JSON serialize a DOM element

Question

If I do:

var el =
{
   o : document.createElement(\"iframe\")
}

var fs = JSON.stringify(el);

and then I try to access with

var ofs = JSON.parse(fs);

JSON (JavaScript Object Notation) is not designed for serializing DOM Nodes, you'll need to pull out the stuff you want by yourself and write it to an object, and then re-create the DOM Nodes from that if you need.

In fact, Chrome doesn't even execute your code:

TypeError: Converting circular structure to JSON
