Jquery始终还原可拖动对象有效

Question

我有一个拖放示例,它将可拖动对象恢复到它在可放置div中的原始位置.

我的问题是,当我的可拖动对象上的revert有效时,我能够将对象拖到页面上的不同位置,我的可拖动对象只有当我将它们放入droppable div时才会恢复.

我希望我的可拖动对象可以恢复,无论您将它们拖到页面的哪个位置？

我试过这个有效但不起作用.

{
revert: 'vaild',
stop: function(){
    $(this).draggable('option','revert','invalid');
}

我的问题在于,当我将它们放入droppable div时,我的可拖动对象会恢复但不会恢复.

  <script>
        $(function() {
        $( "#draggable" ).draggable({ revert: "valid" });
        $( "#draggable1" ).draggable({ revert: "valid" });
        $( "#droppable" ).droppable({
        activeClass: "ui-state-hover",
        hoverClass: "ui-state-active",
        drop: function( event, ui ) {
        var dragElemId = ui.draggable[0].id;
        var imgPath = $('#' + dragElemId).attr("des-image");
        $( this )
            .find( ".drop-image" ).removeAttr("src").attr("src",imgPath);
        }
        });
        });
        </script>

将revert属性设置为true将使它们始终还原.

   $( "#draggable" ).draggable({ 
       revert: true
   });
   $( "#draggable1" ).draggable({ 
       revert: true
   });
   $( "#droppable" ).droppable({
        activeClass: "ui-state-hover",
        hoverClass: "ui-state-active",
        drop: function( event, ui ) {
             //ommited for brevity
        }
    });
