如何動態禁用jQuery datepicker中的特定日期？

Question

我試圖動態禁用數據庫中已經存在的日期（jquery datepicker）。 我已經完成了靜態方法，因為我能夠達到目標，但無法在動態方法中獲得成功

<script language="javascript">
$(document).ready(function () {
    var getfromdb = @Html.Raw(@ViewBag.bookdate);
    var result = '\'' + getfromdb.toString().split(',').join('\',\'') + '\'';
    var disableddates = [result];

    var newdisableddates = ['17/10/2017','18/10/2017','19/10/2017','22/10/2017','23/10/2017','24/10/2017','25/10/2017'];  // Static Approach 

    $("#txtFromdate").datepicker({
        minDate: 0,
        beforeShowDay: DisableSpecificDates,
        dateFormat: 'dd/mm/yy'
    });
    $("#txtTodate").datepicker({
        minDate: 0,
        beforeShowDay: DisableSpecificDates,
        dateFormat: 'dd/mm/yy'
    });

    function DisableSpecificDates(date) {
        var string = jQuery.datepicker.formatDate('dd/mm/yy', date);
        return [disableddates.indexOf(string) == -1];
    }
});

這是我的控制器代碼：

    List<string> getbookdate = new List<string>();
    getbookdate = BookDate(id);
    ViewBag.bookdate = JsonConvert.SerializeObject(getbookdate.ToList());


     public List<string> BookDate(int? id)
        {
            DateTime dt = System.DateTime.Now.Date;
            var getbookdate = (from x in entity.BookingMasters
                               join
                               y in entity.BookingDetails on x.BookingId equals y.BookingId
                               where x.ProductId == id && y.FromDate > dt && y.ToDate > dt
                               select new BookingModel { ProductId = x.ProductId.Value, FromDate = y.FromDate.Value, ToDate = y.ToDate.Value }).ToList();

            List<string> allDates = new List<string>();

            foreach (var r in getbookdate)
            {
                for (DateTime date = r.FromDate; date <= r.ToDate; date = date.AddDays(1))
                {
                    allDates.Add(Convert.ToString(date.ToShortDateString()));
                }
            }
            return allDates;
        }

禁用不適用於日期選擇器。 試試我的plnkr。

https://embed.plnkr.co/h4RaeIKJVfj9IjyHREqZ/

它獲取單擊時的日期選擇器，並解析給定的日期和數據集，如果找到匹配項，它將刪除其上的click事件。 並在每個渲染器上重復，請參見我的plnkr html鏈接。 希望能幫助到你

您最初的想法是朝正確的方向發展，但是我認為所有字符串轉換可能都有些奇怪。 我只是經過日期並與日期進行比較，而不是與所有繁瑣的東西進行比較：我已經編寫了此快速測試...

控制器：

//Replace with however you get dates
 ViewBag.DatesList = new List<DateTime>() 
    { 
        new DateTime(2018, 01, 01), 
        new DateTime(2018, 01, 02), 
        new DateTime(2018, 01, 03) 
    };
    return View();

視圖：

<script language="javascript">
$(document).ready(function () {

var disableddates = [];
@foreach (DateTime date in ViewBag.DatesList)
{
    //note JS month is zero-based for no good reason at all... 
    @:disableddates.push(new Date(@date.Year, @date.Month-1, @date.Day))
}

$("#txtFromdate").datepicker({
    minDate: 0,
    beforeShowDay: DisableSpecificDates,
    dateFormat: 'dd/mm/yy'
});
$("#txtTodate").datepicker({
    minDate: 0,
    beforeShowDay: DisableSpecificDates,
    dateFormat: 'dd/mm/yy'
});

function DisableSpecificDates(date) {
    //filter array to find any elements which have the date in.
    var filtereddates = disableddates.filter(function (d) {
        return d.getTime() === date.getTime();
    });

    //return array with TRUE as the first (only) element if there are NO 
    //matching dates - so a matching date in the array will tell calling 
    //code to disable that day.
    return [filtereddates.length == 0];
}
});
</script>

這似乎為我工作。
