dojo环境中的jquery：无法刷新date.picker

Question

您好我在dojo环境中刷新jquery.datepicker时遇到了问题。

在通过request.post获取json（测试的日期和数量）之后，我将结果json强制转换为数组对象。我叫函数 - “$（”＃Hour“）。datepicker（”refresh“）;”什么都没发生请参阅下面的代码： -

var arrDatesNTests = [];

function checkavailableDates(mydate)
{
     var $return=false;// set all dates disenable 
     var $returnclass ="unavailable";
     $checkdate = $.datepicker.formatDate("yy-mm-dd", mydate);
     for(var i = 0; i < arrDatesNTests.length; i++)
         {    
             if(arrDatesNTests[i] == $checkdate)
             {
                 $return = true;// enable specified dates only
                 $returnclass= "available";
             }
          }
          return [$return,$returnclass];
}

$(function() 
{
    $("#Date").datepicker
    ({
        dateFormat: "yy-mm-dd",
        numberOfMonths: 1,
        onSelect: function( selectedDate ) 
        {
            // later add function for hourpicker
        },
        beforeShowDay: checkavailableDates,
     });
});

on(selectBatches, 'change', function(valueBatch)
{
    window.winBatch = valueBatch;
    pause.show();// cause the main container to be on standby
    request.post('list_dates.php',
    { data:{nameDB : (window.winDB), nameCard : (window.winCard), selectedBatch :  
       valueBatch}, handleAs: "json"
    }).then
    (
        /*//result
        response ={"msg":[
        {"date":"2012-03-26","numTests":"857"},
        {"date":"2012-03-27","numTests":"470"},
        {"date":"2012-03-28","numTests":"544"},
        {"date":"2012-03-29","numTests":"618"}]}
        */

         function(response)
         {   try
          {    if(response.msg)
                 {   
                      arrDatesNTests = (response.msg);
                      $("#Hour").datepicker("refresh");
                      pause.hide();
                 }
                else
                {
                      pause.hide();
                      var errormsg = (response.errmsg +"\r\n"+ response.errcode);
                      throw new Error(errormsg);
                 }
           }

          catch(e)
          {
              pause.hide();
              errDlg(""+e+"");
          }
         }
    )

});

请指教。 提前谢谢。
