Hi everybody- First time poster, please be gentle. I have written a little rails app where you can create divs and move them around via Thomas'' wonderful dragdrop.js. I would like to be able to fire an AJAX event to update the top and left of the dragged object upon release. I see many AJAX link_to_remote and observe_field. What is the proper way to observe that the position (not content) of a div has changed? I can think of 2 manners, but both seem antiquated compared to the techniques here: 1. put a hidden field inside the div with the top+left, updating these values upon Draggable.finishDrag, triggering an AJAX event 2. Put a whole call to AJAX.Updater inside of a new method of Draggable, called when finishDrag is nearly done. Maybe that''s really 1 manner. In any event, is there a way to extend the Draggable object without modifying dragdrop.js? Can you add more methods via Draggable.prototype? Alternately, if anyone knows of a means to trigger an AJAX event in response to a purely DHTML-type event, please offer a suggestion. thanks, Jason
Override endeffect of the draggable when you create it...
new Draggable(element, {endeffect: yourFunction});

Hi everybody-
First time poster, please be gentle.
I have written a little rails app where you can create
divs and move them around via Thomas'' wonderful
dragdrop.js. I would like to be able to fire an AJAX
event to update the top and left of the dragged object
upon release. I see many AJAX link_to_remote and
observe_field.
What is the proper way to observe that the position
(not content) of a div has changed?
I can think of 2 manners, but both seem antiquated
compared to the techniques here:
1. put a hidden field inside the div with the
top+left, updating these values upon
Draggable.finishDrag, triggering an AJAX event
2. Put a whole call to AJAX.Updater inside of a new
method of Draggable, called when finishDrag is nearly
done.
Maybe that''s really 1 manner. In any event, is there a
way to extend the Draggable object without modifying
dragdrop.js? Can you add more methods via
Draggable.prototype?
Alternately, if anyone knows of a means to trigger an
AJAX event in response to a purely DHTML-type event,
please offer a suggestion.
thanks,
Jason

You''re welcome! I''ve never seen a lick of Ruby, other than Why''s Poignant Guide (love the cartoon foxes). I''m using proto and scriptaculous in a .NET environment. Goes to show you how versatile these scripts are. -----Original Message----- From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org [mailto:rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Jason Kunesh Sent: Friday, February 03, 2006 5:13 PM To: Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org Subject: RE: [Rails-spinoffs] overloading dragdrop.js Thanks, Ryan.
