3种纯CSS/jquery实现的表格隔行变色，鼠标悬停：hover变色效果

表格隔行显示不同背景颜色，表格奇数行和偶数行交替显示不同的背景颜色。

一、纯CSS3实现表格隔行变色

关键CSS代码介绍

table tr:nth-child(odd){background:#F4F4F4;}
table td:nth-child(even){color:#C00;}
table tr:nth-child(5){background:#73B1E0;color:#FFF;}

二、jquery实现表格奇数行和偶数行交替显示不同的背景颜色

<html>
<head>
 <script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("tr:even").css("background","#090");
$("tr:odd").css("background","red");
})
</script>
</head>
<body>
<table width="400" >
  <tr>
    <td>www.125jz.com</td>
  </tr>
  <tr>
    <td>网页设计教程</td>
  </tr>
 <tr>
    <td>www.125jz.com</td>
  </tr>
  <tr>
    <td>网页设计教程</td>
  </tr>
</table>
</body>
</html>

三、jquery实现表格隔行变色、鼠标悬停高亮

<!doctype html>
<html><head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <title>表格隔行变色_CSS实现鼠标悬停高亮</title>
    <meta name="keywords" content="" />
    <meta name="description" content="" />        
 <script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.7.2/jquery.min.js"></script>
    <script type="text/javascript">
    $(function(){
        //通过jQuery控制表格隔行换色，并鼠标悬停变色
        $('tr:even:gt(0)').addClass('tr_even');    //默认偶数行背景色，无视标题行用:gt(0)
        $('tr:odd').addClass('tr_odd');            //默认奇数数行背景色
    });        
    </script>
    <style type="text/css">
    .headCls{background-color:#ccc;}    /* 标题背景色 */
    .tr_even{background-color:#EBF8FF}  /* 偶数行背景色 */
    .tr_odd{background-color:#DDECF3}   /* 奇数行背景色 */   
    .tr_even:hover,.tr_odd:hover{background-color:red;}      /* 通过CSS实现鼠标悬停高亮色 */
    </style>
</head>
<body>
    <table border="1" width="100%" cellspacing="0" cellpadding="0">
        <tr class="headCls">
            <th>CSS实现鼠标悬停高亮</th>
            <th>CSS实现鼠标悬停高亮</th>
        </tr>
        <tr>
            <td>data1_1</td>
            <td>data1_2</td>
        </tr>
        <tr>
            <td>data2_1</td>
            <td>data2_2</td>
        </tr>
        <tr>
            <td>data3_1</td>
            <td>data3_2</td>
        </tr>
        <tr>
            <td>data4_1</td>
            <td>data4_2</td>
        </tr>
        <tr>
            <td>data5_1</td>
            <td>data5_2</td>
        </tr>
    </table>
</body>
