#2122 closed bug (fixed)

Droppable/Draggable element comparison needs to be changed on trunk.

Reported by: mnichols Owned by: paul
Priority: major Milestone: 1.2.2
Component: ui Version: 1.2.1
Keywords: droppable trunk Cc:

Since the rewrite on droppable.js in the trunk, the comparisons within the droppable methods over,out, and drop need to be changed . The component now lets you drop a draggable that is the same element. Please see attached patch. Also note that this patch contains the fixes in #2063 where the ui object is passed to the accept function on droppable.

note that using the patch I attached here, the following is possible in the droppable's accept function:

function tryAccept(ui){

console.debug('draggable:' + ui.draggable); console.debug('droppable:' + ui.instance); console.debug('droppable element:' + $j(ui.instance.element).attr('id')); console.debug('draggable element:' + $j(ui.element).attr('id'));

return true;


This let's the developer do runtime checks on the target droppable to see if an draggable element should be accepted or not. The current args do not allow this easily.

  • Resolution set to fixed
  • Status changed from new to closed

Fixed ('this' now links to the current droppable, first argument is the draggable)
