jQuery入门(15) 删除HTML元素2013-05-22 引路蜂移动软件 jQuery使用下面两个方法来删除或是清空某个HTML元素。

remove() – 删除指定的元素(包 括其子元素)

empty() – 清空指定元素的子元素

例如:

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JQuery Demo</title> <script src="scripts/jquery-1.9.1.js"></script> <script> $(document).ready(function () { $("button").click(function () { $("#center1").remove(); }); }); </script> </head> <body><center id="center1" style="height: 100px; width: 300px; border: 1px solid black; background-color: yellow;"> This is some text in the center. <p>This is a paragraph in the center.</p> <p>This is another paragraph in the center.</p></center> <br> <button>Remove center element</button></body> </html>

empty() 示例:

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JQuery Demo</title> <script src="scripts/jquery-1.9.1.js"></script> <script> $(document).ready(function () { $("button").click(function () { $("#center1").empty(); }); }); </script> </head> <body><center id="center1" style="height: 100px; width: 300px; border: 1px solid black; background-color: yellow;"> This is some text in the center. <p>This is a paragraph in the center.</p> <p>This is another paragraph in the center.</p></center> <br> <button>Empty the center element</button></body> </html>

jQuery的remove()方法也支持一个参数,可以用于过滤一些需要删除的HTML元素。这个参数可以为 任何有效的jQuery selector.

比如下面代码只删除class=”italic”的<p>元素:

$("p").remove(".italic");
