Make a deep clone in JavaScript while also altering the parent node's type and name

I am looking for guidance on how to clone a Node and then convert its nodeName, ensuring that the attributes are copied along with the children deeply. I want to achieve something similar to switching an existing span element to a div while retaining all its attributes and child elements.

Your help is greatly appreciated!

Once I successfully clone and convert the node to a div, my goal is to replace the original span element with it. Additionally, I am also curious if there is a method to clone all event listeners associated with the element.

Answer №1

This code snippet may not handle text children that are directly under the original span element, but it should function correctly in other cases.

mutantClone = document.createElement("div");
for (var i=0; i<original.childNodes.length; i++){
    var child = original.childNodes[i];
    var childClone = child.cloneNode(true);
    mutantClone.appendChild(childClone);
}
