如何在MVC3中访问JQuery DataTables插件aoData值？

我正在使用MVC 3.如何在控制器上的aoData对象中访问fnServerParams发送的数据？ 谢谢

更新：这是我试图使用的jquery …

function GenerateRows() { var serverParams = { "invoiceDate": "", "contractID": "" } serverParams.invoiceDate = $( "#InvoiceDate" ).val(); serverParams.contractID = $( "#ContractID" ).val(); $( '#invoiceRows' ).dataTable( { // Table style "bPaginate": false, "bLengthChange": false, "bSort": true, "bAutoWidth": false, "bFilter": false, "bServersSide": true, "bJQueryUI": true, "oTableTools": { "aButtons": [], "sRowSelect": "single" }, "sDom": 'Tlfrtip', // Server Parameters "fnServerParams": function ( aoData ) { aoData.push( { "name": "invoiceDate", "value": "2012-10-10" } ) }, // Aajax Call "sAjaxSource": "/Invoice/GetDailyRateBillingRows", "bProcessing": false, "bRetrieve": true, "aoColumns": [ { "sName": "Detail" }, { "sName": "Qty" }, { "sName": "Price" }, { "sName": "RowTotal" } ] } ); } 

操作方法：需要接收发票日期和合同ID

 // Method to return InvoiceRows for DailyRate billing public ActionResult GetDailyRateBillingRows(jQueryDataTableParamModel param) { // Hard coded. Need to receive parameters from Ajax post. (DataTables request.) DateTime invoiceDate = new DateTime(2012, 12, 31); int contractID = 1; int contractDayRate = db.Contracts.Where(c => c.Id == contractID).First().UnitRate; List invoiceRows = new List(); List businessDaysOfMonth = new List(); var firstDayOfMonth = new DateTime(invoiceDate.Year, invoiceDate.Month, 1); var lastDayOfMonth = firstDayOfMonth.AddMonths(1).AddDays(-1); var holidays = db.Holidays.Where(h => h.DateOfHoliday >= firstDayOfMonth && h.DateOfHoliday <= lastDayOfMonth); // Get all the week days into businessDaysOfMonth for (DateTime date = firstDayOfMonth; date <= lastDayOfMonth; date = date.AddDays(1)) { if (date.DayOfWeek != DayOfWeek.Saturday && date.DayOfWeek != DayOfWeek.Sunday) businessDaysOfMonth.Add(date); } // Now remove the matching public holidays. foreach (var item in holidays) { businessDaysOfMonth.Remove(item.DateOfHoliday); } // .. and create list of invoiceRow items. foreach (var item in businessDaysOfMonth) { invoiceRows.Add(new InvoiceRow { InvoiceID = 0, ItemPrice = contractDayRate, RowDetail = GetDateString(item), RowQty = 1, RowTotal = contractDayRate }); } var result = from c in invoiceRows select new[] { c.RowDetail, c.RowQty.ToString(), c.ItemPrice.ToString(), c.RowTotal.ToString() }; return Json(new { eEcho = param.sEcho, iTotalRecords = invoiceRows.Count(), iTotalDisplayRecords = invoiceRows.Count(), aaData = result }, JsonRequestBehavior.AllowGet); } private string GetDateString(DateTime date) { return date.ToString("dddd dd MMM yyyy"); } protected override void Dispose(bool disposing) { db.Dispose(); base.Dispose(disposing); } } 

Answer 1

首先，请注意fnServerParams是1.8.2版本以来的新版本，因此请确保您运行的是最新版本的dataTables。

你应该能够在你的Controller方法（ GetDailyRateBillingRows ）中得到它：

 var invoiceDate = HttpContext.Request["invoiceDate"];
