empty（）然后append（）给出一个闪烁的效果

Question

我有这段代码

 $.ajax({
                        type: "POST",
                        url: "display.aspx/getSchedules",
                        data: '{"_facilityID":"' + facilityID + '", "_facilityTime":"' + m + '", "_facilityOffset":"' + os + '", "_facilityClock":"' + FacilityClock + '", "_FacilityDisplayPastEvents":"' + FacilityDisplayPastEvents + '"}',
                        contentType: "application/json; charset=utf-8",
                        dataType: "json",
                        success: function (data) {

                            $("#mySchedule").empty().append(data.d);
                        },
                        error: function (data) {
                            toastr.error("Error in getSchedules");
                        }
                    });

实际上，我从服务器获取数据然后重新绘制表格。重绘是在webMethod中进行的。就在我使用empty（）函数然后为表附加标记，即重绘该表时，该表中突出显示的任何内容似乎都会空白一秒，然后突出显示。

有更好的方法吗？ 感谢

任何对webMethod感兴趣的人都是：

  [WebMethod]
public static string getSchedules(string _facilityID, DateTime _facilityTime, string _facilityOffset, string _facilityClock, bool _FacilityDisplayPastEvents)
{
    if (_facilityID == string.Empty) return string.Empty;
    if (_facilityTime == null) return string.Empty;

    using (Livein5Entities context = new Livein5Entities())  //USING opens/closes db and manages all that for us
    {
        int facilityID = Convert.ToInt16(_facilityID);

        var facility = context.facilities.Where(u => u.FacilityID == facilityID && u.active == true).FirstOrDefault();
        var Facility_location = context.locations.Where(u => u.locationID == facility.locationID).FirstOrDefault();

        DataTable Schedules = getAllSchedules(_facilityID, _facilityTime, _facilityOffset, _FacilityDisplayPastEvents);

        var ScheduleHTML = "<table class='ScheduleTable'>";

        var index = 1;
        foreach (DataRow item in Schedules.Rows)
        {
            DateTime startTime = DateTime.Parse(item[2].ToString());
            DateTime endTime = DateTime.Parse(item[3].ToString());

            startTime = startTime.AddHours(-8);
            endTime = endTime.AddHours(-8);

            ScheduleHTML += "<tr ID='FSID_" + index + "' class='ScheduleItem'>";
            ScheduleHTML += "   <td class='Time'>";
            if (_facilityClock == "24") // Check if the user has selected 24 hours or 12 hours.
            {
                ScheduleHTML += "       <div class='StartTime'>" + startTime.ToString("HH:mm") + "</div>";
                ScheduleHTML += "       <div class='EndTime'>" + endTime.ToString("HH:mm") + "</div>";
            }
            else
            {
                ScheduleHTML += "       <div class='StartTime'>" + startTime.ToString("h:mm tt") + "</div>";
                ScheduleHTML += "       <div class='EndTime'>" + endTime.ToString("h:mm tt") + "</div>";
            }
            ScheduleHTML += "   </td> ";
            ScheduleHTML += "   <td class='Guest'>";
            ScheduleHTML += "       <div class='GuestName'>" + item[4].ToString() + "</div>";
            ScheduleHTML += "       <div class='Topic'>" + item[5].ToString() + "</div>";
            ScheduleHTML += "   </td>";
            ScheduleHTML += "   <td class='EventDetails'>";
            ScheduleHTML += "       <div class='EventName'>" + item[6].ToString() + "</div>";
            ScheduleHTML += "       <div class='Host'>" + item[7].ToString() + "</div>";
            ScheduleHTML += "   </td>";
            ScheduleHTML += "</tr>";

            index++; // Increment The ID Number - Index

        }
        ScheduleHTML += "</table>";

        return ScheduleHTML;
    }
