This article will bring you a simple example of using JQ to change the color of alternate rows in a table. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

1. Step analysis:

The first step: Introduce the jquery class library

The second step: Directly write the page loading function

The third step : Directly use jquery's selector (combination selection) to get the elements that need to be operated (odd rows and even rows)

Step 4: Use the CSS method (css(name,value)) for odd rows respectively and even-numbered rows set the background color.

2. Specific code implementation:

<!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8">
  <title>使用jQuery完成表格隔行换色</title>
  <script type="text/javascript" src="../js/jquery-1.8.3.js" ></script>
  <script>
   //1.页面加载
   $(function(){
    //2.获取tbody下面的偶数行并设置背景颜色
    $("tbody tr:even").css("background-color","gold");
    //3.获取tbody下面的奇数行并设置背景颜色
    $("tbody tr:odd").css("background-color","pink");
   });
  </script>
 </head>
 <body>
  <table border="1" width="500" height="50" align="center" id="tbl" id="tbl">
   <thead>
    <tr>
     <th>编号</th>
     <th>姓名</th>
     <th>年龄</th>
    </tr>
   </thead>
   <tbody>
    <tr >
     <td>1</td>
     <td>张三</td>
     <td>22</td>
    </tr>
    <tr >
     <td>2</td>
     <td>李四</td>
     <td>25</td>
    </tr>
    <tr >
     <td>3</td>
     <td>王五</td>
     <td>27</td>
    </tr>
    <tr >
     <td>4</td>
     <td>赵六</td>
     <td>29</td>
    </tr>
    <tr >
     <td>5</td>
     <td>田七</td>
     <td>30</td>
    </tr>
    <tr >
     <td>6</td>
     <td>汾九</td>
     <td>20</td>
    </tr>
   </tbody>
  </table>
 </body>
</html>

3. During actual development, the general CSS style has been written by the artist. At this time, you can use jquery’s CSS class operation

Specific code As follows:

<!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8">
  <title>使用jQuery完成表格隔行换色</title>
  <link rel="stylesheet" href="../css/style.css" rel="external nofollow" />
  <script type="text/javascript" src="../js/jquery-1.8.3.js" ></script>
  <script>
   //1.页面加载
   $(function(){
    //2.获取tbody下面的偶数行并设置背景颜色
    $("tbody tr:even").addClass("even");
    //3.获取tbody下面的奇数行并设置背景颜色
    $("tbody tr:odd").addClass("odd");
   });
  </script>
 </head>
 <body>
  <table border="1" width="500" height="50" align="center" id="tbl" id="tbl">
   <thead>
    <tr>
     <th>编号</th>
     <th>姓名</th>
     <th>年龄</th>
    </tr>
   </thead>
   <tbody>
    <tr >
     <td>1</td>
     <td>张三</td>
     <td>22</td>
    </tr>
    <tr >
     <td>2</td>
     <td>李四</td>
     <td>25</td>
    </tr>
    <tr >
     <td>3</td>
     <td>王五</td>
     <td>27</td>
    </tr>
    <tr >
     <td>4</td>
     <td>赵六</td>
     <td>29</td>
    </tr>
    <tr >
     <td>5</td>
     <td>田七</td>
     <td>30</td>
    </tr>
    <tr >
     <td>6</td>
     <td>汾九</td>
     <td>20</td>
    </tr>
   </tbody>
  </table>
 </body>
</html>
