javascript - jQuery drag and drop - how to get at element being dragged

I am using the jQuery library to implement drag and drop.

How do I get at the element that is being dragged when it is dropped?

I want to get the id of the image inside the div. The following element is dragged:

<div class="block">
    <asp:Image ID="Image9" AlternateText="10/12/2008 - Retina" Width=81 Height=84 ImageUrl="~/uploads/ImageModifier/retina.jpg" runat=server />
</div>

I have the standard dropped function from their example:

$(".drop").droppable({
                 accept: ".block",
                 activeClass: 'droppable-active',
                 hoverClass: 'droppable-hover',
                 drop: function(ev, ui) { }
});

I have tried various ui.id etc. which doesn't seem to work.

Is it not the ui.draggable?

If you go here (in Firefox and assuming you have firebug) and look in the firebug console youll see I am doing a console.dir of the ui.draggable object which is the div being dragged

http://jsbin.com/ixizi

Therefore the code you need in the drop function is

       drop: function(ev, ui) {
                 //to get the id
                 //ui.draggable.attr('id') or ui.draggable.get(0).id or ui.draggable[0].id
                 console.dir(ui.draggable)  
       }
