TreeWalker: nextSibling() 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.nextSibling() method moves the current Node to its next sibling, if any, and returns the found sibling. If there is no such node, it returns null and the current node is not changed.

Syntax

js
nextSibling()

Parameters

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,
);
treeWalker.firstChild();
const node = treeWalker.nextSibling(); // returns null if the first child of the root element has no sibling
