Question

我有三个按钮，我想将它拖放到droppable div中，但它不起作用。请查看我的代码并建议我最好

<body>
   <form method="post" action="Dashboard.aspx" id="form1">
   <script type="text/javascript">

      $('#play1').draggable();
      $('#Yasin2').draggable();
      $('#page3').draggable();
      $('#page24').draggable();

      $('#divScene').droppable({
      drop: function (event, ui){
      var ID = $(ui.draggable).attr('id');
      alert(ID);
      }
   });
  </script>

  <div>
    <input type="submit" name="btnAddScene" value="Add" id="btnAddScene" style="float:right; height: 26px;">
     <h1>Scene(s)</h1>
  </div>

  <div id="divScene" class="ui-droppable" style="border-style:solid; border-width:5px; padding:20px 20px 20px 20px;">
<input type="button" class="ui-draggable" name="play1" value="play" onclick="return false;__doPostBack('play1','')" id="play1" class="ui-widget ui-state-default ui-corner-all" title="Scene">
<input type="button" class="ui-draggable" name="Yasin2" value="Yasin" onclick="return false;__doPostBack('Yasin2','')" id="Yasin2" class="ui-widget ui-state-default ui-corner-all" title="Scene">
<input type="button" class="ui-draggable" name="page3" value="page" onclick="return false;__doPostBack('page3','')" id="page3" class="ui-widget ui-state-default ui-corner-all" title="Scene">
<input type="button" class="ui-draggable" name="page24" value="page2" onclick="return false;__doPostBack('page24','')" id="page24" class="ui-widget ui-state-default ui-corner-all" title="Scene">
   </div>

  </form>
 </body>
</html>

首先，您需要在页面中包含jQuery和jQuery UI：

<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>

之后，您需要将jQuery代码包装在 DOM ready 处理程序$(function() {...});中，以确保在执行jQuery代码之前已正确加载所有DOM元素：

<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script>
    $(function () {
        $('#play1').draggable();
        $('#Yasin2').draggable();
        $('#page3').draggable();
        $('#page24').draggable();

        $('#divScene').droppable({
            drop: function (event, ui) {
                var ID = $(ui.draggable).attr('id');
                alert(ID);
            }
        });
    });
</script>

错误是可拖动的，并且droppable不能在按钮上工作，它仅适用于div。

jquery拖放不工作请查看我的代码
