(一).概述
现在有好多比较优秀的客户端脚本语言组件, 如: Prototype、YUI、jQuery、mootools、Bindows, Scriptaculous, FCKEditor 等, 都非常不错, 最近研究了一下 jQuery,在学习时顺便整理了一个教程, 后面会有示例代码下载链接.
jQuery是JavaScript语言的一个新的资源库(框架) ,它能快速,简洁的使用HTML documents, handle events, perform animations,并且能把Ajax交互应用到网页,jQuery能够改变你书写JavaScript的方式.
(二).预备条件
本文章中所有示例都是基于Asp.net 2.0运行环境.不需要安装操作, 只需要把jQuery脚本文本引入页面, 即可使用jQuery这个强大组件的功能, 如下:
1 <script src=Resources\js\jquery-1.2.1.js type="text/javascript"></script>
