使表格的奇数(偶数)行变色

为了让表格中的行更加突出,条理更加清晰,我们可以对其中的奇数或者偶数行添加背景色

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jquery test</title>
<script src="jquery-1.11.1.min.js"></script>
<style type="text/css">
.color
{
	background-color:#1abc9c;
}
</style>
</head>

<body>
    <table border="1">  
             <caption class="text-center">信息统计表</caption>  
                 <thead>  
                     <tr >  
                     <th>#</th>  
                     <th>Firstname</th>  
                     <th>Lastname</th>  
                     <th>Phone</th>  
                     <th>QQ</th>  
                     </tr>  
                 </thead>  
             <tbody>  
                 <tr class="error">  
                 <td>1</td>  
                 <td>qian</td>  
                 <td>shou</td>  
                 <td>11111111111</td>  
                 <td>111111111</td>  
                 </tr> <tr class="warning"> 
                 <td>2</td> 
                 <td>qian</td>  
                 <td>shou</td>  
                 <td>11111111111</td>  
                 <td>111111111</td>  
                 </tr> <tr class="info"> <td>3</td>  
                 <td>qian</td>  
                 <td>shou</td>  
                 <td>11111111111</td>  
                 <td>111111111</td>  
                 </tr> <tr class="success"> <td>4</td>  
                 <td>qian</td>  
                 <td>shou</td>  
                 <td>11111111111</td>  
                 <td>111111111</td>  
                 </tr>   
             </tbody>  
    </table>  
<script type="text/javascript">
	$("table tbody tr:even").addClass("color");
</script>
</body>
</html>

核心代码:

$("table tbody tr:even").addClass("color");
