#8036 closed bug (invalid)

.closest(selectorArray) returns duplicates

Reported by: dmethvin Owned by: dmethvin

Component: traversing Version: git

Blocked by: Blocking: #7340


If an element matches more than one selector in selectorArray, it is returned once for each match. In particular, this causes event.js/liveHandler to erroneously call the same handler multiple times on the same element for a single event.

Looking at the code some more, I wonder if the solution is to de-dup in liveHandler. We definitely don't want to call the handler twice in these cases, it was only attached once.

This is the expected behavior - it returns one match for each provided selector. The only way it'd be called more than once for a single event would be if pass in multiple selectors.

The de-dupe logic should definitely be external to closest in that case, if you need to remove multiple events.

Not an issue, expected behavior.
