IE8上的Ajax / PHP问题

While working on a web application for a client I have stumbled on a bit of a paradox. The application is PHP/Ajax and we've tested it on all major browsers, including IE7-IE8.

However a client who has windows7 and I believe has IE8 is getting the error message below, and the application hangs, but when I use it on IE, Firefox and Chrome its fine.

Could this be down to a security issue on the browser that we could change the setting on as Their IE8 and my IE8 aren't matching up.

Ok, after typing in the url in that screen-shot (URL ), I was able to find the offending code. Line 112 of that file (as indicated by the error) is:

$('#regGenderM').remoteAttr('checked','checked');

Now, it's easy to see the error here. It should be removeAttr instead of remoteAttr...

Make that change, and you should be golden.
