Position: Add ability to determine if the element is flipped

[T.Lindig]

For my tooltip implementation i need to know, if the positioned element was flipped or better in which direction it is shown. So it would be helpful, if the positions-plugin could add a css marker on his element depending on the calculated position top, left, right or bottom.

In according to the my-option may be a combination of css-classes like this:

ui-position-my-bottom ui-position-my-left

or

ui-position-my-top ui-position-my-right

Providing feedback about the positioning result is definitely a good idea. We've got the using-callback, but that requires to implement the actual positioning to work. We could add a info-only callback, or something like additional classes. The latter poses the difficulty of removing older classes when repositioning.

[T.Lindig]

removing older classes when repositioning is not difficulty, if we remove ever all the additional classes before we repositioning. my be that is not the solution with the best performance, but it would be easy and clean.

#7243 is a duplicate of this ticket.

Design wise this would be extremely useful. For example, in using position on elements that have directional design pieces, such as an arrow. One must know side the positioned element is on.

I mentioned this the other month on the forums too (I must have overlooked this ticket): ​http://forum.jquery.com/topic/position-api-redesign#14737000002025210

Was this ever released? I can't seem to find it anywhere in the code nor documentation..

[Scott González]

As the ticket milestone says, it was released in 1.9.0. It's documented in the ​position API page (see the using parameter) and was fully documented in the ​1.9 upgrade guide. The comment immediately before yours also lists the ​commit in which the code was added.

Ok, found it.. for anyone else ending up here: there's a discussion over at github on why this was reversed.. ​https://github.com/jquery/jquery-ui/pull/390
