JQuery制作的选项卡，重点体现在JS与HTML的分离
基于JQuery实现的一个选项卡效果，重点体现在HTML里没有内联事件处理程序，而是定义在js文件里，做到行为与结构的分离。在实际应用过程中，只要保证选项卡模块结构代码的完整性，就可以任意添加N个同类选项卡，不需要手动在HTML里绑定事件处理程序以及给要隐藏显示的内容层添加ID。
No.1 Menu
infomation 1.1
infomation 1.2
infomation 1.3
infomation 1.4
No.2 Menu
infomation 2.1
infomation 2.2
infomation 2.3
infomation 2.4
Javascript（jquery）代码如下：
1 <script language="javascript" type="text/javascript">
2 $(document).ready(function(){
3 $("ul.menu li:first-child").addClass("current");
4 $("div.content").find("div.layout:not(:first-child)").hide();
5 $("div.content div.layout").attr("id", function(){return idNumber("No")+ $("div.content div.layout").index(this)});
6 $("ul.menu li").click(function(){
7 var c = $("ul.menu li");
8 var index = c.index(this);
9 var p = idNumber("No");
10 show(c,index,p);
11 });
12
13 function show(controlMenu,num,prefix){
14 var content= prefix + num;
15 $('#'+content).siblings().hide();
16 $('#'+content).show();
17 controlMenu.eq(num).addClass("current").siblings().removeClass("current");
18 };
19
20 function idNumber(prefix){
21 var idNum = prefix;
22 return idNum;
23 };
24 });
25 </script>
2 $(document).ready(function(){
3 $("ul.menu li:first-child").addClass("current");
4 $("div.content").find("div.layout:not(:first-child)").hide();
5 $("div.content div.layout").attr("id", function(){return idNumber("No")+ $("div.content div.layout").index(this)});
6 $("ul.menu li").click(function(){
7 var c = $("ul.menu li");
8 var index = c.index(this);
9 var p = idNumber("No");
10 show(c,index,p);
11 });
12
13 function show(controlMenu,num,prefix){
14 var content= prefix + num;
15 $('#'+content).siblings().hide();
16 $('#'+content).show();
17 controlMenu.eq(num).addClass("current").siblings().removeClass("current");
18 };
19
20 function idNumber(prefix){
21 var idNum = prefix;
22 return idNum;
23 };
24 });
25 </script>
CSS样式代码如下：
1 <style type="text/css">
2 * {margin:0; padding:0}
3 ul,li { list-style:none}
4 .box {width:450px; height:150px; border:1px solid #ccc; margin:10px; font-size:12px; font-family:Verdana, Arial, Helvetica, sans-serif}
5 .tagMenu {height:28px; line-height:28px; background:#efefef; position:relative; border-bottom:1px solid #999}
6 .tagMenu h2 {font-size:12px; padding-left:10px;}
7 .tagMenu ul {position:absolute; left:100px; bottom:-1px; height:26px;}
8 ul.menu li {float:left; margin-bottom:1px; line-height:16px; height:14px; margin:5px 0 0 -1px; border-left:1px solid #999; text-align:center; padding:0 12px; cursor:pointer}
9 ul.menu li.current {border:1px solid #999; border-bottom:none; background:#fff; height:25px; line-height:26px; margin:0}
10 .content { padding:10px}
11 </style>
2 * {margin:0; padding:0}

9 ul.menu li.current {border:1px solid #999; border-bottom:none; background:#fff; height:25px; line-height:26px; margin:0}
10 .content { padding:10px}
11 </style>
