Form demo on IE9 throws error "AJAX Error 0:.."

When I access form at http://w2ui.com/web/demo/form with IE9 and hit save I get error:

AJAX Error 0: TypeError: Unable to get property 'addEventListener' of undefined or null reference

I have tried with IE9, IE11 with document mode IE9 - gives error. With IE10+ the form works fine.

I have tried with jQuery 1.11 and jQuery 2.0.3.

The documentation requirements shows IE9+, where lies the problem?

Thanks.

Hi, unfortunately i also must use IE9 in some projects, for company directive 😃 btw yes w2ui support IE9 with no problem, in this case IE9 doesn’t recognize the addEventListener of the progress % state in Ajax call, this happen often with IE9, all days i’m fighting with differents problems of compatibility of IE9, because it doesn’t recognize some portion of code if it’s written in a modern way 😃 Like as for example some global declaration of variables.In this case, i just notified today that the problem is at line 13170 untill 13175 just the progress event, there are two solutions.Rewrite that portion of addEventListener in a way that IE9 likes or i think you can also comment that portion of code from 13170 at 13175 but DON’T COMMENT RETURN XHR 😃, Commenting that portion doesn’t affect the right parse of the code just will not display the % state of the ajax call in save but it isn’t a problem.You can use a ajax block ui and unblock ui for the wait.I commented that portion and it work perfectly also in IE9, i notified this problem only with the save of the form object.Hope this help.Bye

Closing this issue, as there are no plans to support IE anymore.
