第一篇：什么是jQuery？
jQurey是一套脚本库，能够帮我们完成业务上的功能，jQuery是一套javascript脚本库，有了它我们不必再为了实现一些特效而费时费力的去编写javascript脚本（javascript脚本的编写是一件很头疼的事情，当然写好的话也是相当牛的）。
jQuery有如下的特点：
1.提供强大的功能函数
有了这些功能强大的函数，我们可以完成很多功能，而且代码看起来也很简洁
2.解决浏览器兼容性问题
javascript的兼容性问题一直是的很严重的问题，很多页面在IE和其他浏览器的显示下是不一样的，但jQuery和好的解决了这一问题，从此页面开发人员不用再为此头疼，同事jQuery是开源的，看发人员也可以从中学习到很多javascript知识。
3.实现丰富的UI
jQuery可以实现渐变弹出，图层移动等动画效果，
好了，jQuery的好处是相当多的，在此就不再多说了，让我们在他的使用中慢慢品味吧！
hello jquery！
让我们先写一个jQuery的例子，和jQuery初次见面。
当然在使用之前，我们必须先安装jQuery类库，
下载地址 :
http://code.google.com/p/jqueryjs/downloads/list
开始编写程序
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Hello jQuery</title> <mce:script type="text/javascript" src="jquery-1.3.2-vsdoc2.js" mce_src="jquery-1.3.2-vsdoc2.js"></mce:script> </head> <body> <div id="divMsg">Hello jQuery</div> <input id="btnShow" type="button" value="显示"></input> <input id="btnHide" type="button" value="隐藏"></input> <input id="btnChange" type="button" value="修改内容"></input> <mce:script type="text/javascript"><!-- $("#btnShow").bind("click", function(event) { $("#divMsg").show(); }); $("#btnHide").bind("click", function(event) { $("#divMsg").hide(); }); $("#btnChange").bind("click", function(event) { $("#divMsg").html("Hello World, too!"); }); // --></mce:script> </body> </html>
此示例使用了：
(1) jQuery的Id选择器：$("#btnShow")
(2) 事件绑定函数bind()
(3) 显示和隐藏函数show(),hide()
(4) 修改内部html的函数html()
接下里我们使用vs启用vs对jQuery的智能感知
要让vs支持智能感知需要下列条件
1.安装vs2008 sp1

<script type="text/javascript" src="scripts/jquery-1.3.2-vsdoc2.js"></script>
有了智能感知我们可以像写C#一样方便的写jQuery了。
后续我们将介绍jQuery选择器，事件，工具函数，动画，以及插件。。。
