Jquery check which element has been dropped

Question

Is there a way to check which .draggable element has been dropped on a .droppable ?

I have a .droppable box and many elements which are .draggable.

I need to make that if an element has been dropped, it can still be dragged, but not dropped again. .droppable triggers an event and if I drop the same object, it triggers it again and I dont want that.

Answer 1

I found a way to see which element has been dropped last and what elements have been dropped alltogether

var lastdropped;
var alreadydropped = new Array();


$( ".droppable" ).droppable({
    drop: function( event, ui ) {
        lastdropped = $(event.srcElement).attr('class').split(' ')[0];

alreadydropped.push(lastdropped);
}
})
