Document.adoptNode()

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

Syntax

const importedNode = document.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!

Example

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

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