{{ ApiRef("DOM") }}
Document.adoptNode() transfers a {{Glossary("node/dom", "node")}} from another {{domxref("Document", "document", "", "1")}} into the method's document.
The adopted node and its subtree are removed from their original document (if any), and their {{domxref("Node.ownerDocument", "ownerDocument")}} is changed to the current document.
The node can then be inserted into the current document.
adoptNode(externalNode)
externalNode
The copied importedNode in the scope of the importing document.
After calling this method, importedNode and
externalNode are the same object.
[!NOTE]
importedNode's {{domxref("Node.parentNode")}} isnull, since it has not yet been inserted into the document tree!
const iframe = document.querySelector("iframe");
const iframeImages = iframe.contentDocument.querySelectorAll("img");
const newParent = document.getElementById("images");
iframeImages.forEach((imgEl) => {
newParent.appendChild(document.adoptNode(imgEl));
});
Before they can be inserted into the current document, nodes from external documents should either be:
document.adoptNode().For more on the {{domXref("Node.ownerDocument")}} issues, see the W3C DOM FAQ.
