Can I listen to any cross-domain iframe events?

Are there any events that I can listen in iframes in another domain? For example, enter this page in domain 1:

<html>
<body>
  <iframe src="domain2.com"></iframe>
</body>
</html>

What events can I listen to regarding the contents of an iframe?

Thank!

There are several ways to do this. In new browsers, you can use window.postMessage to communicate between domains between windows (also works for iframes):
