\n\t *\n\t * In order to:\n\t * * cache all responses - set the default cache value to TRUE or to a cache object\n\t * * cache a specific response - set config.cache value to TRUE or to a cache object\n\t *\n\t * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,\n\t * then the default `$cacheFactory(\"$http\")` object is used.\n\t *\n\t * The default cache value can be set by updating the\n\t * {@link ng.$http#defaults `$http.defaults.cache`} property or the\n\t * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.\n\t *\n\t * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using\n\t * the relevant cache object. The next time the same request is made, the response is returned\n\t * from the cache without sending a request to the server.\n\t *\n\t * Take note that:\n\t *\n\t * * Only GET and JSONP requests are cached.\n\t * * The cache key is the request URL including search parameters; headers are not considered.\n\t * * Cached responses are returned asynchronously, in the same way as responses from the server.\n\t * * If multiple identical requests are made using the same cache, which is not yet populated,\n\t * one request will be made to the server and remaining requests will return the same response.\n\t * * A cache-control header on the response does not affect if or how responses are cached.\n\t *\n\t *\n\t * ## Interceptors\n\t *\n\t * Before you start creating interceptors, be sure to understand the\n\t * {@link ng.$q $q and deferred/promise APIs}.\n\t *\n\t * For purposes of global error handling, authentication, or any kind of synchronous or\n\t * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n\t * able to intercept requests before they are handed to the server and\n\t * responses before they are handed over to the application code that\n\t * initiated these requests. The interceptors leverage the {@link ng.$q\n\t * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n\t *\n\t * The interceptors are service factories that are registered with the `$httpProvider` by\n\t * adding them to the `$httpProvider.interceptors` array. The factory is called and\n\t * injected with dependencies (if specified) and returns the interceptor.\n\t *\n\t * There are two kinds of interceptors (and two kinds of rejection interceptors):\n\t *\n\t * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to\n\t * modify the `config` object or create a new one. The function needs to return the `config`\n\t * object directly, or a promise containing the `config` or a new `config` object.\n\t * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n\t * resolved with a rejection.\n\t * * `response`: interceptors get called with http `response` object. The function is free to\n\t * modify the `response` object or create a new one. The function needs to return the `response`\n\t * object directly, or as a promise containing the `response` or a new `response` object.\n\t * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n\t * resolved with a rejection.\n\t *\n\t *\n\t * ```js\n\t * // register the interceptor as a service\n\t * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n\t * return {\n\t * // optional method\n\t * 'request': function(config) {\n\t * // do something on success\n\t * return config;\n\t * },\n\t *\n\t * // optional method\n\t * 'requestError': function(rejection) {\n\t * // do something on error\n\t * if (canRecover(rejection)) {\n\t * return responseOrNewPromise\n\t * }\n\t * return $q.reject(rejection);\n\t * },\n\t *\n\t *\n\t *\n\t * // optional method\n\t * 'response': function(response) {\n\t * // do something on success\n\t * return response;\n\t * },\n\t *\n\t * // optional method\n\t * 'responseError': function(rejection) {\n\t * // do something on error\n\t * if (canRecover(rejection)) {\n\t * return responseOrNewPromise\n\t * }\n\t * return $q.reject(rejection);\n\t * }\n\t * };\n\t * });\n\t *\n\t * $httpProvider.interceptors.push('myHttpInterceptor');\n\t *\n\t *\n\t * // alternatively, register the interceptor via an anonymous factory\n\t * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n\t * return {\n\t * 'request': function(config) {\n\t * // same as above\n\t * },\n\t *\n\t * 'response': function(response) {\n\t * // same as above\n\t * }\n\t * };\n\t * });\n\t * ```\n\t *\n\t * ## Security Considerations\n\t *\n\t * When designing web applications, consider security threats from:\n\t *\n\t * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n\t * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n\t *\n\t * Both server and the client must cooperate in order to eliminate these threats. Angular comes\n\t * pre-configured with strategies that address these issues, but for this to work backend server\n\t * cooperation is required.\n\t *\n\t * ### JSON Vulnerability Protection\n\t *\n\t * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n\t * allows third party website to turn your JSON resource URL into\n\t * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n\t * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n\t * Angular will automatically strip the prefix before processing it as JSON.\n\t *\n\t * For example if your server needs to return:\n\t * ```js\n\t * ['one','two']\n\t * ```\n\t *\n\t * which is vulnerable to attack, your server can return:\n\t * ```js\n\t * )]}',\n\t * ['one','two']\n\t * ```\n\t *\n\t * Angular will strip the prefix, before processing the JSON.\n\t *\n\t *\n\t * ### Cross Site Request Forgery (XSRF) Protection\n\t *\n\t * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by\n\t * which the attacker can trick an authenticated user into unknowingly executing actions on your\n\t * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the\n\t * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP\n\t * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the\n\t * cookie, your server can be assured that the XHR came from JavaScript running on your domain.\n\t * The header will not be set for cross-domain requests.\n\t *\n\t * To take advantage of this, your server needs to set a token in a JavaScript readable session\n\t * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n\t * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n\t * that only JavaScript running on your domain could have sent the request. The token must be\n\t * unique for each user and must be verifiable by the server (to prevent the JavaScript from\n\t * making up its own tokens). We recommend that the token is a digest of your site's\n\t * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n\t * for added security.\n\t *\n\t * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName\n\t * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,\n\t * or the per-request config object.\n\t *\n\t * In order to prevent collisions in environments where multiple Angular apps share the\n\t * same domain or subdomain, we recommend that each application uses unique cookie name.\n\t *\n\t * @param {object} config Object describing the request to be made and how it should be\n\t * processed. The object has following properties:\n\t *\n\t * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n\t * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.\n\t * - **params** – `{Object.}` – Map of strings or objects which will be serialized\n\t * with the `paramSerializer` and appended as GET parameters.\n\t * - **data** – `{string|Object}` – Data to be sent as the request message data.\n\t * - **headers** – `{Object}` – Map of strings or functions which return strings representing\n\t * HTTP headers to send to the server. If the return value of a function is null, the\n\t * header will not be sent. Functions accept a config object as an argument.\n\t * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.\n\t * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.\n\t * The handler will be called in the context of a `$apply` block.\n\t * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload\n\t * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.\n\t * The handler will be called in the context of a `$apply` block.\n\t * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.\n\t * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.\n\t * - **transformRequest** –\n\t * `{function(data, headersGetter)|Array.}` –\n\t * transform function or an array of such functions. The transform function takes the http\n\t * request body and headers and returns its transformed (typically serialized) version.\n\t * See {@link ng.$http#overriding-the-default-transformations-per-request\n\t * Overriding the Default Transformations}\n\t * - **transformResponse** –\n\t * `{function(data, headersGetter, status)|Array.}` –\n\t * transform function or an array of such functions. The transform function takes the http\n\t * response body, headers and status and returns its transformed (typically deserialized) version.\n\t * See {@link ng.$http#overriding-the-default-transformations-per-request\n\t * Overriding the Default Transformations}\n\t * - **paramSerializer** - `{string|function(Object):string}` - A function used to\n\t * prepare the string representation of request parameters (specified as an object).\n\t * If specified as string, it is interpreted as function registered with the\n\t * {@link $injector $injector}, which means you can create your own serializer\n\t * by registering it as a {@link auto.$provide#service service}.\n\t * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};\n\t * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}\n\t * - **cache** – `{boolean|Object}` – A boolean value or object created with\n\t * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.\n\t * See {@link $http#caching $http Caching} for more information.\n\t * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}\n\t * that should abort the request when resolved.\n\t * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the\n\t * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)\n\t * for more information.\n\t * - **responseType** - `{string}` - see\n\t * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).\n\t *\n\t * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object\n\t * when the request succeeds or fails.\n\t *\n\t *\n\t * @property {Array.} pendingRequests Array of config objects for currently pending\n\t * requests. This is primarily meant to be used for debugging purposes.\n\t *\n\t *\n\t * @example\n\t\n\t\n\t

So, for HTML elements interpolated\n\t * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter\n\t * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,\n\t * this is typically useful only when user-data is used in rendering a template from the server, or\n\t * when otherwise untrusted data is used by a directive.\n\t *\n\t * \n\t * \n\t *

\n\t * \n\t * \n\t *\n\t * @knownIssue\n\t * It is currently not possible for an interpolated expression to contain the interpolation end\n\t * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.\n\t * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.\n\t *\n\t * @knownIssue\n\t * All directives and components must use the standard `{{` `}}` interpolation symbols\n\t * in their templates. If you change the application interpolation symbols the {@link $compile}\n\t * service will attempt to denormalize the standard symbols to the custom symbols.\n\t * The denormalization process is not clever enough to know not to replace instances of the standard\n\t * symbols where they would not normally be treated as interpolation symbols. For example in the following\n\t * code snippet the closing braces of the literal object will get incorrectly denormalized:\n\t *\n\t * ```\n\t *

However, one can obtain the ability to execute arbitrary JS code by\n\t// obtaining a reference to native JS functions such as the Function constructor.\n\t//\n\t// As an example, consider the following Angular expression:\n\t//\n\t// {}.toString.constructor('alert(\"evil JS code\")')\n\t//\n\t// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits\n\t// against the expression language, but not to prevent exploits that were enabled by exposing\n\t// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good\n\t// practice and therefore we are not even trying to protect against interaction with an object\n\t// explicitly exposed in this way.\n\t//\n\t// In general, it is not possible to access a Window object from an angular expression unless a\n\t// window or some DOM object that has a reference to window is published onto a Scope.\n\t// Similarly we prevent invocations of function known to be dangerous, as well as assignments to\n\t// native objects.\n\t//\n\t// See https://docs.angularjs.org/guide/security\n\t\n\t\n\tfunction ensureSafeMemberName(name, fullExpression) {\n\t if (name === \"__defineGetter__\" || name === \"__defineSetter__\"\n\t || name === \"__lookupGetter__\" || name === \"__lookupSetter__\"\n\t || name === \"__proto__\") {\n\t throw $parseMinErr('isecfld',\n\t 'Attempting to access a disallowed field in Angular expressions!

This is similar to the native Promise implementation from ES6,\n\t * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).\n\t *\n\t * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are\n\t * available yet.\n\t *\n\t * It can be used like so:\n\t *\n\t * ```js\n\t * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n\t * // are available in the current lexical scope (they could have been injected or passed in).\n\t *\n\t * function asyncGreet(name) {\n\t * // perform some asynchronous operation, resolve or reject the promise when appropriate.\n\t * return $q(function(resolve, reject) {\n\t * setTimeout(function() {\n\t * if (okToGreet(name)) {\n\t * resolve('Hello, ' + name + '!');\n\t * } else {\n\t * reject('Greeting ' + name + ' is not allowed.');\n\t * }\n\t * }, 1000);\n\t * });\n\t * }\n\t *\n\t * var promise = asyncGreet('Robin Hood');\n\t * promise.then(function(greeting) {\n\t * alert('Success: ' + greeting);\n\t * }, function(reason) {\n\t * alert('Failed: ' + reason);\n\t * });\n\t * ```\n\t *\n\t * Note: progress/notify callbacks are not currently supported via the ES6-style interface.\n\t *\n\t * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.\n\t *\n\t * However, the more traditional CommonJS-style usage is still available, and documented below.\n\t *\n\t * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an\n\t * interface for interacting with an object that represents the result of an action that is\n\t * performed asynchronously, and may or may not be finished at any given point in time.\n\t *\n\t * From the perspective of dealing with error handling, deferred and promise APIs are to\n\t * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.\n\t *\n\t * ```js\n\t * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n\t * // are available in the current lexical scope (they could have been injected or passed in).\n\t *\n\t * function asyncGreet(name) {\n\t * var deferred = $q.defer();\n\t *\n\t * setTimeout(function() {\n\t * deferred.notify('About to greet ' + name + '.');\n\t *\n\t * if (okToGreet(name)) {\n\t * deferred.resolve('Hello, ' + name + '!');\n\t * } else {\n\t * deferred.reject('Greeting ' + name + ' is not allowed.');\n\t * }\n\t * }, 1000);\n\t *\n\t * return deferred.promise;\n\t * }\n\t *\n\t * var promise = asyncGreet('Robin Hood');\n\t * promise.then(function(greeting) {\n\t * alert('Success: ' + greeting);\n\t * }, function(reason) {\n\t * alert('Failed: ' + reason);\n\t * }, function(update) {\n\t * alert('Got notification: ' + update);\n\t * });\n\t * ```\n\t *\n\t * At first it might not be obvious why this extra complexity is worth the trouble. The payoff\n\t * comes in the way of guarantees that promise and deferred APIs make, see\n\t * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.\n\t *\n\t * Additionally the promise api allows for composition that is very hard to do with the\n\t * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n\t * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n\t * section on serial or parallel joining of promises.\n\t *\n\t * # The Deferred API\n\t *\n\t * A new instance of deferred is constructed by calling `$q.defer()`.\n\t *\n\t * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n\t * that can be used for signaling the successful or unsuccessful completion, as well as the status\n\t * of the task.\n\t *\n\t * **Methods**\n\t *\n\t * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n\t * constructed via `$q.reject`, the promise will be rejected instead.\n\t * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n\t * resolving it with a rejection constructed via `$q.reject`.\n\t * - `notify(value)` - provides updates on the status of the promise's execution. This may be called\n\t * multiple times before the promise is either resolved or rejected.\n\t *\n\t * **Properties**\n\t *\n\t * - promise – `{Promise}` – promise object associated with this deferred.\n\t *\n\t *\n\t * # The Promise API\n\t *\n\t * A new promise instance is created when a deferred instance is created and can be retrieved by\n\t * calling `deferred.promise`.\n\t *\n\t * The purpose of the promise object is to allow for interested parties to get access to the result\n\t * of the deferred task when it completes.\n\t *\n\t * **Methods**\n\t *\n\t * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or\n\t * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously\n\t * as soon as the result is available. The callbacks are called with a single argument: the result\n\t * or rejection reason. Additionally, the notify callback may be called zero or more times to\n\t * provide a progress indication, before the promise is resolved or rejected.\n\t *\n\t * This method *returns a new promise* which is resolved or rejected via the return value of the\n\t * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved\n\t * with the value which is resolved in that promise using\n\t * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).\n\t * It also notifies via the return value of the `notifyCallback` method. The promise cannot be\n\t * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback\n\t * arguments are optional.\n\t *\n\t * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`\n\t *\n\t * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,\n\t * but to do so without modifying the final value. This is useful to release resources or do some\n\t * clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n\t * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n\t * more information.\n\t *\n\t * # Chaining promises\n\t *\n\t * Because calling the `then` method of a promise returns a new derived promise, it is easily\n\t * possible to create a chain of promises:\n\t *\n\t * ```js\n\t * promiseB = promiseA.then(function(result) {\n\t * return result + 1;\n\t * });\n\t *\n\t * // promiseB will be resolved immediately after promiseA is resolved and its value\n\t * // will be the result of promiseA incremented by 1\n\t * ```\n\t *\n\t * It is possible to create chains of any length and since a promise can be resolved with another\n\t * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n\t * the promises at any point in the chain. This makes it possible to implement powerful APIs like\n\t * $http's response interceptors.\n\t *\n\t *\n\t * # Differences between Kris Kowal's Q and $q\n\t *\n\t * There are two main differences:\n\t *\n\t * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n\t * mechanism in angular, which means faster propagation of resolution or rejection into your\n\t * models and avoiding unnecessary browser repaints, which would result in flickering UI.\n\t * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n\t * all the important functionality needed for common async tasks.\n\t *\n\t * # Testing\n\t *\n\t * ```js\n\t * it('should simulate promise', inject(function($q, $rootScope) {\n\t * var deferred = $q.defer();\n\t * var promise = deferred.promise;\n\t * var resolvedValue;\n\t *\n\t * promise.then(function(value) { resolvedValue = value; });\n\t * expect(resolvedValue).toBeUndefined();\n\t *\n\t * // Simulate resolving of promise\n\t * deferred.resolve(123);\n\t * // Note that the 'then' function does not get called synchronously.\n\t * // This is because we want the promise API to always be async, whether or not\n\t * // it got called synchronously or asynchronously.\n\t * expect(resolvedValue).toBeUndefined();\n\t *\n\t * // Propagate promise resolution to 'then' functions using $apply().\n\t * $rootScope.$apply();\n\t * expect(resolvedValue).toEqual(123);\n\t * }));\n\t * ```\n\t *\n\t * @param {function(function, function)} resolver Function which is responsible for resolving or\n\t * rejecting the newly created promise.

One example of\n\t * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer\n\t * to these contexts as privileged or SCE contexts.\n\t *\n\t * As of version 1.2, Angular ships with SCE enabled by default.\n\t *\n\t * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow\n\t * one to execute arbitrary javascript by the use of the expression() syntax. Refer\n\t * to learn more about them.\n\t * You can ensure your document is in standards mode and not quirks mode by adding ``\n\t * to the top of your HTML document.\n\t *\n\t * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for\n\t * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.\n\t *\n\t * Here's an example of a binding in a privileged context:\n\t *\n\t * ```\n\t * \n\t *
\n\t * ```\n\t *\n\t * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE\n\t * disabled, this application allows the user to render arbitrary HTML into the DIV.\n\t * In a more realistic example, one may be rendering user comments, blog articles, etc. via\n\t * bindings. (HTML is just one example of a context where rendering user controlled input creates\n\t * security vulnerabilities.)\n\t *\n\t * For the case of HTML, you might use a library, either on the client side, or on the server side,\n\t * to sanitize unsafe HTML before binding to the value and rendering it in the document.\n\t *\n\t * How would you ensure that every place that used these types of bindings was bound to a value that\n\t * was sanitized by your library (or returned as safe for rendering by your server?) How can you\n\t * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some\n\t * properties/fields and forgot to update the binding to the sanitized value?\n\t *\n\t * To be secure by default, you want to ensure that any such bindings are disallowed unless you can\n\t * determine that something explicitly says it's safe to use a value for binding in that\n\t * context. You can then audit your code (a simple grep would do) to ensure that this is only done\n\t * for those values that you can easily tell are safe - because they were received from your server,\n\t * sanitized by your library, etc. You can organize your codebase to help with this - perhaps\n\t * allowing only the files in a specific directory to do this. Ensuring that the internal API\n\t * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.\n\t *\n\t * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}\n\t * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to\n\t * obtain values that will be accepted by SCE / privileged contexts.\n\t *\n\t *\n\t * ## How does it work?\n\t *\n\t * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted\n\t * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link\n\t * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the\n\t * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.\n\t *\n\t * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link\n\t * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly\n\t * simplified):\n\t *\n\t * ```\n\t * var ngBindHtmlDirective = ['$sce', function($sce) {\n\t * return function(scope, element, attr) {\n\t * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {\n\t * element.html(value || '');\n\t * });\n\t * };\n\t * }];\n\t * ```\n\t *\n\t * ## Impact on loading templates\n\t *\n\t * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as\n\t * `templateUrl`'s specified by {@link guide/directive directives}.\n\t *\n\t * By default, Angular only loads templates from the same domain and protocol as the application\n\t * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl\n\t * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or\n\t * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist\n\t * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.\n\t *\n\t * *Please note*:\n\t * The browser's\n\t * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)\n\t * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)\n\t * policy apply in addition to this and may further restrict whether the template is successfully\n\t * loaded. This means that without the right CORS policy, loading templates from a different domain\n\t * won't work on all browsers. Also, loading templates from `file://` URL does not work on some\n\t * browsers.\n\t *\n\t * ## This feels like too much overhead\n\t *\n\t * It's important to remember that SCE only applies to interpolation expressions.\n\t *\n\t * If your expressions are constant literals, they're automatically trusted and you don't need to\n\t * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.\n\t * `
implicitly trusted'\">
`) just works.\n\t *\n\t * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them\n\t * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.\n\t *\n\t * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load\n\t * templates in `ng-include` from your application's domain without having to even know about SCE.\n\t * It blocks loading templates from other domains or loading templates over http from an https\n\t * served document. You can change these by setting your own custom {@link\n\t * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link\n\t * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.\n\t *\n\t * This significantly reduces the overhead. It is far easier to pay the small overhead and have an\n\t * application that's secure and can be audited to verify that with much more ease than bolting\n\t * security onto an application later.\n\t *\n\t * \n\t * ## What trusted context types are supported?\n\t *\n\t * | Context | Notes |\n\t * |---------------------|----------------|\n\t * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |\n\t * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |\n\t * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |\n\t * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |\n\t *\n\t * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} \n\t *\n\t * Each element in these arrays must be one of the following:\n\t *\n\t * - **'self'**\n\t * - The special **string**, `'self'`, can be used to match against all URLs of the **same\n\t * domain** as the application document using the **same protocol**.\n\t * - **String** (except the special value `'self'`)\n\t * - The string is matched against the full *normalized / absolute URL* of the resource\n\t * being tested (substring matches are not good enough.)\n\t * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters\n\t * match themselves.\n\t * - `*`: matches zero or more occurrences of any character other than one of the following 6\n\t * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use\n\t * in a whitelist.\n\t * - `**`: matches zero or more occurrences of *any* character. As such, it's not\n\t * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.\n\t * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might\n\t * not have been the intention.) Its usage at the very end of the path is ok. (e.g.\n\t * http://foo.example.com/templates/**).\n\t * - **RegExp** (*see caveat below*)\n\t * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax\n\t * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to\n\t * accidentally introduce a bug when one updates a complex expression (imho, all regexes should\n\t * have good test coverage). For instance, the use of `.` in the regex is correct only in a\n\t * small number of cases. A `.` character in the regex used when matching the scheme or a\n\t * subdomain could be matched against a `:` or literal `.` that was likely not intended. It\n\t * is highly recommended to use the string patterns and only fall back to regular expressions\n\t * as a last resort.\n\t * - The regular expression must be an instance of RegExp (i.e. not a string.) It is\n\t * matched against the **entire** *normalized / absolute URL* of the resource being tested\n\t * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags\n\t * present on the RegExp (such as multiline, global, ignoreCase) are ignored.\n\t * - If you are generating your JavaScript from some other templating engine (not\n\t * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),\n\t * remember to escape your regular expression (and be aware that you might need more than\n\t * one level of escaping depending on your templating engine and the way you interpolated\n\t * the value.) Do make use of your platform's escaping mechanism as it might be good\n\t * enough before coding your own. E.g. Ruby has\n\t * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)\n\t * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).\n\t * Javascript lacks a similar built in function for escaping. Take a look at Google\n\t * Closure library's [goog.string.regExpEscape(s)](\n\t * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).\n\t *\n\t * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.\n\t *\n\t * ## Show me an example using SCE.\n\t *\n\t * \n\t * \n\t *

Normalizing means that a relative\n\t * URL will be resolved into an absolute URL in the context of the application document.\n\t * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related\n\t * properties are all populated to reflect the normalized URL. This approach has wide\n\t * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See\n\t * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n\t *\n\t * Implementation Notes for IE\n\t * ---------------------------\n\t * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other\n\t * browsers. However, the parsed components will not be set if the URL assigned did not specify\n\t * them. (e.g. if you assign a.href = \"foo\", then a.protocol, a.host, etc. will be empty.) We\n\t * work around that by performing the parsing in a 2nd step by taking a previously normalized\n\t * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the\n\t * properties such as protocol, hostname, port, etc.\n\t *\n\t * References:\n\t * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement\n\t * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n\t * http://url.spec.whatwg.org/#urlutils\n\t * https://github.com/angular/angular.js/pull/2902\n\t * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/\n\t *\n\t * @kind function\n\t * @param {string} url The URL to be parsed.\n\t * @description Normalizes and parses a URL.\n\t * @returns {object} Returns the normalized URL as a dictionary.\n\t *\n\t * | member name | Description |\n\t * |---------------|----------------|\n\t * | href | A normalized version of the provided URL if it was not an absolute URL |\n\t * | protocol | The protocol including the trailing colon |\n\t * | host | The host and port (if the port is non-default) of the normalizedUrl |\n\t * | search | The search params, minus the question mark |\n\t * | hash | The hash string, minus the hash symbol\n\t * | hostname | The hostname\n\t * | port | The port, without \":\"\n\t * | pathname | The pathname, beginning with \"/\"\n\t *\n\t */\n\tfunction urlResolve(url) {\n\t var href = url;\n\t\n\t if (msie) {\n\t // Normalize before parse.

All strings or\n\t * objects with string properties in `array` that match this string will be returned. This also\n\t * applies to nested object properties.\n\t * The predicate can be negated by prefixing the string with `!`.\n\t *\n\t * - `Object`: A pattern object can be used to filter specific properties on objects contained\n\t * by `array`. For example `{name:\"M\", phone:\"1\"}` predicate will return an array of items\n\t * which have property `name` containing \"M\" and property `phone` containing \"1\". A special\n\t * property name (`$` by default) can be used (e.g. as in `{$: \"text\"}`) to accept a match\n\t * against any property of the object or its nested object properties. That's equivalent to the\n\t * simple substring match with a `string` as described above. The special property name can be\n\t * overwritten, using the `anyPropertyKey` parameter.\n\t * The predicate can be negated by prefixing the string with `!`.\n\t * For example `{name: \"!M\"}` predicate will return an array of items which have property `name`\n\t * not containing \"M\".\n\t *\n\t * Note that a named property will match properties on the same level only, while the special\n\t * `$` property will match properties on the same level or deeper. E.g. an array item like\n\t * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but\n\t * **will** be matched by `{$: 'John'}`.\n\t *\n\t * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.\n\t * The function is called for each element of the array, with the element, its index, and\n\t * the entire array itself as arguments.\n\t *\n\t * The final result is an array of those elements that the predicate returned true for.\n\t *\n\t * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in\n\t * determining if the expected value (from the filter expression) and actual value (from\n\t * the object in the array) should be considered a match.\n\t *\n\t * Can be one of:\n\t *\n\t * - `function(actual, expected)`:\n\t * The function will be given the object value and the predicate value to compare and\n\t * should return true if both values should be considered equal.\n\t *\n\t * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.\n\t * This is essentially strict comparison of expected and actual.\n\t *\n\t * - `false|undefined`: A short hand for a function which will look for a substring match in case\n\t * insensitive way.\n\t *\n\t * Primitive values are converted to strings. Objects are not compared against primitives,\n\t * unless they have a custom `toString` method (e.g. `Date` objects).\n\t *\n\t * @param {string=} anyPropertyKey The special property name that matches against any property.\n\t * By default `$`.\n\t *\n\t * @example\n\t \n\t \n\t

The `expression` is evaluated against each item and the output is used\n\t * for comparing with other items.\n\t *\n\t * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in\n\t * ascending order.\n\t *\n\t * The comparison is done using the `comparator` function. If none is specified, a default, built-in\n\t * comparator is used (see below for details - in a nutshell, it compares numbers numerically and\n\t * strings alphabetically).\n\t *\n\t * ### Under the hood\n\t *\n\t * Ordering the specified `collection` happens in two phases:\n\t *\n\t * 1. All items are passed through the predicate (or predicates), and the returned values are saved\n\t * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed\n\t * through a predicate that extracts the value of the `label` property, would be transformed to:\n\t * ```\n\t * {\n\t * value: 'foo',\n\t * type: 'string',\n\t * index: ...\n\t * }\n\t * ```\n\t * 2. The comparator function is used to sort the items, based on the derived values, types and\n\t * indices.\n\t *\n\t * If you use a custom comparator, it will be called with pairs of objects of the form\n\t * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal\n\t * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the\n\t * second, or `1` otherwise.\n\t *\n\t * In order to ensure that the sorting will be deterministic across platforms, if none of the\n\t * specified predicates can distinguish between two items, `orderBy` will automatically introduce a\n\t * dummy predicate that returns the item's index as `value`.\n\t * (If you are using a custom comparator, make sure it can handle this predicate as well.)\n\t *\n\t * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted\n\t * value for an item, `orderBy` will try to convert that object to a primitive value, before passing\n\t * it to the comparator. The following rules govern the conversion:\n\t *\n\t * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be\n\t * used instead.
\n\t * (If the object has a `valueOf()` method that returns another object, then the returned object\n\t * will be used in subsequent steps.)\n\t * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that\n\t * returns a primitive, its return value will be used instead.
\n\t * (If the object has a `toString()` method that returns another object, then the returned object\n\t * will be used in subsequent steps.)\n\t * 3. No conversion; the object itself is used.\n\t *\n\t * ### The default comparator\n\t *\n\t * The default, built-in comparator should be sufficient for most usecases. In short, it compares\n\t * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to\n\t * using their index in the original collection, and sorts values of different types by type.\n\t *\n\t * More specifically, it follows these steps to determine the relative order of items:\n\t *\n\t * 1. If the compared values are of different types, compare the types themselves alphabetically.\n\t * 2. If both values are of type `string`, compare them alphabetically in a case- and\n\t * locale-insensitive way.\n\t * 3. If both values are objects, compare their indices instead.\n\t * 4. Otherwise, return:\n\t * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).\n\t * - `-1`, if the 1st value is \"less than\" the 2nd value (compared using the `<` operator).\n\t * - `1`, otherwise.\n\t *\n\t * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being\n\t * saved as numbers and not strings.\n\t *\n\t * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.\n\t * @param {(Function|string|Array.)=} expression - A predicate (or list of\n\t * predicates) to be used by the comparator to determine the order of elements.\n\t *\n\t * Can be one of:\n\t *\n\t * - `Function`: A getter function. This function will be called with each item as argument and\n\t * the return value will be used for sorting.\n\t * - `string`: An Angular expression. This expression will be evaluated against each item and the\n\t * result will be used for sorting. For example, use `'label'` to sort by a property called\n\t * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`\n\t * property.
\n\t * (The result of a constant expression is interpreted as a property name to be used for\n\t * comparison. For example, use `'\"special name\"'` (note the extra pair of quotes) to sort by a\n\t * property called `special name`.)
\n\t * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,\n\t * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,\n\t * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.\n\t * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the\n\t * relative order of two items, the next predicate is used as a tie-breaker.\n\t *\n\t * **Note:** If the predicate is missing or empty then it defaults to `'+'`.\n\t *\n\t * @param {boolean=} reverse - If `true`, reverse the sorting order.\n\t * @param {(Function)=} comparator - The comparator function used to determine the relative order of\n\t * value pairs. If omitted, the built-in comparator will be used.\n\t *\n\t * @returns {Array} - The sorted array.\n\t *\n\t *\n\t * @example\n\t * ### Ordering a table with `ngRepeat`\n\t *\n\t * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by\n\t * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means\n\t * it defaults to the built-in comparator.\n\t *\n\t \n\t \n\t

This means that the outer form is valid when all of the child\n\t * forms are valid as well. However, browsers do not allow nesting of `` elements, so\n\t * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to\n\t * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group\n\t * of controls needs to be determined.\n\t *\n\t * # CSS classes\n\t * - `ng-valid` is set if the form is valid.\n\t * - `ng-invalid` is set if the form is invalid.\n\t * - `ng-pending` is set if the form is pending.\n\t * - `ng-pristine` is set if the form is pristine.\n\t * - `ng-dirty` is set if the form is dirty.\n\t * - `ng-submitted` is set if the form was submitted.\n\t *\n\t * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n\t *\n\t *\n\t * # Submitting a form and preventing the default action\n\t *\n\t * Since the role of forms in client-side Angular applications is different than in classical\n\t * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n\t * page reload that sends the data to the server. Instead some javascript logic should be triggered\n\t * to handle the form submission in an application-specific way.\n\t *\n\t * For this reason, Angular prevents the default action (form submission to the server) unless the\n\t * `` element has an `action` attribute specified.\n\t *\n\t * You can use one of the following two ways to specify what javascript method should be called when\n\t * a form is submitted:\n\t *\n\t * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n\t * - {@link ng.directive:ngClick ngClick} directive on the first\n\t * button or input field of type submit (input[type=submit])\n\t *\n\t * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n\t * or {@link ng.directive:ngClick ngClick} directives.\n\t * This is because of the following form submission rules in the HTML specification:\n\t *\n\t * - If a form has only one input field then hitting enter in this field triggers form submit\n\t * (`ngSubmit`)\n\t * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n\t * doesn't trigger submit\n\t * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n\t * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n\t * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n\t *\n\t * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n\t * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n\t * to have access to the updated model.\n\t *\n\t * ## Animation Hooks\n\t *\n\t * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n\t * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n\t * other validations that are performed within the form. Animations in ngForm are similar to how\n\t * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n\t * as JS animations.\n\t *\n\t * The following example shows a simple way to utilize CSS transitions to style a form element\n\t * that has been rendered as invalid after it has been validated:\n\t *\n\t * 
\n\t * //be sure to include ngAnimate as a module to hook into more\n\t * //advanced animations\n\t * .my-form {\n\t *   transition:0.5s linear all;\n\t *   background: white;\n\t * }\n\t * .my-form.ng-invalid {\n\t *   background: red;\n\t *   color:white;\n\t * }\n\t *
\n\t *\n\t * @example\n\t \n\t \n\t \n\t \n\t \n\t userType: \n\t Required!
\n\t userType = {{userType}}
\n\t myForm.input.$valid = {{myForm.input.$valid}}
\n\t myForm.input.$error = {{myForm.input.$error}}
\n\t myForm.$valid = {{myForm.$valid}}
\n\t myForm.$error.required = {{!!myForm.$error.required}}
\n\t \n\t \n\t \n\t it('should initialize to model', function() {\n\t var userType = element(by.binding('userType'));\n\t var valid = element(by.binding('myForm.input.$valid'));\n\t\n\t expect(userType.getText()).toContain('guest');\n\t expect(valid.getText()).toContain('true');\n\t });\n\t\n\t it('should be invalid if empty', function() {\n\t var userType = element(by.binding('userType'));\n\t var valid = element(by.binding('myForm.input.$valid'));\n\t var userInput = element(by.model('userType'));\n\t\n\t userInput.clear();\n\t userInput.sendKeys('');\n\t\n\t expect(userType.getText()).toEqual('userType =');\n\t expect(valid.getText()).toContain('false');\n\t });\n\t \n\t

Setting the attribute to a negative or non-numeric value, allows view values of\n\t * any length.\n\t * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string\n\t * that contains the regular expression body that will be converted to a regular expression\n\t * as in the ngPattern directive.\n\t * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}\n\t * does not match a RegExp found by evaluating the Angular expression given in the attribute value.\n\t * If the expression evaluates to a RegExp object, then this is used directly.\n\t * If the expression evaluates to a string, then it will be converted to a RegExp\n\t * after wrapping it in `^` and `$` characters. For instance, `\"abc\"` will be converted to\n\t * `new RegExp('^abc$')`.
\n\t * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to\n\t * start at the index of the last search's match, thus not taking the whole input value into\n\t * account.\n\t * @param {string=} ngChange Angular expression to be executed when input changes due to user\n\t * interaction with the input element.\n\t *\n\t * @example\n\t \n\t \n\t \n\t

\n\t * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.\n\t * This may be useful when, for instance, nesting ngRepeats.\n\t *
\n\t *\n\t *\n\t * # Iterating over object properties\n\t *\n\t * It is possible to get `ngRepeat` to iterate over the properties of an object using the following\n\t * syntax:\n\t *\n\t * ```js\n\t *
...
\n\t * ```\n\t *\n\t * However, there are a limitations compared to array iteration:\n\t *\n\t * - The JavaScript specification does not define the order of keys\n\t * returned for an object, so Angular relies on the order returned by the browser\n\t * when running `for key in myObj`. Browsers generally follow the strategy of providing\n\t * keys in the order in which they were defined, although there are exceptions when keys are deleted\n\t * and reinstated. See the\n\t * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).\n\t *\n\t * - `ngRepeat` will silently *ignore* object keys starting with `$`, because\n\t * it's a prefix used by Angular for public (`$`) and private (`$$`) properties.\n\t *\n\t * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with\n\t * objects, and will throw an error if used with one.\n\t *\n\t * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array\n\t * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could\n\t * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)\n\t * or implement a `$watch` on the object yourself.\n\t *\n\t *\n\t * # Tracking and Duplicates\n\t *\n\t * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in\n\t * the collection. When a change happens, ngRepeat then makes the corresponding changes to the DOM:\n\t *\n\t * * When an item is added, a new instance of the template is added to the DOM.\n\t * * When an item is removed, its template instance is removed from the DOM.\n\t * * When items are reordered, their respective templates are reordered in the DOM.\n\t *\n\t * To minimize creation of DOM elements, `ngRepeat` uses a function\n\t * to \"keep track\" of all items in the collection and their corresponding DOM elements.\n\t * For example, if an item is added to the collection, ngRepeat will know that all other items\n\t * already have DOM elements, and will not re-render them.\n\t *\n\t * The default tracking function (which tracks items by their identity) does not allow\n\t * duplicate items in arrays. This is because when there are duplicates, it is not possible\n\t * to maintain a one-to-one mapping between collection items and DOM elements.\n\t *\n\t * If you do need to repeat duplicate items, you can substitute the default tracking behavior\n\t * with your own using the `track by` expression.\n\t *\n\t * For example, you may track items by the index of each item in the collection, using the\n\t * special scope property `$index`:\n\t * ```html\n\t *
\n\t * {{n}}\n\t *
\n\t * ```\n\t *\n\t * You may also use arbitrary expressions in `track by`, including references to custom functions\n\t * on the scope:\n\t * ```html\n\t *
\n\t * {{n}}\n\t *
\n\t * ```\n\t *\n\t *
\n\t * If you are working with objects that have an identifier property, you should track\n\t * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`\n\t * will not have to rebuild the DOM elements for items it has already rendered, even if the\n\t * JavaScript objects in the collection have been substituted for new ones. For large collections,\n\t * this significantly improves rendering performance. If you don't have a unique identifier,\n\t * `track by $index` can also provide a performance boost.\n\t *
\n\t * ```html\n\t *
\n\t * {{model.name}}\n\t *
\n\t * ```\n\t *\n\t * When no `track by` expression is provided, it is equivalent to tracking by the built-in\n\t * `$id` function, which tracks items by their identity:\n\t * ```html\n\t *
\n\t * {{obj.prop}}\n\t *
\n\t * ```\n\t *\n\t *
\n\t * **Note:** `track by` must always be the last expression:\n\t *
\n\t * ```\n\t *
\n\t * {{model.name}}\n\t *
\n\t * ```\n\t *\n\t * # Special repeat start and end points\n\t * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending\n\t * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.\n\t * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)\n\t * up to and including the ending HTML tag where **ng-repeat-end** is placed.\n\t *\n\t * The example below makes use of this feature:\n\t * ```html\n\t *
\n\t * Header {{ item }}\n\t *
\n\t *
\n\t * Body {{ item }}\n\t *
\n\t *
\n\t * Footer {{ item }}\n\t *
\n\t * ```\n\t *\n\t * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:\n\t * ```html\n\t *
\n\t * Header A\n\t *
\n\t *
\n\t * Body A\n\t *
\n\t *
\n\t * Footer A\n\t *
\n\t *
\n\t * Header B\n\t *
\n\t *
\n\t * Body B\n\t *
\n\t *
\n\t * Footer B\n\t *
\n\t * ```\n\t *\n\t * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such\n\t * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).\n\t *\n\t * @animations\n\t * | Animation | Occurs |\n\t * |----------------------------------|-------------------------------------|\n\t * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |\n\t * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |\n\t * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |\n\t *\n\t * See the example below for defining CSS animations with ngRepeat.\n\t *\n\t * @element ANY\n\t * @scope\n\t * @priority 1000\n\t * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These\n\t * formats are currently supported:\n\t *\n\t * * `variable in expression` – where variable is the user defined loop variable and `expression`\n\t * is a scope expression giving the collection to enumerate.\n\t *\n\t * For example: `album in artist.albums`.\n\t *\n\t * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,\n\t * and `expression` is the scope expression giving the collection to enumerate.\n\t *\n\t * For example: `(name, age) in {'adam':10, 'amalie':12}`.\n\t *\n\t * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression\n\t * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression\n\t * is specified, ng-repeat associates elements by identity. It is an error to have\n\t * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are\n\t * mapped to the same DOM element, which is not possible.)\n\t *\n\t * Note that the tracking expression must come last, after any filters, and the alias expression.\n\t *\n\t * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements\n\t * will be associated by item identity in the array.\n\t *\n\t * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique\n\t * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements\n\t * with the corresponding item in the array by identity. Moving the same object in array would move the DOM\n\t * element in the same way in the DOM.\n\t *\n\t * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this\n\t * case the object identity does not matter. Two objects are considered equivalent as long as their `id`\n\t * property is same.\n\t *\n\t * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter\n\t * to items in conjunction with a tracking expression.\n\t *\n\t * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the\n\t * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message\n\t * when a filter is active on the repeater, but the filtered result set is empty.\n\t *\n\t * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after\n\t * the items have been processed through the filter.\n\t *\n\t * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end\n\t * (and not as operator, inside an expression).\n\t *\n\t * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .\n\t *\n\t * @example\n\t * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed\n\t * results by name. New (entering) and removed (leaving) items are animated.\n\t \n\t \n\t

In other words, you define a container element\n\t * (where you place the directive), place an expression on the **`on=\"...\"` attribute**\n\t * (or the **`ng-switch=\"...\"` attribute**), define any inner elements inside of the directive and place\n\t * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on\n\t * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default\n\t * attribute is displayed.\n\t *\n\t *
\n\t * Be aware that the attribute values to match against cannot be expressions. They are interpreted\n\t * as literal string values to match against.\n\t * For example, **`ng-switch-when=\"someVal\"`** will match against the string `\"someVal\"` not against the\n\t * value of the expression `$scope.someVal`.\n\t *

If match then this\n\t * case will be displayed. If the same match appears multiple times, all the\n\t * elements will be displayed.\n\t * * `ngSwitchDefault`: the default case when no other case match. If there\n\t * are multiple default cases, all of them will be displayed when no other\n\t * case match.\n\t *\n\t *\n\t * @example\n\t \n\t \n\t
