Just noticed this issue in Firefox 3.6.19 also. This code was working fine on 1.4.2 as far as I can recall, however since upgrading to 1.6.1 and 1.6.2, the issue has arisen.

I have a form validation class which uses the required="required" attribute in conjunction with $(obj).attr('required') and it's now returning "undefined".

Any ideas when this will be addressed? Looking at releasing this app as a private beta next month. Would love to be running 1.6.2 but will downgrade to 1.4.2 if necessary.

Thanks guys!

Just double checked this in Chrome and a few other browsers and they seem to be operating fine. Definitely a Firefox 3.6.x issue.

I am seeing this in Firefox 3.6 as well. The behavior is not consistent with what happens in IE7, IE8, and Chrome. Have not had a chance to test it with other browsers.

Would definitely like to see this fixed in 1.6.3
