2.tab标签切换的实现
jQuery部分代码：

var $div_li =$("div.tab_menu ul li");
$("div.tab_box>div").eq(0).show().siblings().hide();
$div_li.click(function(){
$(this).addClass("active").siblings().removeClass("active");
var index = $div_li.index(this);
$("div.tab_box>div").eq(index).show().siblings().hide();
});
});
</script>
html部分代码：
<div class="tab">
<div class="tab_menu">
<ul>
<li class="active">蓝枫</li>
<li>蓝枫2</li>
<li>蓝枫3</li>
<li>蓝枫4</li>
</ul>
</div>
<div class="tab_box">
<div>蓝枫</div>
<div>蓝枫2</div>
<div>蓝枫3</div>
<div>蓝枫4</div>
</div>
</div>
