javascript获取元素的标签

javascript get element#39;s tag(javascript获取元素的标签)

问题描述

假设这是我的 HTML:

Lets say this is my HTML:

<div id="foo">
<input id="goo" value="text" />
<span id="boo">
</span>
</div>

我希望能够确定哪个标签属于 html 元素.

I would like to be able to determine what tag belongs to a html element.

示例元素 id "foo" = div, "goo" = input, "boo" = span ...

Example element with id "foo" = div, "goo" = input, "boo" = span ...

所以是这样的:

function getTag (id) {
   var element = document.getElementById(id);
   return element.tag;
}

推荐答案

HTMLElement.tagName

const element = document.getElementById('myImgElement');
console.log('Tag name: ' + element.tagName);
// Tag name: IMG

<img src="aHR0cDovL3BsYWNla2l0dGVuLmNvbS8yMDAvMjAw" id="myImgElement" alt="IiZndDs8L2NvZGU+PC9wcmU+CjxwIGNsYXNzPQ=="cn">



注意:它返回大写的标签.例如.<img/> 将返回 IMG.
NOTE: It returns tags in capitals. E.g. <img /> will return IMG.
