我想用 jquery 进行拖放。以下是测试代码。但我想要的是将#draggable 拖放到鼠标指向的位置，而不是仅将#draggable 附加到#droppable 中的确定位置。如果有人能提供帮助，我将不胜感激。

<style>#draggable { width: 100px; height: 100px; padding: 0.5em; float: left; margin: 10px 10px 10px 0; }
#droppable { width: 150px; height: 150px; padding: 0.5em; float: left; margin: 10px; }
</style>
<script>
$(function() {
var dropHelp=true
$( "#draggable" ).draggable({
  revert:'invalid',
  helper:'clone',
});
$( "#droppable" ).droppable({
    //   accept:"#draggable",
    //   activeClass: "ui-state-hover",
    //   hoverClass: "ui-state-active",
       drop: function( event, ui ) {
       if(dropHelp){
       //clone and remove positioning from the helper element
           var newDiv = $(ui.helper).clone(true)
           .removeClass('ui-draggable-dragging')
           .css({position:'relative', left:0, top:0});     

       $(this).append(newDiv);

    //drop the draggable source element
    } else {
       $(this).append(ui.draggable);
    }
  }
});
});
</script>
</head>
<body>

<div id="draggable" class="ui-widget-content">
<p>Drag me to my target</p>
</div>

<div id="droppable" class="ui-widget-header">
<p>Drop here</p>
</div>
</body>

您可以删除此行：

//.css({position:'relative', left:0, top:0});

使用这条线，元素在释放时向上跳跃（表现为静态元素）；没有它，它就会被定位在它被释放的地方——“鼠标指向的地方”。
