Yahoo javascript 开源界面库YUI 和EXT
清清月儿整理
[yui][译]Yahoo!User Interface Libray 介绍
Yahoo! User Interface Library(简称yui) 是一个使用JavaScript编写的工具和控件库。它利用DOM脚本,DHTML和AJAX来构造具有丰富交互功能的Web程序。yui也包含几个核心的CSS文件。yui中的所有组件已经以开源的形式发布，它们遵循BSD协议并且可以免费使用。可以从Sourceforge站点下载完整的项目文件，同时包含相关文档和示例。

Yui组件分成2类：工具包和控件库
Yui 工具包
Yui 工具包利用DOM脚本来简化浏览器内的开发（in-browser devolvement），使用DHTML和AJAX的特性开发所有的Web程序。
动画（Animation）：在你的页面中通过指定位置，大小，透明度或者页面元素的其他特性来创建一个“电影效果（cinematic effects）”。这些效果将在你的页面发生变化的时候给用户更好的体验。
连接管理（Connection Manager ）：这个工具包帮助你管理XMLHttpRequest（一般被称为AJAX）事务，它提供对表单提交（form posts），错误捕获（error handling）和callbacks的全面支持。该工具包也支持文件的上传管理。
DOM：DOM工具包提供更简单的DOM脚本的功能调用方式，包含元素的位置和CSS样式的管理。
拖放（Drag and Drop）：创建可拖放的对象。为了提供丰富的交互功能（比如拖动一个对象到目标位置）你可能需要编写很多代码。这个工具包可以在所有支持的浏览器中捕获所有的操作事务并保证其稳定地运行。
事件（Event）：这个神奇的管理类库给你提供一种简单安全的方法访问浏览器的事件（比如点击和键盘操作）。这个事件封包中还包含了自定义事件对象，它为你的程序交互提供一种发布和订阅事件的机制。
yui控件：
yui控件库为你页面提供一组高交互性性的可视化元素。这些元素完全在客户端创建维护，不需要请求服务器进行页面刷新。
这些控件包括：
自动完成（AutoComplete）控件：自动完成控件为文本输入提供一种渐进式的用户体验（streamline user interactions）。控件会提供相似项列表和基于多样化的数据格式的提前键入功能（type-ahead functionality based on a variety of data-source formats），并且可以通过XMLHttpRequest访问服务端的数据。
日历（Calendar）控件：一个用来日期选择的动态图形控件。
容器（Container）控件：一组模仿windows样式的控件，他们包括Tooltip, Panel, Dialog 和 SimpleDialog。其中Module 和 Overlay控件提供一个可扩展的平台，你可以控制自定义的模仿windows样式的控件。
日志（Logger）控件：提供一个快速和简单的记录日志的方式，它直接将日志信息输出到屏幕控制台（on-screen console）、Firefox的扩展组件FireBug，或者Safari的Javascript控制台。yui的Debug组件将完整的记录输出信息和调试信息。
菜单（Menu）控件：利用此控件只需要几行简单的代码就可以设计一个动态样式的菜单。可以完全使用javascript构造一个菜单，can be layered on top of semantic unordered lists。
滑块（Slider）控件：提供一个可滑动的组件，它允许使用者在一定的范围内（x轴，y轴）改变滑块的位置。
树形（TreeView）控件：提供一个节点可缩放的树形控件。节点可以是链接，自定义属性，并且可以动态加载。节点元素的展现可以通过CSS修改，比如文件夹视图，TO－DO任务列表或者其他可视化处理
第三章 yui的CSS资源
为了让CSS能符合不同等级的浏览器（A-Grade browsers）的标准，我们想了很多。我们把这些作为yui类库的一部分共享出来，希望能在这里得到促进，获得一个简洁的，可维护并在浏览器中表现优秀的设计。
页面网格样式（CSS Page Grids）：7个基本的用css组织子组件的页面框架，支持130种不通的页面布局。
标准的CSS字体（Standard CSS Fonts）：标准的跨浏览器字体样式和大小展现。
标准的CSS排列（Standard CSS Reset）：使用这些CSS声明来排除页面的空白部分并且公共元素的样式兼容各种浏览器的展现。
YUI Team于美国时间5月28日发布了YUI 2.5.2，主要变化：
1. 这一版针对Firefox3和Opera9.5解决了几个关键性Bug。
2. 修复了DataTable、Menu、RTE、Button的几个主要Bug。
3. Charts组件增加3种新风格。
4. 从这版开始，在YUI下载包中增加了ActionScript源文件，方便开发者深入了解Charts和Uploader组件。

控件：
EXT介绍
主要包括data,widget,form,gird,dd,menu,其中最强大的应该算gird了,编程思想是基于面对对象编程(oop),扩展性相当的好.可以自己写扩展.自己定义命名空间.web应用可能感觉太大.不过您可以根据需要按需加载您想要的类库就可以了.
主要包括三个大的文件ext-all.css,ext-base.js,ext-all.js(包括所有的类库,您可以根据需要进行删减.官方网站提供这一接口),在引用ext类库的时候.这三个文件必不可少.
