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>
Run it in Google Chrome to achieve the effect of changing the color of the table every other row.
