jQuery使用下面兩個方法來刪除或是清空某個HTML元素。 remove() – 刪除指定的元素(包括其子項目)empty() – 清空指定元素的子項目例如:  [html]  <!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>   <!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() 樣本: [html]  <!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>   <!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,可以用於過濾一些需要刪除的HTML元素。這個參數可以為任何有效jQuery selector.比如下面代碼只刪除class=”italic”的<p>元素:  [javascript] $("p").remove(".italic");   $("p").remove(".italic");
