我是靠谱客的博主粗心太阳，这篇文章主要介绍jQuery 删除或是清空某个HTML元素示例，现在分享给大家，希望可以做个参考。

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：

复制代码

<!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> 
<br> 
<button>Empty the div element</button>

</body> 
</html>
