How to replace iframe document with another pre-existing document object, without using write()
Question
I just want to replace a blank iframe's document with a pre-existing document object. Not a string of HTML that can use the write() method with (that solution is in many other answers, here) . I just want a document object to replace another document.
My blank iframe:
<iframe src="about:blank" id="myIframe"></iframe>
Routine to replace blank iframe document:
function replaceIframeDoc(objDoc){
var nod_if = document.getElementById("myIframe");
var nod_ifDoc = nod_if.contentWindow.document || nod_if.contentDocument;
nod_ifDoc = objDoc;
}
Document object created, and call to do the replace:
(Note: I encapsulate my document object in a simple object... I need to do that for some other unrelated stuff... just to easily transfer some attributes, etc. Hopefully it's inconsequential to my issue!)
var obj_container = new Object; //just to make easier to do some other stuff
obj_container.document = document.implementation.createHTMLDocument();
obj_container.document.open();
obj_container.document.write("<html>...(some html)...</html>");
obj_container.document.close();
replaceIframeDoc(obj_container.document);

Depending on which browser you need to support, you could do something like this:
var iframe = document.getElementById("myIframe");;
var oldNode = iframe.contentDocument.getElementById("myNode");
var newNode = document.importNode(oldNode, true);
document.getElementById("container").appendChild(newNode);
