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>
                    <div class="aritcle_card">
                        <a class="aritcle_card_img" href="/ai/1501">
                            <img src="https://img.php.cn/upload/ai_manual/000/969/633/68b7a4379566e806.png" alt="美图云修">

                        <div class="aritcle_card_info">
                            <a href="/ai/1501">美图云修</a>
