Document: adoptNode() 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.

Document.adoptNode() transfers a node from another document into the method's document. The adopted node and its subtree are removed from their original document (if any), and their ownerDocument is changed to the current document. The node can then be inserted into the current document.

Syntax

js
adoptNode(externalNode)

Parameters

externalNode

The node from another document to be adopted.

Return value

The copied importedNode in the scope of the importing document.

After calling this method, importedNode and externalNode are the same object.

Note: importedNode's Node.parentNode is null, since it has not yet been inserted into the document tree!

Examples

js
const iframe = document.querySelector("iframe");
const iframeImages = iframe.contentDocument.querySelectorAll("img");
const newParent = document.getElementById("images");

iframeImages.forEach((imgEl) => {
  newParent.appendChild(document.adoptNode(imgEl));
});
