Can you please provide a test case ? that is, a small html file with the minimum html/css/js necessary to reproduce the problem.

I'll code one up today and post the link

I made you a sample you can view the bug in a frame at: http://www.armyoffate.com/hoverbug.php

The actual coding is at http://www.armyoffate.com/hoverbug2.php but you can only see the bug in action from the first link.

If you need anything else let me know. Also please let me know once you have a patch or fix for this because this is a huge problem on my site.

Thanks,

Terrence

Also I forgot to mention I found this bug on Firefox 2 & Firefox 3.

I added a menu to the top frame so you can see how each jquery type & version does. It's seperate from the hoverbug2.php frame so it doesn't add any code to it.

//solution :

2405c2405

< while ( parent && parent != elem ) try { parent = parent.parentNode; } catch(error) { parent = elem; }

while ( parent && parent != elem ) try { parent = parent.parentNode; } catch(error) { return false; }

end

in function :

Checks if an event happened on an element within another element

Used in jQuery.event.special.mouseenter and mouseleave handlers

var withinElement = function(event, elem) {

Check if mouse(over|out) are still within the same parent element

var parent = event.relatedTarget;

Traverse up the tree

while ( parent && parent != elem ) try { parent = parent.parentNode; } catch(error) { parent = elem; }

Return true if we actually just moused on to a sub-element

return parent == elem;

};

when you move mouse outside the elem directly to slider ff puts xul element to event.relatedTarget. this causes exception on parent.parentNode (because you cannot access it) so the function returns that slider is inside elem. I'm not sure if this solution works in every case, but cannot find case in with it crashes.

sorry for previous post :P

Solution :

So how would I edit that into my script???

just replace:

 

while ( parent && parent != elem ) try { parent = parent.parentNode; } catch(error) { parent = elem; }

with:

while ( parent && parent != elem ) try { parent = parent.parentNode; } catch(error) { return false; }

in your jquery-1.2.6.js script

see also #4600 for another test case for this bug
