datepicker 的代码
$("#datepicker td").attr("class","datetimetd");
     
      $(".datetimetd a").hover(
          function () {
//            alert("here");
             needmove=0;
            $(this).addClass("hover");
            var year=$(".ui-datepicker-year").html();
            var month=$(".ui-datepicker-month").html();
//            alert($(this:first).html());
//            var day=$(this).find("a").html();
            var day=$(this).html();
            var date=year+"-"+month.replace("月","")+"-"+day;
            
            var webUrl=$("#url").val();
            var currentUser=$("#currentUser").val();            $.ajax({
            type:"POST",
            url:"http://zengjf/RainLanderWeb/GetEventList.aspx/GetEventList.aspx",
            data:{key:date,webUrl:webUrl,currentUser:currentUser},
            success:function(msg)
             {
//             if(msg!=""){
             $("#enventList").html(msg);
             $("#Control").css("position","absolute");
             $("#Control").css("left",x);
             $("#Control").css("top",y);
             $("#Control").css("display","block");
             needmove=1;
//             }
//             else
//             {
//             needmove=1;
//             }
//             alert("success");
             }
            });          },
          function () {
//            $("#Control").css("display","none");
