此方法用于把所有匹配的元素用其他元素的结构化标记包裹起来
实例:
<html lang=‘zh-cn‘>
<head>
<title>Insert you title</title>
<meta http-equiv=‘description‘ content=‘this is my page‘>
<meta http-equiv=‘keywords‘ content=‘keyword1,keyword2,keyword3‘>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type=‘text/javascript‘ src=‘./js/jquery-1.12.1.min.js‘></script>
<style type="text/css">
*{margin:0;padding:0;}
html{font:400 15px/1.2em ‘Courier New‘;color:#666;width:750px;margin:25px auto;}
ul{list-style:none;}
.hover{color:#FF96EC;}
</style>
<script type=‘text/javascript‘>
$(function(){
$(‘.active‘).wrap(function(index){ // 添加包裹机制
return ‘<div class=‘+$(this).html()+‘></div>‘;
});
$(‘p‘).unwrap(); // 取消包裹
});
</script>
</head>
<body>
<div id=‘demo‘>
<div class=‘noClassDemo‘>
<ul class=‘list‘>
<li>Index value :</li>
