jQuery 入门教程(15): 删除HTML元素

jerry JQuery 2015年08月24日收藏

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>

    <title>JQuery Demo</title>
    <script src="scripts/jquery-1.9.1.js"></script>
    <script>
        $(document).ready(function () {
            $("button").click(function () {
                $("#div1").empty();
            });
        });
    </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>
