IE9 responds with data undefined

[kazuo]

Hello, I'm using xdomain 0.7.3 and unable to get it working on IE9. I'm using the simple settings of defining master and slave inline with the script. I tested it against Chrome (with xdomain.debug = true) to ensure xdomain is being used and configured correctly.

What's happening in IE9 is after doing a GET request, accessing the response data via Javascript comes back undefined. The GET request does respond back with a 200 with a response body of the expected data. It doesn't seem like it's passing the data.

I looked at the security settings in IE9 seeing if it has something to do with iFrames. I changed two settings under Tools > Internet Options > Security > Custom Level... > Miscellaneous:

• "Access data sources across domains" switched to Enable
• "Navigate windows and frames across different domains" to Enable

Please let me know if any more information is required for clarity. Thanks!

Edit: I went back a few versions to see if there are any working versions for my app. I found that 0.6.17 has the data from the response instead of undefined. I haven't had a chance to fully test 0.6.17, but at the very minimum, 0.6.17 has the expected data and starting at 0.7.0 it has undefined data.

Hi Rey, can you run through the FAQ in the README and report back?

The same situation has occurred. (I use ajax library jQuery v2.2.3)

Here's the debug output:

xdomain (http://localhost:49704): proxying request to slave: 'http://~' xdomain (http://localhost:49704): creating iframe xdomain-3b97f78b xdomain (http://localhost:49704): new socket: xdomain-2627a7bb xdomain (http://localhost:49704): receive socket: xdomain-2627a7bb: ready xdomain (http://localhost:49704): send socket: xdomain-2627a7bb: request xdomain (http://localhost:49704): receive socket: xdomain-2627a7bb: XD_CHECK -> [object Object] xdomain (http://localhost:49704): send socket: xdomain-2627a7bb: ready xdomain (http://localhost:49704): ready socket: xdomain-2627a7bb (emit #1 pending) xdomain (http://localhost:49704): receive socket: xdomain-2627a7bb: xhr-event -> readystatechange xdomain (http://localhost:49704): receive socket: xdomain-2627a7bb: xhr-event -> readystatechange xdomain (http://localhost:49704): receive socket: xdomain-2627a7bb: response xdomain (http://localhost:49704): send socket: xdomain-2627a7bb: close xdomain (http://localhost:49704): close socket: xdomain-2627a7bb

It seems IE8/9 are different from the others in xhr event's occurence.

• "onload" and "onreadystatechange"(order: "onreadystatechange" -> "onload") in IE9(maybe IE8)
• only "onload" in the others
