#6754 closed bug (invalid)

a.find(b) produces bad selector if a or b have grouped selectors

Reported by: Phrogz Owned by:
Priority: low Milestone: 1.5
Component: selector Version: 1.4.2
Keywords: find pushstack selector Cc:
Blocked by: Blocking:


$('a,b').find('c,d').selector should produce something like 'a c,a d,b c,b d'. Instead, it produces 'a,b c,d' in jQuery 1.4.2.

This breaks any code that uses the selector for future live-like selections or tests.

Here's a link for a valid jsfiddle test case http://jsfiddle.net/boushley/eJrV5/ I can't speak to the validity of the commits however.

This seems like a better representation of what he's asking: http://jsfiddle.net/SlexAxton/eJrV5/1/

I am not sure jQuery intentionally tries to support comma delimited selectors in a find() statement. It definitely has never supported this, so it isn't a regression, but I consider it something that seems like it should work. Until then, you can just use an add() statement or be explicit.

Here's an updated fiddle that better shows the fact that two different sets are selected. http://jsfiddle.net/boushley/eJrV5/4/

Oops.. I mis-read the description. That .selector property... People need to be made to understand that it's a very rough representation of the selectors that were used and not-at-all "smart".

OK. I think I see what these guys are pointing out. The .selector property is not actually used for the selection, so it's not a good determination of jQuery's support for comma delimited selectors in the 'find' method. In fact, the selection should work just fine (as seen in boushley's fiddle), but the .selector property is just the two selectors concatenated together. It shouldn't be used for testing the final selector that is used.


(Thanks cowboy and boushley)

A couple of points here. One, it's not valid to use a .live() selector after a .find().

DOM traversal methods are not fully supported for finding elements to send to .live(). Rather, the .live() method should always be called directly after a selector, as in the example above. -- http://api.jquery.com/live/

Two, the .selector property is not publicly documented. Don't look at it!
