为可放置项添加唯一ID

我有一个小部件,我可以将物品放入垃圾桶.我希望能够在drop事件中为垃圾桶中丢弃的每个项目添加唯一ID.我怎么能这样做,有没有办法让输出值成为列表项的实际名称？谢谢!以下是我的代码:

    $(function() {
    var $gallery = $( "#gallery" ),
        $trash = $( "#trash" );


    $( "li", $gallery ).draggable({
        cancel: "a.ui-icon", 
        revert: "invalid", 
        containment: $( "#demo-frame" ).length ? "#demo-frame" : "document", // stick to demo-frame if present
        helper: "clone",
        cursor: "move"
    });


    $trash.droppable({
        accept: "#gallery > li",
        activeClass: "ui-state-highlight",
        drop: function( event, ui ) {
            deleteImage( ui.draggable );
        }
    });

    $gallery.droppable({
        accept: "#trash li",
        activeClass: "custom-state-active",
        drop: function( event, ui ) {
            recycleImage( ui.draggable );
        }
    });
