Access parent window from iframe (cross-domain)

If I were you I would check out window.postMessage. It may do what you want:

For reference see the following:

• MDN - Window.postMessage
• https://stackoverflow.com/a/3076648/296889 - see the Window.postMessage section

If I understand correctly, all modern browsers do now allow to do this. So I'm here to find the best solution.

This is your solution. What you're asking is not possible.

EDIT

As mentioned in the comments below, @JeremysAwesome's answer offers a method that would allow cross-domain requests under certain circumstances. See the SO question below for more information.
