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> 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\");
