Draggable Clones Jquery?

Any ideas on how to make the clones draggable?

            $("#draggable").draggable({
                helper: 'clone',
                cursor: 'pointer',
            });

            $("#snaptarget").droppable({
                drop: function(event, ui) {
                       var randomnumber = Math.floor(Math.random()*1000000);
                       var newId = '#draggable_'+randomnumber;

                        $开发者_JAVA技巧(ui.helper).clone(true).removeAttr('id').attr('id',newId).appendTo('#snaptarget');                     
                        $(newId).draggable();                   
                }
            });

$(newId).draggable(); does not work.

You can't start IDs with a #. As you are here:

var newId = '#draggable_'+randomnumber;

It should be:

var newId = 'draggable_'+randomnumber;

Then this:

$(newId).draggable();

should be:

$('#' + newId).draggable();

Example: http://jsfiddle.net/M3UWp/

So you end up with:

var newId = 'draggable_'+randomnumber;
$(ui.helper).clone(true).removeAttr('id').attr('id',newId).appendTo('#snaptarget');  
$('#' + newId).draggable();
