Node.cloneNode()

The Node.cloneNode() method returns a duplicate of the node on which this method was called.

Syntax

let newClone = node.cloneNode([deep])

node

The node to be cloned.

newClone

The new node, cloned from node.

The newClone has no parent and is not part of the document, until it is added to another node that is part of the document (using Node.appendChild() or a similar method).

deep Optional

If true, then node and its whole subtree—including text that may be in child Text nodes—is also copied.

If false, only node will be cloned. Any text that node contains is not cloned, either (since text is contained by one or more child Text nodes).

deep has no effect on empty elements (such as the <img> and <input> elements).

Example

let p = document.getElementById("para1")
let p_prime = p.cloneNode(true)

Notes

Cloning a node copies all of its attributes and their values, including intrinsic (inline) listeners. It does not copy event listeners added using addEventListener() or those assigned to element properties (e.g., node.onclick = someFunction). Additionally, for a <canvas> element, the painted image is not copied.

To clone a node to insert into a different document, use Document.importNode() instead.
