droppable prepareOffsets sets incorrect offset when droppable is in an iframe

[reevesm]

version: jquery-ui-1.8.14 browser: chrome os: windows

To reproduce:

1. Create a draggable element using jQueryUI draggable API outside of your iframe
2. Create droppable elements within an iframe (iframe is in middle of the page) on the same page and alert when element is dragged over the droppable within the iframe.

var body = $('#iframe').contents().find('body'); $(body).droppable({

over:function(event,ui) {

alert('over droppable');

}

});

Result: The alert will not fire when dragging over the iframe but will fire when the element is dragged into a position above the iframe

Expected Result: The alert fires when dragging over the body element in the iframe.

See $.ui.ddmanager.prepareOffsets. It appears that m[i].offset is incorrect.

We don't support cross-window dragging.

I had implemented a workaround to enable drag&drop with iframe. in $.ui.ddmanager.prepareOffsets I change the offset to handle the iframe scrolling & the iframe position.

juste after m[i].offset = m[i].element.offset();

  // handle iframe scrolling
  m[i].offset.top -=  m[i].element.parents().find("html,body").scrollTop();
  m[i].offset.left -=  m[i].element.parents().find("html,body").scrollLeft();

  // iframe positioning 
  if( this.current.options.iframeOffset )
  {
    m[i].offset.top +=  this.current.options.iframeOffset.top;
    m[i].offset.left +=  this.current.options.iframeOffset.left;
  }

where iframe offset come from the draggable option like

$( "div" ).draggable({
  iframeFix: true, 
  appendTo: 'body',
  containment: 'window',
  helper: "clone",
  iframeOffset: $("#frame").offset()
 });

Tested on FF 8.0.1 & Chrome 16

Hello Scott.Gonzalez:

I am very much agree with you. I want to say it's working first time as expected. So It should work on 2nd time rendering also.

I am struck in key task. If possible please try to put some focus or guide me.

Thanks Gaurav
