You could also use jQuery data() like this.. if ($(elem).data(‘draggable’)) { alert(“yes”); } else { alert(“no”); } if ($(elem).data(‘fooable’)) { alert(“yes”); } else { alert(“no”); } See it here: http://bootply.com/60153
I found that Keith’s method worked for me. Since his answer doesn’t include an example implementation, I’ll post mine: $(‘.dropTarget’).droppable({ drop: function(ev, ui) { var dropped = ui.draggable; var droppedOn = $(this); $(dropped).detach().css({top: 0,left: 0}).appendTo(droppedOn); } }); or, slightly more concisely: $(‘.dropTarget’).droppable({ drop: function(ev, ui) { $(ui.draggable).detach().css({top: 0,left: 0}).appendTo(this); } });
