unbind doesn't work if hover uses

[golden]

Please see example page:

​http://goldenman.spb.ru/development/jquery/bug_unbind/

2 span tags has binded mouseover and mouseout handlers. The first of them uses chain of mouseover, mouseout invokes. The second uses hover method to bind handlers. Then for both tags immediately unbinding of mouseout handler invokes. However for first tag it works proper, but for second it doesn't work.

The example page is a broken link so it's difficult to say but this may be related to this ticket about hooking multiple events since hover hooks both mouseout and mouseover.

test case based on how I read the description

[davidserduke]

The test case I created based on the description works for me. If this test case doesn't reflect the actual bug then please reopen ticket with an appropriate test case.

Your test case is not completely proper.

$("#s1").unbind("mouseout");

• this code unbinds all handlers that are binded for this element on this event.

But in my page I tried to unbind only specific handler:

$('#bbb').unbind('mouseout',out); // !!! 2nd parameter important !!!

Please, look on the new sample page:

Ah I see what you mean. Yes that will fail since hover isn't a true event but rather a helper function. There is currently work being done to make what you want to do possible (if it makes it into the core):

I'll leave the bug open for now and hopefully be able to close it soon. :)

The event code has changed so there is now a workaround for this issue. Change

$(...).hover(fnOver, fnOut);

to

$(...).bind('mouseenter.mynamespace', fnOver).bind('mouseleave.mynamespace', fnOut);

That will do the same thing and allow you to namespace the event.
