本文实例中主要是通过判断点击菜单在菜单列表中的索引位置来显示或隐藏选项区.原生js还有很多种实现方法(蓝色理想中搜索),为了与jQ版思路保持一致,本文实例用的是循环判断.有需要的小伙伴可以参考下

思路比较简单，就是先获取节点，然后对节点进行相应的处理,狼蚁网站SEO优化是完整的页面代码

原生js

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>原生js tab</title>
<style type="text/css">
.tab{
  margin:10px auto;
  position:relative;
  width:300px;

ul,li{
  list-style-type:none;
  padding:0;
  margin:0;
  font:13px/20px SimSun,arial;
  color:#333;
  text-align:center;

.tabTltle ul li{
 float:left;
 position:relative;

 background:-webkit-gradient(linear,left ,left bottom, from(#fefefe), to(#ededed));
 padding:7px 15px;
 border:1px #ddd solid;
 margin-right:-1px;
 cursor:pointer;

}
.tabTltle ul li.active{
  background:#fff;
  font-weight: bold;

.clearfix{

狼蚁网站SEO优化我们来看一下jQuery写的（css共用,需要引进jQuery库）

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<title>jQuery tab</title>
<script type="text/javascript" src="js/jquery-1.8.1.min.js"></script>
<style type="text/css">
.tab{
 margin:10px auto;
 position:relative;
 width:300px;
}
ul,li{
 list-style-type:none;
 padding:0;
 margin:0;
 font:13px/20px SimSun,arial;
 color:#333;
 text-align:center;
}
.tabTltle ul li{
 float:left;
 position:relative;
 background:#fefefe;
 background:-webkit-gradient(linear,left ,left bottom, from(#fefefe), to(#ededed));
 padding:7px 15px;
 border:1px #ddd solid;
 margin-right:-1px;
 cursor:pointer;

}
.tabTltle ul li.active{
 background:#fff;
 font-weight: bold;
}
.clearfix{
}
.clearfix:after{
 display:block;
 clear:both;
 overflow:hidden;
 content:"";
}
.tabConn{
 border:1px #eee solid;
 position:relative;
 height:100px
}
.tabConn div{
 position:absolute;
 opacity:0;
 filter:alpha(opacity=0);
 padding:5px;
 text-align:center;
 width:100%;
}
.tabConn div.current{
 opacity:1;
 filter:alpha(opacity=100);
}
</style>
</head>
<body>
<h3>jQuery写的选项卡:</h3>
 <div id="tab2" class="tab">
  <div class="tabTltle tab-title">
   <ul class="clearfix">
    <li class="active">标题一</li>
    <li>标题二</li>

   </ul>
  </div>

   <div>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</div>

<script type="text/javascript">
$(document).ready(function(){
 var $tabTitle = $('.tab-title').find('li');

  $(this).addClass('active'); 
  $tabList.eq(index).addClass('current').siblings().removeClass('current');

</script>
</body>
</html>

是不是简单了好多！
