如果值为0，则不显示选项值

Question

我有jquery jtable，它有动态选项。它工作正常。如果我从下拉列表中选择0，那么它将不会显示表。当第一次加载表时它工作正常。但是当我更新{ {3}}值0未显示的选项。

如果我有除0之外的任何其他数字，那么它将显示。第三行是一个例子。我从下拉列表中选择0它正确更新数据库但不会显示在桌面上。任何人都知道为什么它是否正在发生。我试图加载表但仍无效。

以下是代码。

  $('#cribList').jtable({
                    sorting: true,
                    defaultSorting: 'Number ASC',
                    selecting: true, //Enable selecting
                    multiselect: true, //Allow multiple selecting
                    selectingCheckboxes: true, //Show checkboxes on first column
                    actions: {
                        listAction: 'Rooms.aspx/LoadRoom?database=<%= Request["database"].ToString() %>',
                        deleteAction: 'Rooms.aspx/DeleteRoom?database=<%= Request["database"].ToString() %>',
                        updateAction:  'Rooms.aspx/UpdateRoom?database=<%= Request["database"].ToString() %>',
                        createAction: 'Rooms.aspx/CreateRoom?database=<%= Request["database"].ToString() %>'
                    },

     TypeID: {
              title: 'Type',
              width: '30%',
              inputClass: 'validate[required]',
              options: <%= DisplayRoomOptions() %>
              },

        Stacks:{
                     title:  'Stacks',
                     width: '30%',
                     dependsOn:'TypeID',
                     listClass: 'centerCol',
                     options: function (data)
                         {
                            if (data.source  == 'list')
                             {
                             return <%=appdomain%> +'/Rooms.aspx/GetRoomOptions?TypeID=0';
                             }
                            return  <%=appdomain%> +'/Rooms.aspx/GetRoomOptions?TypeID='+data.dependedValues.TypeID;
                        }   


Code behind

      [WebMethod(EnableSession = true)]
     public static object GetRoomOptions(int TypeID)
            {

                try
                {
                    int[] configRooms = new int[6]; ;

                    if (TypeID == 2)
                       configRooms = new int[] { 0, 1, 2, 3 };
                    else if ((TypeID == 3) || (TypeID == 4))
                        configRooms = new int[] { 0, 1, 2, 3, 4, 5 };
                    else if (TypeID == 1)
                        configRooms = new int[] { 0 };
                    else
                       configRooms = new int[] { 0, 1, 2, 3, 4, 5 };
                    return new { Result = "OK", Options = configRooms };

                }

                catch (Exception ex)
                {
                    return new { Result = "ERROR", Message = ex.Message };
                }

            }

更新代码

 [WebMethod(EnableSession = true)]

 public static object UpdateRoom(GuardRoomData.Room.record)
    {
        try
        {
            record.Save(HttpContext.Current.User.Identity.Name);
            return new { Result = "OK" };
        }
        catch (Exception ex)
        {
            GuardRoomData.Log.WriteError("Save Room (user '" + HttpContext.Current.User.Identity.Name + "'): " + ex.ToString());
            return new { Result = "ERROR", Message = "Save Room failed: " + ex.Message };
        }
    }
