Possible Ways to Communicate Between iFrame and Parent Page across domains

Question

Please suggest possible techniques to trigger events in parent page from an iFrame. I tried out url Hashing and using window.postMessage techniques but without any success.

Answer 1

easyXDM is designed for this exact purpose. You can find it at http://easyxdm.net and it has quite a few examples.

To sum it up, it allows two windows to communicate 'freely' using either strings or RPC calls.

See http://consumer.easyxdm.net/current/example/methods.html for one of the RPC-demos.

Answer 2

No success because you cannot for security reasons.
