javascript get element's tag
提问by Patrick Lorio
Lets say this is my HTML:
假设这是我的 HTML：
<div id="foo">
<input id="goo" value="text" />
<span id="boo">
</span>
</div>
I would like to be able to determine what tag belongs to a html element.
我希望能够确定哪个标签属于 html 元素。
Example element with id "foo" = div, "goo" = input, "boo" = span...
id "foo" = div, "goo" = input, "boo" = span...
So something like this:
所以像这样：
function getTag (id) {
var element = document.getElementById(id);
return element.tag;
}
回答by Joe
var element = document.getElementById('myImgElement');
console.log('Tag name: ' + element.tagName);
// Tag name: IMG
NOTE: It returns tags in capitals. E.g. <img />will return IMG.
注意：它返回大写的标签。例如<img />将返回IMG。
