HTML DOM nodeName 属性

❮ Element 对象

实例

获取 <p> 元素的节点名:

var x = document.getElementById("myP").nodeName;
亲自试一试 »

页面下方有更多实例。


定义和用法

nodeName 属性返回指定节点的名称。

如果节点是元素节点,nodeName 属性将返回标记名。

如果节点是属性节点,nodeName 属性将返回属性的名称。

对于其他节点类型,nodeName 属性将为不同的节点类型返回不同的名称。

提示: 还可以使用 tagName 属性返回元素的标记名。区别在于标记名只返回标记名,而节点名返回所有节点(标记、属性、文本、注释)的名称。

该属性是只读的。


浏览器支持

可能值:

  • 返回元素节点的标记名(大写)
  • 返回属性节点的属性名称
  • 返回文本节点的 "#text"
