I need to inject in an iframe window a document object that I instanciated previously, and I cannot serialize it into a string or a remote url (those are solutions proposed on previous stackoverflow posts), because elements of this document objects are bound to other objects in my code.

How can I do it ?

thanks, b.

  • 1 can you instanciate document object already inside iframe? – Eldar Djafarov Commented Aug 31, 2009 at 11:14
  • I have no clue what in the world your question is here. Wondering if I am the only one. – epascarello Commented Aug 31, 2009 at 11:34
  • Djko : well that was the last solution I was thinking of: instanciating the object inside the iframe and then modify it, finally inject iframe in main document. I wanted to make sure that I was not missing something. – Benoît Pointet Commented Aug 31, 2009 at 11:45
  • epascarello : in other words : to put a document in a window you have to give the url for it, or when your document is already locally in a string, then you can write into the window this string. But when your document is a document object, loaded "in the background" through some XmlHTTPRequest and transformed, linked, ..., then HOW CAN YOU INJECT IT INTO A WINDOW OR IFRAME ? – Benoît Pointet Commented Aug 31, 2009 at 11:48

Reset to default 7

Try using importNode:

/* Change these: */
var documentToCopy = document,
    iframeDocument = iframe.contentWindow.document;

/* Replace current document-element (<html>) with the new one: */
iframeDocument.replaceChild(
    iframeDocument.importNode(documentToCopy.documentElement, true),
    iframeDocument.documentElement
);

See https://developer.mozilla/en/DOM/document.importNode
