c# - 为什么 jquery datable 显示旧记录而不是新记录？

Question

我在页面加载时由视图模型填充数据表。没关系。

现在我想在单击下拉列表时用一条记录填充它。但是数据表显示的是旧记录而不是新记录。

我试过这个：

        table = $("#tblCertificates").DataTable();

        $.get("/CertificatesNew/FillCertificates", data);

        table.clear();

但不工作。我想在重新填充新数据之前使 jquery 数据表为空。

 [HttpGet]
        [OutputCache(NoStore = true, Duration = 0)]
        public ActionResult FillCertificates(int ID)
        {
            InspectionReportsViewModel InspectionReportsViewModel = new InspectionReportsViewModel();

            try
            {

                InspectionReportDAL InspectionReportDAL = new DAL.InspectionReportDAL();
                InspectionReportsViewModel.InspectionReportList = InspectionReportDAL.GetInspectionReportListFilteredByClientID(ID);

                ClientsDAL clientsDAL = new ClientsDAL();

                ViewBag.ClientsList = clientsDAL.GetClientsList();

                return View("Index", InspectionReportsViewModel); 
            }
            catch
            {
                return View();
            }

        }

api调用：

<script type="text/javascript">
        $('#tblCertificates').DataTable({
            responsive: true,
            searching: true,
            ordering: false,

        });

        $("#SearchInspectionReport_Client_ID").change(function () {
            var ID = $("#SearchInspectionReport_Client_ID").val(); //Client ID



            //if(!Number(ID)) // to check if '-Select-' has been selected, so in that case it should be stopped from further execution
            //{
            //    $("#InspectionReport_PoNo").val('');
            //}

            data = { 'ID': ID } //Client ID

            table = $("#tblCertificates").DataTable();
            //oSettings = table.fnSettings();



            $.get("/CertificatesNew/FillCertificates", data);

            table.clear();
        });

    </script>
}

桌子：
