jQuery AJAX调用在服务器端不起作用

Question

我在ASP.Net中有一个jQuery AJAX webmethod，在本地测试时工作得很好。但是当上传到服务器时，有时它有时不起作用。当我用萤火虫调试代码时，我看到webmethod被调用，但立即跳到ajax脚本的错误部分。这是我的第二个星期的研究，我仍然无法找到任何帮助我。

jQuery代码：

<script type="text/javascript"> 
    $(document).ready(function() { 
     //get current date 
     var _currdate = new Date(); 
     var currday = _currdate.getDate(); 
     var currmonth = _currdate.getMonth() + 1; 
     var curryear = _currdate.getFullYear(); 
     var currdate = curryear + "-" + currmonth + "-" + currday; 

     //on page load event, check to see if employees are added to the schedule 
     $.ajax({ 
      type: "POST", 
      url: "Schedule.aspx/GetSchedule", 
      data: '{"FinancialDate" : "' + currdate + '"}', 
      contentType: "application/json; charset=utf-8", 
      dataType: "json", 
      success: function (data) { 
       $('#timepanel').append(data.d); 
       $('.schslider').each(function() { 
        //check employee checkboxes if schedule exists 
        if ($('.schslider').length > 0) { 
         $('input#chk' + $(this).attr('id')).attr('checked', true); 
         $('input:checkbox:checked').parent('label').addClass('selected'); 
         empcount = $('input:checkbox:checked').length; 
         $('#emplistddl').text("Liste d'employés (" + empcount + " Employés Selectionnés) | Employees' List (" + empcount + " Selected Employees)"); 
        } 
        //get the values for the slider 
        var startvalue = $('span#' + $(this).attr('id') + 'start').text(); 
        var endvalue = $('span#' + $(this).attr('id') + 'end').text(); 
        startvalue = (parseInt(startvalue.substring(0, 2), 10) * 60) + parseInt(startvalue.substring(3), 10); 
        endvalue = (parseInt(endvalue.substring(0, 2), 10) * 60) + parseInt(endvalue.substring(3), 10); 
        $('span#' + $(this).attr('id') + 'start').remove(); 
        $('span#' + $(this).attr('id') + 'end').remove(); 
        $(this).slider({ 
         range: true, 
         min: 480, 
         max: 1380, 
         values: [startvalue, endvalue], 
         step: 5, 
         slide: function (event, ui) { 
          var minutes0 = parseInt(ui.values[0] % 60); 
          var hours0 = parseInt(ui.values[0]/60 % 24); 
          var minutes1 = parseInt(ui.values[1] % 60); 
          var hours1 = parseInt(ui.values[1]/60 % 24); 
          var time = getTime(hours0, minutes0) + ' - ' + getTime(hours1, minutes1); 
          $(this).parent('div').children('span#' + $(this).attr('id') + 'timestamp').text(time); 
          var total = parseFloat((hours1 + (minutes1/60)) - (hours0 + (minutes0/60))); 
          $(this).parent('div').children('span#' + $(this).attr('id') + 'total').text(total.toFixed(2) + ' hrs'); 
         } 
        }); 
       }); 
      }, 
      error: function (e) { $('#loaderrorboxtimepanel').removeClass('hidebox').addClass('showbox'); } 
     }); 
</script> 

将WebMethod代码如下：

<WebMethod(True)> _ 
    Public Shared Function GetSchedule(ByVal FinancialDate As String) As String 
     Dim StoreNumber_ForWebMethod As String = ConfigurationManager.AppSettings("StoreNumberKey") 
     Dim _SqlConnection As New SqlConnection("Data Source=INTRIS;Initial Catalog=*****;User ID=sa;Password=*****") 
     Dim _SqlDataAdapter As New SqlDataAdapter("select h.magasin, h.employe, e.nom, h.datefinancier, h.debut, h.fin, h.totalheure, h.annee, h.semaine, h.evenement, h.etat, h.breakstart, h.breakend " _ 
               & "from web.dbo.hours h , web.dbo.employee e " _ 
               & "where h.employe = e.numero and h.magasin = " & StoreNumber_ForWebMethod & " and h.datefinancier = '" & FinancialDate & "'", _SqlConnection) 
     Dim _DataSet As New DataSet 
     Dim ScheduleBuilder As String = Nothing 

     _SqlDataAdapter.Fill(_DataSet, "Schedule") 

     If Not _SqlDataAdapter Is Nothing Then 
      If _DataSet.Tables("Schedule").Rows.Count > 0 Then 
       For i As Integer = 0 To _DataSet.Tables("Schedule").Rows.Count - 1 
        ScheduleBuilder += "<div id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "timecontainer' class='timecontainer'>" _ 
            & "<span id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "start'>" & _DataSet.Tables("Schedule").Rows(i).Item("debut").ToString & "</span>" _ 
            & "<span id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "end'>" & _DataSet.Tables("Schedule").Rows(i).Item("fin").ToString & "</span>" _ 
            & "<label>" & StrConv(_DataSet.Tables("Schedule").Rows(i).Item("nom").ToString, VbStrConv.ProperCase) & "</label>" _ 
            & "<span id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "timestamp' class='timestamp'>" & _DataSet.Tables("Schedule").Rows(i).Item("debut").ToString & " - " & _DataSet.Tables("Schedule").Rows(i).Item("fin").ToString & "</span>" _ 
            & "<span id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "total' class='total'>" & _DataSet.Tables("Schedule").Rows(i).Item("TotalHeure").ToString & " hrs</span>" _ 
            & "<div id='" & _DataSet.Tables("Schedule").Rows(i).Item("employe").ToString & "' class='schslider'></div></div>" 
       Next 
      End If 
     End If 

     Return ScheduleBuilder 
    End Function 

任何帮助，将不胜感激

更新 是JSON和webMethods compati与SQL Server 2000兼容？

首先，我想感谢@patmortech通过展示我什么是错误指导我在正确的方向。 一旦我发现，使用Firefox的Firebug的调试问题，这是一个单引号失踪

Dim _SqlDataAdapter As New SqlDataAdapter("select h.magasin, h.employe, e.nom, h.datefinancier, h.debut, h.fin, h.totalheure, h.annee, h.semaine, h.evenement, h.etat, h.breakstart, h.breakend " _ 
              & "from web.dbo.hours h , web.dbo.employee e " _ 
              & "where h.employe = e.numero and h.magasin = **'" & StoreNumber_ForWebMethod & "'** and h.datefinancier = '" & FinancialDate & "'", _SqlConnection) 

，因为它是一个字符串。

问题解决了:)
