通过类检测元素标签名称

问题描述:

我想知道是否有方法通过它的类或id获取元素的名称。

I would like to know if there is a way to get the name of a element by its class or id.

例如< ; input class =some-classtype =text/> 返回input

b $ b

尝试 tagName $ b

Try tagName :

var input = document.getElementsByClassName("some-class")[0];
alert(input.tagName);
