同时需要可拖放ID的jqueryUI的ID [英] Need Id of BOTH draggable and droppable ID's jqueryUI

问题描述

我可以使用下面的代码获取放置的物品的ID，但是如果我尝试更改警报以获取拖动物品的ID，则不会发生任何事情。例如alert（ui.draggable.attr（’id’））;

I can get the id of the item I have dropped on with the below code, but if i try to change the alert to get the id of the dragged item, nothing happens. e.g. alert(ui.draggable.attr('id') );

 $(function() {
             function dropCallback(e) {
              alert("The firing droppable item was " + e.target.id );
                };


        $("#draggable").draggable({axis:"x"});
         var dropOpts = {
          accept:"#draggable",
          drop:dropCallback,
          greedy:true
        };


        $(".target").droppable(dropOpts);
    }); 

推荐答案

尝试使用...

drop:function(event,ui) {alert($(ui.draggable).attr("id"));}
