Looks like Twitter and Disqus both use the easyxdm library – http://easyxdm.net/

(I was needing to do this, and google sent me to your site first! Small world…)

Hope so too. I have a workaround now (which has nothing to do with the script, but makes me not have to use it in these cases). thx anyway for this great share and for the quick reply!

I've had multiple reports of issues w/ those 2 browsers (see the comments above). Hopefully I'll find the time to dig into this more soon.

Your script does not seem to work when running IE8 or 7. Hoped your script would give a solution as I was having trouble with this earlyer myself..

In my own case It seems like when trying to access the parentwindow by doing parent.window.postMessage > IE8 will throw an access denied error which I can catch and act upon appropriately. However when trying to send a message to the child window inside an iframe by using document.getElementById("myIframe").contentWindow.postMessage > this will throw no error, though nothing will hapen neither so I am left with an unhandled scenario. Didn't go indepth with your script but a quick test of your demo shows that showing the message from within the iframe works as with my own scenario and the message from the main page to the iframe does not work.

Hi,

I was stuck with IE8 issues on your script. It turned out that IE empties window.location.hash somewhere before it's read. I solved it with a server-side solution.
Thanks for the script. Nice.

I've had a few people complain about IE8 issues. I'll make a note to dig into it when i get a free moment. If you beat me to the solution, let me know. I want to get this figured out.

Hi Josh,

I'm getting "Invalid argument" on this line:

target['postMessage'](message, target_url.replace( /([^:]+://[^/]+).*/, '$1'));

when I am trying to send message from an iframe to parent window (IE8).

Hi Josh.

You did an amazing work. Base on your article I have solved my problem that I asked above. But I tested again your barebones example (http://onlineaspect.com/uploads/postmessage/parent.html) on IE8, it always appear an like me!

Please help!
