Rails spinoffs - Mar 2007 - Sortable: Need ID of moved element

Is it possible for sortable to return the element of the ID that was
moved? The serialize array isn''t good enough, since if two things swap
position I can''t tell which was explicitly moved.

If not, how would you go about this?

Thanks,
Jason

Isn''t that what the onChange callback is about?  I believe it takes the
currently-dragged element as argument, and fires every time it changes 
position during a drag.

OTOH, I believe indeed that onUpdate occurs on drop, only when the 
resulting order changed, and is passed the container element (the one 
you made sortable).  Maybe by combining both you can obtain what you need.

I was under the impression that onChange returned the entire
serialized array every time. You were right and this does exactly what
I need.

Thank you!
