you can use cross document messaging circumvent same origin policy follows.

parent window (site1.com):

var site2 = window.open("http://site2.com"); site2.postmessage("test", "http://site2.com");

child window (site2.com):

function test() {     // code here }  window.addeventlistener("message", function (event) {     if (event.origin === "http://site1.com") {         var funct = window[event.data];         if (typeof funct === "function")             funct();     } }, false);

this simple example. make more sophisticated allow callbacks, return values, etc. require blog post explained.

you may read more window.postmessage on mozilla developer network.
