I don't see any drag & drop jQuery plugin that works in a event delegation way so I put some code together and it works pretty well. Event delegation is good for 2 things:
- Perfomance : Drag & Drop web app are to often too slow. Event delegation could help.
- Simplicity : It's painful to handle events for each elements you have and add during the life of the page.
If you plan to build a complex online webapp, you should take a look on event delegation technics. Hope it will help someone.
