Hello,
I still have some problems with DragnDrop:
I have a problem with the parameters of a Draggable
new Draggable( 'test', {
onEnd: function( element, target )
{
alert( elelemt );
alert( element.id );
alert( JSON.stringify( element ) );
}
});
When the drag ends I get this messages:
1. Alert: [object Object]
2. Alert: undefined
3. Alert:
{"element":{"_madePositioned":true,"_eventID":2,"_opacity":1},"handle":
{"_madePositioned":true,"_eventID":2,"_opacity":1},"options":
{"handle":false,"zindex":
1000,"revert":false,"quiet":false,"scroll":false,"scrollSensitivity":
20,"scrollSpeed":15,"snap":false,"delay":
0},"dragging":false,"offset":"[3, 13]","delta":"[0, 0]","originalZ":
1000}
Now I have a Droppable:
Droppables.add( 'testDrop' , {
onDrop: function( element, target, event )
{
alert( elelemt );
alert( element.id );
alert( JSON.stringify( element ) );
}
});
When I Drag the Draggable Element on the Droppable I get this Messages:
1.Alert: [object HTMLImageElement]
2. Alert: Test
3. Alert: {"_madePositioned":true,"_eventID":2,"_opacity":1}
I would expect, that the elements i´n both situations are the same.
But they aren't.
I think the second situation is correct....
Where is my error here?
Thanks for your Help,
Stefan Sturm
