Question

Answer 1

A:

Have you tried

if (top.document == 'undefined')
{
   top.document = window.top.document || null;
}

Also ive just tested in my chrome browser and top.document returns the actual document so not sure, what version are you using !

Hey, thanks for that, but no go. Version is 5.0.375.55.'window.top' and 'top' are identical. alert() on both yields 'object DOMWindow'. But its 'document' is 'undefined'.Any other thoughts?-swk

Im currently on the same version so I cant understand how your getting undefined. See: http://a.imagehost.org/0651/to_document.png

The JS console is giving me: "Unsafe JavaScript attempt to access frame with URL file; Domains, protocols and ports must match"(not a problem with IE8 or FF)Is this giving anyone a clue as where to look next? Thanks... -swk (robert: thanks for hanging in)

Ok so i think this problem is down to Cross Domain Origin, This is a security precaution taken by browsers to stop your site being manipulated with things such as cookies etc i believe. Somehow you have to tell the frames that they can be access by the parent frame. Here is an article regrading this issue. http://softwareas.com/cross-domain-communication-with-iframes Also try look googel for "Iframes and ajvascript" "Iframes security with cross domain". Also google use a method of making this work with the HTTP-Headers but im not fully sure about that. Im sure this is the problem tho. Regards

So, as I understand that article, the idea is to set the 'top' URL via, “parent.frames[1].location.href=correctURL", after which 'top.document' should then be be able to yield its elements.Hmm. Let me give it a shot, and I'll get back. Thanks, -sk

No dice. The browser goes to an all white screen, and locks up.

Is there other way you can do this without using frames, I also noticed that your awaiting responses on the Google chrome deb team, any response from them yet ?

I wouldn't necessarily mind adopting the scrolling <div> method, and i might yet go that route, but this is really a shortcoming in Chrome. IE8, FF, Safari and Opera pose no difficulty. Here's what I'm doing successfully in those four:frm= top.document.getElementById("frmset"); if ( firefox() ) // etc. { frm.rows= "24.0%, *" ;}

No, nothing yet from the Chrome people. Thanks for hanging in.
