从jQuery UI的两倍存在的丢弃事件

Question

我使用jQuery UI的1.7.2非常久远的jQuery 1.3.2

以下脚本导致被触发两次降事件。我尝试了很多的时间，但不能弄清楚为什么？ becouse您使用dropable和排序上相同的选择$（ “列”）

任何建议，为了解决这个问题

$("document").ready(function() { 

    $(".draggable").draggable({ 
     revert: "invalid", 
     helper: "clone", 
     connectToSortable: ".column" 
    }); 

    $(".column").droppable({ 
     accept: ".draggable", 
     drop: function (event, ui) { 
      debugger; 
      var ordinalNo = 1; 
      $(".column .contentObject").each(function() { 
       ordinalNo = ordinalNo + 1; 
      }); 

      var objectId = guidGenerator() + '_' + ordinalNo; 
      var objectType; 
      var contentObjContent = "<div id=\"" + objectId + "\" ><h2>[<span class=\"ordinal\"></span>] "; 

      if (event.srcElement.id === "tableobj") { 
       objectType = tableSource; 
      } 
      else if (event.srcElement.id === "chartobj") { 
       objectType = chartSource; 
      } 
      else if (event.srcElement.id === "textobj") { 
       objectType = textSource; 
      } 

      $.ajax({ 
       url: "/ContentBuilder/ContentObject", 
       data: { 
        viewObjectId: objectId, 
        contentObjectId: null, 
        contentObjectTypeId: objectType, 
        contentObjSourceId: null, 
        ordinal: ordinalNo 
       }, 
       type: "POST", 
       success: function (data) { 
        contentObjContent = data; 
       } 
      }); 
     } 
    }); 
    $(".column").sortable({ 
     connectWith: '.column', 
     handle: 'h2', 
     cursor: 'move', 
     placeholder: 'placeholder', 
     forcePlaceholderSize: true, 
     opacity: 0.4, 
     update: function (event, ui) { 
      changeOrdinal(); 
      if (event.srcElement.id.length <= 0) { 
       updateObjectOrdinals(); 
      } 
     } 
    }).disableSelection(); 

    $(".tablecolumn").sortable({ 
     connectWith: '.tablecolumn', 
     handle: 'h2', 
     cursor: 'move', 
     placeholder: 'placeholder', 
     forcePlaceholderSize: true, 
     opacity: 0.4, 
     update: function (event, ui) { 
      changeColumnOrdinal(); 
     } 
    }).disableSelection(); 
});

。我认为两者都会引发下降。
