亲自试一试 »

页面下方有更多实例。


定义和用法

parentElement 属性返回指定元素的父元素。

parentElement 和 parentNode 之间的区别在于,如果父节点不是元素节点,parentElement 将返回 null:

document.body.parentNode; // 返回 <html> 元素
document.body.parentElement; // Returns the <html> element

document.documentElement.parentNode; // 返回文档节点
document.documentElement.parentElement; // 返回 null(<html> 没有父 ELEMENT 节点)

在大多数情况下,使用哪个属性并不重要,但是,parentNode 可能是最受欢迎的。

该属性是只读的。
