如何破壞我自己（被我拖動的div）

Question

$("#b").draggable(); 
$("#map_canvas").droppable({ 
drop: function() { 
    //alert('dropped'); 

    aFn(); 
    } 

Answer 1

$("#map_canvas").droppable({ 
    drop: function(event, ui) { 
     $(this).remove(); // Destroy droppable 
     ui.draggable.remove(); // Destroy draggable 
    } 
});
