            using (var multi = con.QueryMultiple("usp_FGMOQMapping_GetList_AutoSuggest", parameters, commandType: CommandType.StoredProcedure)) {
                fGMOQMapping.FGList=multi.Read<FGMOQMapping>().ToList();
                fGMOQMapping.SFGList = multi.Read<FGMOQMapping>().ToList();
            }
                return fGMOQMapping;
        }

controller

 public JsonResult NPDAutoSuggest()
        {
            NPD npdObject = new NPD();
            //npdObject.FGList = _purchaseOrderRepository.GetFGMOQMappingList(0, Convert.ToInt64(Session["UserId"]));
            FGMOQMapping fGMOQMapping = new FGMOQMapping();
            fGMOQMapping= _purchaseOrderRepository.GetFGMOQMappingAutoSuggest(Convert.ToInt64(Session["UserId"]));
            npdObject.FGList = fGMOQMapping.FGList;
            npdObject.SFGList = fGMOQMapping.SFGList;
            npdObject.PlantList = _plantRepository.GetPlantList(0, "", "", Convert.ToInt64(Session["UserId"]));
            var Jsondata = JsonConvert.SerializeObject(npdObject);
            return Json(Jsondata, JsonRequestBehavior.AllowGet);
        }

ajax , js

$.ajax({
        
        url: ROOT   "PurchaseOrder/NPDAutoSuggest",
        type: 'POST',
        datatype:'JSON',
        success: function (result) {
            
            AutoData = JSON.parse(result);
        },
        error: function (result) {
            console.log(result);
            alert("not");
        }
    });

ajax is hitting error block, please help me out to solve this

CodePudding user response：

You create an anonymous object to send to the ajax success method. like this

return Json(new { data = Jsondata }, JsonRequestBehavior.AllowGet);

And in ajax get this anonymous object

success: function (result) {
    AutoData = JSON.parse(result.data); //Get data object
}

CodePudding user response：

hello everything was fine here . but json limit exceeded so i used return in different way in controller (if You have large amount of data we may get this issue so use this return kind)

public JsonResult NPDAutoSuggest()
        {
            NPD npdObject = new NPD();
            FGMOQMapping fGMOQMapping = new FGMOQMapping();
            fGMOQMapping = _purchaseOrderRepository.GetFGMOQMappingAutoSuggest(Convert.ToInt64(Session["UserId"]));
            npdObject.FGList = fGMOQMapping.FGList;
            npdObject.SFGList = fGMOQMapping.SFGList;
            npdObject.PlantList = _plantRepository.GetPlantList(0, "", "", Convert.ToInt64(Session["UserId"]));
            return new JsonResult
            {
                Data = npdObject,
                MaxJsonLength = Int32.MaxValue
            };
        }
