如何确定从 datepicker 中选择/选择的日期是否是假期？

Question

我正在开发一个 asp.net mvc3 项目。我在下面有这张照片，日期为8/29/2016，一定是假期。而且我在我的 SQL Server 2k8 中有一个假期表，所以我的 sql 表中的日期是假期。我想要的是，如果它是假期，天数必须-(minus) the # of holiday，具体取决于申请期间有多少假期。

我在下面有这个代码用于我的开始休假

$("#LSDate").change(function (event) {
    var start = $("#LSDate").val();
    var end = $("#LEDate").val();
    var EmployeeId = $("#hidEmployeeId").val();
    var LeaveTypeId = $("#LeaveType").val();
    saveHalfDay = false;
    saveHalfDayPM = false;
    $("#LeaveIsHalfDay").attr("checked", false);
    if (LeaveTypeId == 3) {
        $.ajax({
            type: "POST",
            url: '../Attendance/_NoDaysApplied',
            data: '&EmployeeId=' + EmployeeId + '&StartDate=' + start + '&LeaveTypeId=' + LeaveTypeId,
            dataType: 'json',
            success: function (response) {
                if (response != null) {
                    $("#LEDate").val(response.msg);
                    $("#txtNoDays").val(response.noofdays);
                    $("#txtNoHrs").val(response.noofdays * 8);
                }
                else {
                    alert("Saving failed. Date Applied exists!");
                    $("#LSDate").val("MM/dd/yyyy");
                    $("#LEDate").val("MM/dd/yyyy");

                    $("#txtNoHrs").val(0);
                }
            },
            error: function (reponse) { }
        });
    }
    else if (end != "MM/dd/yyyy" && end != "") {

                    var dayoff = response.dayoff;
                    var a = $("#LSDate").datepicker('getDate').getTime(),
                    b = $("#LEDate").datepicker('getDate').getTime(),
                    c = 24 * 60 * 60 * 1000,
                    diffDays = Math.round(Math.abs((a - b) / (c)));
                    var days = (diffDays) + 1;
                    var numdays = (days - dayoff);
                    if (a > b) {
                        numdays = 0;
                        alert("End of Leave must be greater than start of leave.");
                    }
                    var hrs = numdays * 8;
                    $("#txtNoDays").val(numdays);
                    $("#txtNoHrs").val(hrs);
                    if ($("#LeaveType").val() == 16) {
                        var url1 = '../BenefitManagement/_SELValidation';
                        var _data1 = '&StartDate=' + $("#LSDate").val() + '&EndDate=' + $("#LEDate").val();

Answer 1

我现在解决了，谢谢。我在js和控制器中创建了一个函数就是它

var txtdy, countholiday;
var nhrs;
function getHolidayCount(EmployeeId, start, end) {
    var isCount = 0;
    var nofhrs = 8;
    var url = '../Attendance/_getHolidayCount';
    var txtday = $("#txtNoDays").val();
    var data = '&EmployeeId=' + EmployeeId + '&StartDate=' + start + '&EndDate=' + end;
    $.ajax({
        type: "POST",
        url: url,
        data: data,
        dataType: 'json',
        async: false,
        success: function (response) {
            isCount = response.isCount;
            countholiday = isCount;
            if (isCount > 0) {
                txtday = txtday - isCount;
                txtdy = txtday;
                nhrs = nofhrs * txtday;
            }
        },
        error: function (reponse) { }
    });
    return isCount;
}

对于控制器

[HttpPost]
    public ActionResult _getHolidayCount(string EmpId, string StartDate, string EndDate)
    {
        //Boolean isTrue = false;
        var isCount = "";

        int empId = Convert.ToInt32(EmpId);
        DateTime Sdate = Convert.ToDateTime(StartDate);
        DateTime Edate = Convert.ToDateTime(EndDate);

        while (Sdate <= Edate)
        {
            if (!(Sdate.DayOfWeek == DayOfWeek.Saturday || Sdate.DayOfWeek == DayOfWeek.Sunday))
            {
                var getHolidayCount = (from a in db.Holidays where a.HolidayDate == Sdate.Date select a.HolidayDate).Count();


                if (getHolidayCount > 0)
                {
                    isCount = Convert.ToString(getHolidayCount);
                }
            }
            Sdate = Sdate.AddDays(1);
        }
        var res = new JsonResult();
        res.Data = new
        {
            isCount = isCount
        };
        return res;
    }

我希望它也能帮助其他人。
