Is it possible to use the $.getJSON from a google Hangout Window. I am trying to do it from a barely modified sample version but I can't get any response from the server. http://pastebin.com/x8jXVceQ#
According to the Same origin policy you can just access a document via AJAX, if it is accessed through the same protocol and TCP port and is stored on the same domain.
If want to access a document from another domain, you can use Cross-origin resource sharing. Therefore the site you want to get via AJAX has to provide the Access-Control-Allow-Origin
HTTP header like:
Access-Control-Allow-Origin: http://hangout.google.com
(You have to replace hangout.google.com
with the actual domain of the Google hangout window)
