Submit event on a form element not unbound properly in IE

[gethinw]

Submit events are not unbound fully from form elements in Internet Explorer. Would appear to be because jQuery.event.special.submit.setup (2199 in 1.4.2 source) is only applied if the element in question isn't a form, whereas the teardown function (2222) gets applied regardless, therefore not removing the standard submit event.

Could you submit a valid test case for us to see where this is breaking?.

[gethinw]

OK - found an interesting twist on this while putting together a test case:

Bug is as previously described in ​http://fiddle.jshell.net/kytmD/2/ - if you 'Bind' then 'Unbind' then submit the form, an error will occur.

However, if the JS is run on load ('$(window).load(...)') rather than onReady ('$(...)') - ​http://fiddle.jshell.net/kytmD/1/ - the error doesn't occur. This would appear to be a side-effect of the fact that attaching a load event to the window creates an object in $(window).data('events'), the lack of which (at line 1919) causes the error in the other case, but as far as I can tell the handle function (1904) shouldn't be being called at all, so this is a coincidence rather than a fix.

Resetting milestone to future.

I think I've fixed this IE8 bug in my 1.7 branch, I'll confirm later this month when it lands.

This is fixed as a result of the event rewrite in 1.7.
