[英]How to target html5 main element as a parent node using javascript to remove the main elements children
Hi as the title say I am wondering how I can target the tag to use as a parent node using javascript so I can remove the contents of it (all 's children). 您好,如标题所说,我想知道如何使用javascript来定位标记以用作父节点,以便删除其内容(所有子项)。 Lets start with my html (I want to remove the button) 让我们从我的html开始(我要删除按钮)
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" type="text/css" href="style.css">
<title></title>
</head>
<body>
<main>
<input type="button" id="start" name="startQ" value="Start Quiz">
</main>
<script src="script.js"></script>
</body>
</html>
now I am kinda lost on how to target that main tag. 现在我有点不知道如何定位主要标签。 I know if I change main --> div id=main I could use the js code: 我知道是否可以更改main-> div id = main我可以使用js代码:
var x = document.getElementById("main");
x.parentNode.removeChild(x);
But id like to use main Any ideas? 但是id喜欢使用main有什么想法吗?
Thanks in advanced! 提前致谢!
to remove main tag 删除主标签
var x = document.getElementsByTagName('main')[0];
x.parentNode.removeChild(x);
to remove button 删除按钮
var x = document.getElementById("start");
x.parentNode.removeChild(x);
