I have a website(abc.com) in which a iframe(efg.com) is opened in a facebox.i have used porthole to do a java-script cross domain scripting, but this is working fine in chrome but not in firefox and internet explorer.
is there any other way to send a message in a cross domain environment using javascript?
Try Apache url rewrite
I also experienced same issues using porthole, I can't send message event from child iframe to the parent page on firefox and IE, the problem is that my iframe code doesnt have a name attribute only id, so I added a name attribute to my iframe and viola! it now works on firefox and IE now!.
Please make sure your iframe will have a name and ID. :)
