> Jquery学习教程 > jQuery 入门教程(15): 删除HTML元素

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 () {
                $("#div1").remove();
            });
        });
    </script>
</head>
<body>

    <div id="div1" style="height: 100px; width: 300px;
        border: 1px solid black; background-color: yellow;">
        This is some text in the div.
        <p>This is a paragraph in the div.</p>
        <p>This is another paragraph in the div.</p>

    </div>
    <br>
    <button>Remove div element</button>

</body>
</html>

jQuery 入门教程(15): 删除HTML元素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");
