I have a webpage that features jQuery drag and drop. It works on all desktop browsers but not on iPads. Somehow the click + drag event is captured to move the page up and down.

So, how is drag-and-drop generally done on iPads without 开发者_运维问答writing iPad apps?

You can't use the mouse events ... you need to change to touch events

One way is to divide both code using a mobile Framework, like jQTouch, jQMobile, etc...

Here is a simple test using jQTouch

Just added a simple test of my own

using jQuery UI Sortable for both Browser and iPad

using jQuery UI Sortable demo code and the Touch Events code, works great!
