I am developing a Ruby-on-Rails-3 website with a few drag-n-drop screens.
Drag-n-drop does not work on all browsers (especially some phones).
Is there an easy way to know whether the web browser supports drag-n-drop, and use an alternative if not? (could be server-side or client-side)
I could use WURFL and check whether pointing_method=touchscreen, but there must be a more Ruby-on-Rails way to do this?
Based on the lack of answers, I guess that the answer is no.
