Node.parentNode - Web API 接口参考 编辑

概述

返回指定的节点在DOM树中的父节点.

语法

parentNode = node.parentNode

parentNode是指定节点的父节点.一个元素节点的父节点可能是一个元素(Element )节点,也可能是一个文档(Document )节点,或者是个文档碎片(DocumentFragment)节点.

例子

if (node.parentNode) {
  // 从DOM树中删除node节点,除非它已经被删除了.
  node.parentNode.removeChild(node);
}

备注

对于下面的节点类型: Attr, Document, DocumentFragment, Entity, Notation,其parentNode属性返回null.

如果当前节点刚刚被建立,还没有被插入到DOM树中,则该节点的parentNode属性也返回null.
