Testing framesets and opening top page accordingly with JavaScript

Hi there,

I'm having a bit of difficulty with a function that will open a link
depending on the calling frameset.
The function (promoLink()) is located in a frame
(trinity.getminted.com) and depending on the frameset
(www.instanwinmirror.com or www.sundaymailinstantwin.com) I wish to
open the link www.instantwincasino.com and www.sundaymailcasino.com
respectively.

I am having trouble testing the properties of the frameset, I have
tried the following and javaScript does not seem to recognise them as a
string.

function promoLink()
{

if (parent.topFrame.location.href = ...
if (top.location.href=..
if (window.top.document.location.href=..

}

I'd appreciate any pointers! Thanks in advance for looking.

You can't. The reason you can't is that you can't read the location
property of the parent frameset due to cross domain security restrictions.

It should give you a Security Warning or something to that effect if the
page that promoLink is in is from a different domain than the frameset.

Oh thanks Randy..
Is there no way of getting around it then? No way of getting
top.location.href or something?

I would have thought this problem would be quite common, particularly
with white label sites that wish to link to different URLs depending on
the domain

thanks for your help

No, it is a security issue. Look at the flip side. Would you want me to
be able to put your bank's website in a 100% wide/high IFrame and read
data from it?

It is very common and the solution is the same - you can't from the client.
