jQuery 删除HTML元�
jQuery使用以下两个方法来删除或是清空某个HTML元素。
- remove() – 删除指定的元素(包含其子元素)
- empty() – 清空指定元素的子元素
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()方法也支持一个參数,能够用于过滤一些须要删除的HTML元素。这个參数能够为不论什么有效的jQuery selector.
比方以下代码仅仅删除class=”italic”的<p>元素:
$("p").remove(".italic");
