JQuery .sortable() not functioning using WebWorks for PlayBook


Most of jQuery functionality I have played with is supported, I however am I unable to use .sortable().

Following is the code:




$(document).ready(function() {
  $(function() {
  $("#content ul").sortable();



The result was tested in Firefox, Chrome and Safari. On the Simulator, clicking on the <li> items does nothing while dragging it moves the page up and down rather than moving the elements.


Simulator version 0.9.2 jQuery version 1.5(also tested with 1.3.2, no luck).


I have seen the SketchPad Example, and document.ontouchmove, but hope this is achievable using only jQuery, for higher cross compatibility.

Any help would be appreciated.

This would be nice but I don't think any touch device supports jQuery sortable.

Re: JQuery .sortable() not functioning using WebWorks for PlayBook

Suppose you have a canvas with an id of 'mycanvas'.  Try the following:


$('body').delegate('#mycanvas', 'touchstart', function(e){


 var x = e.originalEvent.changedTouches[0].pageX - $(this).offset().left;
 var y = e.originalEvent.changedTouches[0].pageY - $(this).offset().top;
 //x and y are the points of the canvas for the event




You can also use 'touchend' and 'touchmove' in addition to 'touchstart'.


If you are using the latest version of JQuery, then you should be fine; however, earlier versions do not have the delegate function, so use bind or live functions instead.


Just as a note, this will probably only work on an actual touch screen device.  In the SketchPad tutorial, I believe mousevents are used to emulate this behavior.  I tested similiar code on an actual android device, which is also webkit based like the playbook.
