TreeWalker: parentNode() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The TreeWalker.parentNode() method moves the current Node to the first visible ancestor node in the document order, and returns the found node. If no such node exists, or if it is above the TreeWalker's root node, it returns null and the current node is not changed.

Syntax

js
parentNode()

Parameters

None.

Return value

A Node object or null.

Examples

js
const treeWalker = document.createTreeWalker(
  document.body,
  NodeFilter.SHOW_ELEMENT,
  {
    acceptNode(node) {
      return NodeFilter.FILTER_ACCEPT;
    },
  },
  false,
);
const node = treeWalker.parentNode(); // returns null as there is no parent
