CAT | postMessage()
Similar to the last example except that this example shows a post happening on another domain.
From John Resig,
“This particular API adds a new method to every window (including the current window, popups, iframes, and frames) that allows you to send textual messages from your current window to any other – regardless of any cross-domain policies that might exist.
Specifically, you’re given a new window.postMessage(“string”) method that generates a message DOM event on the document of the receiving document. This event object contains the message as a property: event.data which the receiving document can use however they see fit.”
