Question

我有一个包含大量行的webgrid，每行都有一个复选框。如果我选择10行，我可以将数据推送到我在控制器中的方法并更新数据库。一旦选择的行超过20，则没有任何反应。我不能走进我的方法。我可以通过json传递限制吗？你觉得怎么回事？

这是我的jquery代码

           $('#MultipleAcctAssignSubmit').click(function () {

                    var routeselected = $('#ddlroutes :selected').val();
                    var repsselected = $('#ddlreps :selected').val();

                    var routeselectedText = $('#ddlroutes :selected').text();
                    var repsselectedText = $('#ddlreps :selected').text();            

                    var branchcode = $("#ddlDropDownList option:selected").text();
                    var values = [];
                    $("#container-grid input[name=CatalogOrderId]:checked").each(function () {
                        row = $(this).closest("tr");

                        if (routeselected == "") {
                            //routeselected = $(row).find("td div.RouteId").text();
                            //routeselected = $(".routeId").val();
                            routeselected = 0;                   
                        }

                        if (repsselected == "") {
                            //repsselected = $(row).find("td div.primrep").text();
                            //repsselected = $(".PrimaryRepId").val();
                            repsselected = 0;
                        }

                        values.push({
                            CatalogOrderId: $(row).find("input[name=CatalogOrderId]").val(),
                            RouteId: routeselected,
                            Primaryrep: repsselected,
                            Isvalidated: "Assigned"
                        });
                    });
                    console.log(values);

                    if (values.length < 1) {
                        ShowDialogBox('Selection of rows', 'No records have been selected. Please select the record(s) you wish to assign.', 'Ok', '', 'GoToAssetList', null);
                        return;
                    }

                    /* Do some stuff with the values collected */            
                    var things = JSON.stringify({ 'CatalogSelectedOrders': values });

                    $.get('@Url.Action("SubmitCatalogOrders", "Home")', { 'values': things, 'strBranchcode': branchcode }, function(result) {
                        $('#scrolltable').html(result);
                    });

                });

这是我在控制器中的方法

                public ActionResult SubmitCatalogOrders(string values, string strBranchcode)
                {
                    Grabpartialviewdata objcatsubmit = new Grabpartialviewdata();
                    string stripOutBranchName = string.Empty;
                    stripOutBranchName = strBranchcode.Substring(0, 3);
                    string status = string.Empty;
                    List<Catalogorder> cleanedData = null;

                    try
                    {
                        var stripOffObjectName = JObject.Parse(values)["CatalogSelectedOrders"];
                        cleanedData = JsonConvert.DeserializeObject<List<Catalogorder>>(stripOffObjectName.ToString());
                        status = _edmDataService.ProcessWriteAssingedRowsToDb(cleanedData, stripOutBranchName);
                        ViewData["SelectList"] = HttpContext.Session["SelectList"] ?? new List<Int64>();

                        if (status == "success")
                        {
                            objcatsubmit = _edmDataService.GetPartialViewData(stripOutBranchName);
                        }

                    }
                    catch (Exception ex)
                    {
                        logger.Error(ex);
                    }

                    return PartialView("_Edmcatorderdetails", objcatsubmit);

                }

您的代码正在使用SQL2014方法进行GET调用。 GET调用通过查询字符串发送数据并具有限制。

您应该考虑使用在请求正文中发送数据的POST调用。您可以使用jquery $.get方法。

$.post

此外，我发现您将所有内容作为单个字符串值发送。你不需要这样做。您可以发送javascript对象并使用视图模型作为参数，默认模型绑定器将能够将发布的对象映射到视图模型对象属性。

无法使用json将大量数据推送到控制器
