Allow removing multiple data keys at once with $.fn.removeData

[rmurphey@…]

I just saw some code in Wijmo that had a string of chained removeData() calls, and it occurred to me there should probably be a way to remove multiple data keys at once. Not sure whether this is a worthwhile addition (I know there are better ways they could have done this to avoid needing to remove one key at a time), but if so, I'd suggest an API that accepts either a string containing a single key (which is what currently works) or an array of keys.

Seems fair. Any desire to write a patch? :D

Yes :) Didn't want to submit one unless it was something people liked.

Sorry, that was me, I wasn't logged in.

We should consider this for 1.7.

Nominating ticket for 1.7 discussion.

+1, Should be consistent with existing API

[jaubourg]

+1, makes sense

[rmurphey]

Per the discussion on the pull request ( https://github.com/jquery/jquery/pull/77) there needs to be a decision as to the API. If we go with a single string, which is consistent with existing APIs ...

$('#foo').removeData('a b c');

... then we make it impossible to remove a key with a space in it. If we go with an array, as I did in the pull request ...

$('#foo').removeData([ 'a', 'b', 'c' ]);

... then we can allow the removal of any valid key, either one or many at a time.

I have no horse in this race; I can see the merits of both solutions.

+1, In favor, but I don't think space-separated by itself is enough.

[ajpiano]

+1, I don't know if we want to break space-separated keys for 1.7 - I like the array, even thought it's "inconsistent" with other aspects of the API

[john]

+1, Let's do this.

[scott.gonzalez]

+1, space delimited string, like everything else

[rwaldron]

Scott, keep in mind that data properties can be any valid string

But then again, we could always just say that strings with spaces are prohibited
