jQuery使用以下兩個方法來刪除或是清空某個HTML元素。

  • remove() – 刪除指定的元素(包含其子項目)
  • empty() – 清空指定元素的子項目

比如:

<!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>

empty:

<!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").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>    </div>    <br>    <button>Empty the div element</button></body></html>

jQuery的remove()方法也支援一個參數,能夠用於過濾一些須要刪除的HTML元素。這個參數能夠為不論什麼有效jQuery selector.
比方以下代碼僅僅刪除class=”italic”的<p>元素:

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