Cross domain iframe issue
html, javascript, jquery, mootools
Solution
If you don't have control over the framed site, you cannot circumvent the cross-domain policy.
If you have control over both sites, you can use the `postMessage` method to transfer data across different domains. A very basic example:
// framed.htm:
window.onmessage = function(event) {
event.source.postMessage(document.body.innerHTML, event.origin);
};
// Main page:
window.onmessage = function(event) {
alert(event.data);
};
// Trigger:
// <iframe id="myframe" src="framed.htm"></iframe>
document.getElementById('myframe').contentWindow.postMessage('','*');
