I am coding a webpage to be viewed on iPad. It uses Safaris/Webkits drag & drop. I have exactly copied Safari\'s example drag & drop code but it won\'t work.
I had a similar issue with one of my project but it can be resolved by following tutorial: http://popdevelop.com/2010/08/touching-the-web/ . It works for me I hope you will like it.
Did you read the top of the page you linked to in Apple's documentation? It says:
Note: This technology is supported only on desktop versions of Safari. For iOS, use DOM Touch, described in Handling Events (part of Safari Web Content Guide) and Safari DOM Additions Reference.

I believe you may want to listen for the touchmove and touchend events instead of on drag and on drop. :)
Working alternative :
Firstly, use jquery UI http://jqueryui.com/demos/ for drag and drop functionality
and then add this script https://github.com/furf/jquery-ui-touch-punch for playing it in Ipad or Iphone.
Hope it helps.
