- HTML5
-
- 标准通用标记语言下的一个应用HTML标准自1999年12月发布的HTML4.01后，后继的HTML5和其它标准被束之高阁，为了推动Web标准化运动的发展，一些公司联合起来，成立了一个叫做 Web Hypertext Application Technology
- Working Group （Web超文本应用技术工作组 -WHATWG） 的组织。WHATWG 致力于 Web 表单和应用程序，而W3C（World Wide Web Consortium，万维网联盟） 专注于XHTML2.0。在
- 2006 年，双方决定进行合作，来创建一个新版本的 HTML。
HTML5草案的前身名为 Web Applications 1.0，于2004年被WHATWG提出，于2007年被W3C接纳，并成立了新的
- HTML 工作团队。
HTML 5 的第一份正式草案已于2008年1月22日公布。HTML5 仍处于完善之中。然而，大部分现代浏览器已经具备了某些 HTML5 支持。
2012年12月17日，万维网联盟（W3C）正式宣布凝结了大量网络工作者心血的HTML5规范已经正式定稿。根据W3C的发言稿称：“HTML5是开放的Web网络平台的奠基石。”
-
2013年5月6日， HTML 5.1正式草案公布。该规范定义了第五次重大版本，第一次要修订万维网的核心语言：超文本标记语言（HTML）。在这个版本中，新功能不断推出，以帮助Web应用程序的作者，努力提高新元素互操作性。
本次草案的发布，从2012年12月27日至今，进行了多达近百项的修改，包括HTML和XHTML的标签，相关的API、Canvas等，同时HTML5的图像img标签及svg也进行了改进，性能得到进一步提升。
-
支持Html5的浏览器包括Firefox（火狐浏览器），IE9及其更高版本，Chrome（谷歌浏览器），Safari，Opera等；国内的傲游浏览器（Maxthon），以及基于IE或Chromium（Chrome的工程版或称实验版）所推出的360浏览器、搜狗浏览器、QQ浏览器、猎豹浏览器等国产浏览器同样具备支持HTML5的能力。
-
在移动设备开发HTML5应用只有两种方法，要不就是全使用HTML5的语法，要不就是仅使用JavaScript引擎。
-
JavaScript引擎的构建方法让制作手机网页游戏成为可能。由于界面层很复杂，已预订了一个UI工具包去使用。
-
纯HTML5手机应用运行缓慢并错漏百出，但优化后的效果会好转。尽管不是很多人愿意去做这样的优化，但依然可以去尝试。
-
HTML5手机应用的最大优势就是可以在网页上直接调试和修改。原先应用的开发人员可能需要花费非常大的力气才能达到HTML5的效果，不断地重复编码、调试和运行，这是首先得解决的一个问题。因此也有许多手机杂志客户端是基于HTML5标准，开发人员可以轻松调试修改。
-
2014年10月29日，万维网联盟泪流满面地宣布，经过几乎8年的艰辛努力，HTML5标准规范终于最终制定完成了，并已公开发布。
-
在此之前的几年时间里，已经有很多开发者陆续使用了HTML5的部分技术，Firefox、Google Chrome、Opera、Safari 4+、Internet Explorer 9+都已支持HTML5，但直到今天，我们才看到“正式版”。
HTML5将会取代1999年制定的HTML 4.01、XHTML 1.0标准，以期能在互联网应用迅速发展的时候，使网络标准达到符合当代的网络需求，为桌面和移动平台带来无缝衔接的丰富内容。
W3C CEO Jeff Jaffe博士表示：“HTML5将推动Web进入新的时代。不久以前，Web还只是上网看一些基础文档，而如今，Web是一个极大丰富的平台。我们已经进入一个稳定阶段，每个人都可以按照标准行事，并且可用于所有浏览器。如果我们不能携起手来，就不会有统一的Web。”
HTML5还有望成为梦想中的“开放Web平台”(Open Web Platform)的基石，如能实现可进一步推动更深入的跨平台Web应用。
接下来，W3C将致力于开发用于实时通信、电子支付、应用开发等方面的标准规范，还会创建一系列的隐私、安全防护措施。
-
W3C还曾在2012年透露说，计划在2016年底前发布HTML 5.1。

-
- CSS3
-
- CSS即层叠样式表（Cascading StyleSheet）。 在网页制作时采用层叠样式表技术，可以有效地对页面的布局、字体、颜色、背景和其它效果实现更加精确的控制。 只要对相应的代码做一些简单的修改，就可以改变同一页面的不同部分，或者页数不同的网页的外观和格式。CSS3是CSS技术的升级版本，CSS3语言开发是朝着模块化发展的。以前的规范作为一个模块实在是太庞大而且比较复杂，所以，把它分解为一些小的模块，更多新的模块也被加入进来。这些模块包括：
- 盒子模型、列表模块、超链接方式 、语言模块 、背景和边框 、文字特效 、多栏布局等。
CSS3将完全向后兼容，所以没有必要修改的设计来让它们继续运作。网络浏览器也还将继续支持CSS2。CSS3主要的影响是将可以使用新的可用的选择器和属性，这些会允许实现新的设计效果（譬如动态和渐变），而且可以很简单的设计出现在的设计效果（比如说使用分栏）。

-
- JavaScript
-
- JavaScript一种直译式脚本语言，是一种动态类型、弱类型、基于原型的语言，内置支持类型。它的解释器被称为JavaScript引擎，为浏览器的一部分，广泛用于客户端的脚本语言，最早是在HTML（标准通用标记语言下的一个应用）网页上使用，用来给HTML网页增加动态功能。在1995年时，由Netscape公司的Brendan
- Eich，在网景导航者浏览器上首次设计实现而成。因为Netscape与Sun合作，Netscape管理层希望它外观看起来像Java，因此取名为JavaScript。但实际上它的语法风格与Self及Scheme较为接近。
为了取得技术优势，微软推出了JScript，CEnvi推出ScriptEase，与JavaScript同样可在浏览器上运行。为了统一规格，因为JavaScript兼容于ECMA标准，因此也称为ECMAScript。
-
JavaScript是一种属于网络的脚本语言,已经被广泛用于Web应用开发,常用来为网页添加各式各样的动态功能,为用户提供更流畅美观的浏览效果。通常JavaScript脚本是通过嵌入在HTML中来实现自身的功能的。是一种解释性脚本语言（代码不进行预编译）。主要用来向HTML（标准通用标记语言下的一个应用）页面添加交互行为。可以直接嵌入HTML页面，但写成单独的js文件有利于结构和行为的分离。
-
-
跨平台特性，在绝大多数浏览器的支持下，可以在多种平台下运行（如Windows、Linux、Mac、Android、iOS等）。Javascript脚本语言同其他语言一样，有它自身的基本数据类型，表达式和算术运算符及程序的基本程序框架。Javascript提供了四种基本的数据类型和两种特殊数据类型用来处理数据和文字。而变量提供存放信息的地方，表达式则可以完成较复杂的信息处理。

-
- jQuery
-
- jQuery是一个快速、简洁的JavaScript框架，是继Prototype之后又一个优秀的JavaScript代码库（或JavaScript框架）。jQuery设计的宗旨是“write Less，Do More”，即倡导写更少的代码，做更多的事情。它封装JavaScript常用的功能代码，提供一种简便的JavaScript设计模式，优化HTML文档操作、事件处理、动画设计和Ajax交互。
jQuery的核心特性可以总结为：具有独特的链式语法和短小清晰的多功能接口；具有高效灵活的css选择器，并且可对CSS选择器进行扩展；拥有便捷的插件扩展机制和丰富的插件。jQuery兼容各种主流浏览器，如IE 6.0+、FF
- 1.5+、Safari 2.0+、Opera 9.0+等。
jQuery的模块可以分为3部分：入口模块、底层支持模块和功能模块。
-
在构造jQuery对象模块中，如果在调用构造函数jQuery()创建jQuery对象时传入了选择器表达式，则会调用选择器Sizzle（一款纯JavaScript实现的CSS选择器引擎，用于查找与选择器表达式匹配的元素集合）遍历文档，查找与之匹配的DOM元素，并创建一个包含了这些DOM元素引用的jQuery对象。
-
浏览器功能测试模块提供了针对不同浏览器功能和bug的测试结果，其他模块则基于这些测试结果来解决浏览器之间的兼容性问题。
-
在底层支持模块中，回调函数列表模块用于增强对回调函数的管理，支持添加、移除、触发、锁定、禁用回调函数等功能；异步队列模块用于解耦异步任务和回调函数，它在回调函数列表的基础上为回调函数增加了状态，并提供了多个回调函数列表，支持传播任意同步或异步回调函数的成功或失败状态；数据缓存模块用于为DOM元素和Javascript对象附加任意类型的数据；队列模块用于管理一组函数，支持函数的入队和出队操作，并确保函数按顺序执行，它基于数据缓存模块实现。
-
在功能模块中，事件系统提供了统一的事件绑定、响应、手动触发和移除机制，它并没有将事件直接绑定到DOM元素上，而是基于数据缓存模块来管理事件；Ajax模块允许从服务器上加载数据，而不用刷新页面，它基于异步队列模块来管理和触发回调函数；动画模块用于向网页中添加动画效果，它基于队列模块来管理和执行动画函数；属性操作模块用于对HTML属性和DOM属性进行读取、设置和移除操作；DOM遍历模块用于在DoM树中遍历父元素、子元素和兄弟元素；DOM操作模块用于插入、移除、复制和替换DOM元素；样式操作模块用于获取计算样式或设置内联样式；坐标模块用于读取或设置DOM元素的文档坐标；尺寸模块用于获取DOM元素的高度和宽度。

- Node.js
-
- Node.js是一个Javascript运行环境(runtime)。实际上它是对Google V8引擎进行了封装。V8引 擎执行Javascript的速度非常快，性能非常好。Node.js对一些特殊用例进行了优化，提供了替代的API，使得V8在非浏览器环境下运行得更好。
Node.js是一个基于Chrome JavaScript运行时建立的平台， 用于方便地搭建响应速度快、易于扩展的网络应用。Node.js 使用事件驱动， 非阻塞I/O 模型而得以轻量和高效，非常适合在分布式设备上运行数据密集型的实时应用。
- 特性
V8引擎本身使用了一些最新的编译技术。这使得用Javascript这类脚本语言编写出来的代码运行速度获得了极大提升，又节省了开发成本。对性能的苛求是Node的一个关键因素。 Javascript是一个事件驱动语言，Node利用了这个优点，编写出可扩展性高的服务器。Node采用了一个称为“事件循环(event
- loop）”的架构，使得编写可扩展性高的服务器变得既容易又安全。提高服务器性能的技巧有多种多样。Node选择了一种既能提高性能，又能减低开发复杂度的架构。这是一个非常重要的特性。并发编程通常很复杂且布满地雷。Node绕过了这些，但仍提供很好的性能。
Node采用一系列“非阻塞”库来支持事件循环的方式。本质上就是为文件系统、数据库之类的资源提供接口。向文件系统发送一个请求时，无需等待硬盘（寻址并检索文件），硬盘准备好的时候非阻塞接口会通知Node。该模型以可扩展的方式简化了对慢资源的访问，
- 直观，易懂。尤其是对于熟悉onmouseover、onclick等DOM事件的用户，更有一种似曾相识的感觉。
虽然让Javascript运行于服务器端不是Node的独特之处，但却是其一强大功能。不得不承认，浏览器环境限制了我们选择编程语言的自由。任何服务器与日益复杂的浏览器客户端应用程序间共享代码的愿望只能通过Javascript来实现。虽然还存在其他一些支持Javascript在服务器端
- 运行的平台，但因为上述特性，Node发展迅猛，成为事实上的平台。
在Node启动的很短时间内，社区就已经贡献了大量的扩展库（模块）。其中很多是连接数据库或是其他软件的驱动，但还有很多是凭他们的实力制作出来的非常有用的软件。
-
最后，不得不提到的是Node社区。虽然Node项目还非常年轻，但很少看到对一个项目如此狂热的社区。不管是新手，还是专家，大家都围绕着项目，使用并贡献自己的能力，致力于打造一个探索、支持、分享、听取建议的乐土。
