#7217 closed bug (fixed)

.live and .delegate, multiple handlers

Reported by: b.w@… Owned by: dmethvin
Priority: low Milestone: 1.4.4
Component: event Version: 1.4.3
Keywords: Cc:
Blocked by: Blocking:


Given the code at http://jsfiddle.net/NxjMy/, on clicking 'click me', using jQuery 1.4.2, I get an alert 'foo' and nothing else, but with 1.4.3, I get two consecutive alerts: 'foo' and 'bar'.

This behaviour happens at least with recent versions of Firefox, Google Chrome and Opera. A similar thing happens with .live().

I could not find information about this change in the 1.4.3 release notes. What is going on?

Thanks, Bart

So I am pretty sure the behaviour in 1.4.2 was wrong; return false does not call stopImmediatePropagation and so should not prevent subsequent handlers on the same element from executing. On the other hand, manually calling stopImmediatePropagation does not work to stop subsequent handlers in 1.4.3. So, I’m going to mark this for further review.

The behavior in 1.4.2 is wrong. 1.4.3 behaves correctly here.

OK, thanks, so how do I get the desired behaviour, which is to prevent the second handler from being called?

OK, based on the test case here:


Looks like we need an isImmediatePropagationStopped in liveHandler. I'll put together a patch.

Honor stopImmediatePropagation for live/delegate event handlers. Fixes #7217.
