为什么不向新请求的数据加载数据表？

Question

为什么数据表不刷新？我发送参数并调用get，它将在第一次而不是第二次加载数据，即不是新数据。它确实调用存储过程并获取数据，但数据表从未刷新。为什么？

var url = '@Url.Action("ServicesDetailedReportPartyWise")';
var data = { FromDate: $("#FromDate").val(), ToDate: $("#ToDate").val(), PartyName: $("#PartyName").val() }
       $.post(url, data, function (response) {

        if (response.ReturnStatusJSON == true) {

            $("#tbodytblServicesReport").html("");

            var counter = 1;

            $.each(response.lstDetailedServicesReturned, function (i, val) {

                $("#tbodytblServicesReport").append($('<tr>').append($('<td>').html(i))
                 .append($('<td>').html((val.EntryDateTime === null || val.EntryDateTime === "") ? "N/A" : formatJSONDate(val.EntryDateTime)))
                 .append($('<td>').html(val.InvoiceNo))
                 .append($('<td>').html(val.CustomerName))
                 .append($('<td>').html(val.VehicleRegNo))
                 .append($('<td>').html(val.ServiceName))
                 .append($('<td>').html(val.PartyName))
                 .append($('<td>').html(val.ServicePrice))
                 .append($('<td>').html(val.Commission))
                )

                i++;

                $('tfoot td#tdTotal').text(val.TotalCost);
                $('tfoot td#tdTotalCommission').text(val.TotalCommission);
                $('tfoot td#tdTotalCostMinusTotalCommission').text(val.TotalCostMinusTotalCommission);
                $('tfoot td#tdTotalExpenses').text("-"+val.TotalOtherExpenses);
                $('tfoot td#tdTotalCostMinusCommissionMinusTotalOtherExpenses').text(val.TotalCostMinusCommissionMinusTotalOtherExpenses);

                //

                counter = i;
            })

            if (counter <= 1)
            {
                $('tfoot td#tdTotal').text("");
                $('tfoot td#tdTotalCommission').text("");
                $('tfoot td#tdTotalCostMinusTotalCommission').text("");
                $('tfoot td#tdTotalExpenses').text("");
                $('tfoot td#tdTotalCostMinusCommissionMinusTotalOtherExpenses').text("");

                return;
            }

            $('#tblServicesReport').show();

            $('#tblServicesReport').DataTable({

                destroy: true,
                bPaginate: false,
                dom: 'Bfrtip',
                buttons: [
       'copyHtml5',
       'excelHtml5',
       'csvHtml5',
       {
           extend: 'pdfHtml5',
           footer: true,
           title: 'Services Report (' + $('#FromDate').val() + ' - ' + $('#ToDate').val() + ')',
           customize: function (doc) {
               doc.styles.title = {
                   color: 'gray',
                   fontSize: '15',
                   alignment: 'center'
               }

               doc.content[1].table.widths =
                   Array(doc.content[1].table.body[0].length + 1).join('*').split('');

               doc.styles.tableHeader.fontSize = 10;
               doc.styles.tableHeader.alignment = 'left';
               doc.styles.tableHeader.color = 'white'



           }
       },
       {
           extend: 'print',
           footer: true
           //title: 'Sales Report'
       }

                ]
            });


        }


        }
    });

我尝试销毁为true，funDestroy等，但似乎没有任何效果。除了使用数据表之外，我还有其他方法，它似乎每次都会产生问题。有什么解决办法吗？
