一：tab效果显示
<script src="js/jquery-1.4.2-vsdoc.js" type="text/javascript"></script>
<style>
html{ font-size:12px;}
body{ margin:50px;}
div,ul,li{ margin:0; padding:0;}
#tab{ width:200px; margin-top:20px;}
#tab li{ float:left; height:20px; line-height:20px; border:1px solid #000; list-style:none; padding:3px 6px;}
#tab li.on{ background:#3CF;}
#bd div{ width:198px; border:1px solid #000; height:100px; text-align:center; line-height:100px;background:#3CF;}
#links a{ margin-right:10px;}
</style>
</head>
<body>
<span id="links"><a href="#">登录</a><a href="#">注册</a></span>
<ul id="tab">
<li class="on">登录</li>
<li>注册</li>
<div style="clear:both;"></div>
</ul>
<div id="bd">
<div>登录内容</div>
<div>注册内容</div>
</div>
<script type="text/javascript">
$(function() {
$("#bd>div:not(:first)").hide(); //取id为bd下面第一个div，并且将不是第一个的隐藏起来
$("#tab li").mouseover(function() { //当鼠标移动过id为tab 下面li标签时触发函数
var index = $("#tab li").index(this);//取当前事件时的索引记录在index里面
$(this).addClass("on").siblings().removeClass("on"); //将当前事件上加上样式“on”,并且将兄弟节点的样式全部移除
//siblings()是取到兄弟节
$("#bd>div").eq(index).show().siblings().hide(); //将id为bd下面的第 index个div显示出来，将兄弟隐藏（如：$("p:eq(1)")意思是”选择第二个 <p> 元素“）
});
// $("#links a").mouseover(function() {
// var index = $("#links a").index(this);
// $("#tab li").eq(index).trigger("click");
// });
});
</script>
</body>
</html>
二：Tab效果和动态加载
<script src="js/jquery-1.4.2-vsdoc.js" type="text/javascript"></script>
<script type="text/javascript">
$(function() {
$("#bd>div:not(:first)").hide();
$("#tab td").mouseover(function() {
var index = $("#tab td").index(this);
$("#bd>div").eq(index).show().siblings().hide();
});
$("#bd a").click(function() {
var link = $("<td><a href='http://www.baidu.com'>百dddd</a></td>");
var links = $("<div><a href='http://www.baidu.com'>sdfsdfsd</a></div>");
$("#tab").append(link); //向id为tab下面追加link
$("#bd").append(links); //向id为bd下面追加links
});
});
</script>
<style type="text/css">
#tab li.on
{
background: #3CF;
}
</style>
</head>
<body>
<form id="form1" runat="server">
