ASP.NET MVC JS发送JSON格式参数，后台获取

var queryJson = { keyword: $("#txt_keyword").val(), starttime: $("#txt_starttime").val(), endtime: $("#txt_endtime").val() } $gridList.jqGrid('setGridParam', { postData: { keyword: JSON.stringify(queryJson) } }).trigger('reloadGrid'); var expression = ExtLinq.True(); var queryParam = queryJson.ToJObject(); if (!queryParam["keyword"].IsEmpty()) { string keyword = queryParam["keyword"].ToString(); //keyWord可能为设备型号/设备名称/生产厂商/销售人员名称 string semId = salesEquipmentModelApp.SearchModelIdBySearchkey(keyword); //设备型号/设备名称/生产厂商为空 List salesRecordList = new List(); if (string.IsNullOrEmpty(semId)) { salesRecordList = salesRecordApp.SearchSalesRecordBySalesMan(keyword); } if (!string.IsNullOrEmpty(keyword)) { if (!string.IsNullOrEmpty(semId)) { expression = expression.And(t => t.SEM_ID.ToLower().Contains(semId.ToLower())); } if (salesRecordList.Count > 0) { foreach (var salesRecord in salesRecordList) { expression = expression.And(t => t.SR_ID.ToLower().Contains(salesRecord.SR_ID.ToLower())); } } } } if (!queryParam["starttime"].IsEmpty() && !queryParam["endtime"].IsEmpty()) { DateTimeFormatInfo dtFormat = new DateTimeFormatInfo(); dtFormat.ShortDatePattern = "yyyy/MM/dd"; DateTime starttime = Convert.ToDateTime(queryParam["starttime"], dtFormat); DateTime endtime = Convert.ToDateTime(queryParam["endtime"], dtFormat); expression = expression.And(t => t.SR_SALESDATE >= starttime && t.SR_SALESDATE <= endtime); } expression = expression.And(t => t.SRD_STATUS != -1);//已删除的不获取 return service.FindList(expression, pagination);
