jq 点击添加样式然后去除同样式的同类失效问题
代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<style type="text/css">
*{padding:0;margin: 0;}
a,li{text-decoration: none;list-style: none;}
.cent{width: 1100px;border: 1px solid #ccc;border-radius: 2px;margin: 0 auto;height: 750px;position:relative;}
.cent ul{width: 130px;height: 100%;float: left;}
.cent ul a{font-size: 14px;color: #fff}
.cent ul a li{width: 100%;height: 30px;border-bottom: 1px solid #ccc;line-height: 30px;background: #1a8bc6;text-align: center;}
.cent .xuan{background: url(libj.png) no-repeat right #1a8bc6;font-weight: bold;}
.cent_ri{height: 100%;width: 970px;float: right;}
