Normally, scripts on different pages are allowed to access each other if and only if the pages they originate from share the same protocol, port number, and host. Above error message shows that you can't access an < iframe > with different origin using JavaScript/jQuery, it would be a huge security flaw if you could do it.

window.postMessage() provides a controlled mechanism to securely circumvent this restriction.
