Via the 'data' properie on a ajax post i want to send a parameter to the action method. All values in the parameter object get through except the decimal/double values. Why is this and what can i do about it?
I have tried to change the value to string and even int. And it gets through but it is important that it gets through as a decimal or double.
mapHub.client.requestForHelpInClient = function (requestDetails) {
$.ajax({
type: "POST",
url: '#Url.Action("RequestPartialView", "Supplier")',
data: requestDetails,
success: function (response) {
$("#Request").html(response);
},
error: function (error) {
console.log(error);
}
});
}
[HttpPost]
public ActionResult RequestPartialView(RequestDetails reqDetails)
{
RequestViewModel reqVm = new RequestViewModel() { requestDetails = reqDetails };
return PartialView("RequestPartialView",reqVm);
}
//This is the object i pass into requestForHelpInClient function that executes the ajax call
public class RequestDetails
{
public int CustomerId { get; set; }
public Customer Customer { get; set; }
public int NumberOfHours { get; set; }
public string TypeOfMachine { get; set; }
public List<Supplier> NearestSupplierList { get; set; }
}
public class Customer : MapClient
{
public int CustomerID { get; set; }
public string AspNetUserID { get; set; }
public string Name { get; set; }
public double Latitude { get; set; }
public double Longitude { get; set; }
}
every value gets through from the ajax call to the action method parameter excepts the latitude and longitude decimal values.
I get no error message. The value just says '0'
You need to stringify your object before posting
mapHub.client.requestForHelpInClient = function (requestDetails) {
$.ajax({
type: "POST",
url: '#Url.Action("RequestPartialView", "Supplier")',
data: JSON.stringify(requestDetails),
success: function (response) {
$("#Request").html(response);
},
error: function (error) {
console.log(error);
}
});
}
That should fix it

I am using jquery ajax to make a call to C# controller's method and here is the controllers method:
public ActionResult AddRegion(string pageIdIn, string fieldIdIn, RegionMV regionMv)
{
var fieldRegFormDataOutMv = batchLogic.AddRegion(Session.SessionID, pageIdIn, fieldIdIn, regionMv);
var json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(fieldRegFormDataOutMv);
return Json(json, JsonRequestBehavior.AllowGet);
}
Here is the ajax call code:
function AjaxWrapper(param, url, success, failure, deferred, args) {
return $.ajax({
type: "POST",
url: url,
data: param,
// contentType: "application/json; charset=utf-8",
//dataType: "json",
success: function (data, textStatus, jqXHR) {
success(data, args);
deferred.resolve();
},
error: function (jqXHR, textStatus, errorThrown) {
// //! call the function that will pop a div in the view to tell the user something went wrong - > failure(response);
failure(textStatus);
console.log(jqXHR);
deferred.reject();
},
cache: false
});
}
And here is the code that calls the ajax method:
function addRegion(pageId, fieldId, region) {
var param = { pageIdIn: pageId, fieldIdIn: fieldId, regionMv: region };
var deferred = $.Deferred();
showProgress();
AjaxWrapper(param, window.urlsList.addRegionUrl, updateView, showError, deferred).done(function () {
hideProgress();
});
return deferred.promise();
}
The problem is that on my computer(using Windows 7) the region json is being mapped to a RegionMV object correctly(with all properties and a correct bounding box), but on another computer(using Windows 10) the region's properties are mapped correctly except the bounding box.
Here is the class RegionMV:
public class RegionMV
{
// Index of the region in the parent page
public string Id { get; set; }
// Region type
public RegionType Type { get; set; }
// Region bounding box
public RectMV BoundingRect { get; set; }
// Region confidence as a specific field (determined by the 'Name' property)
public int FieldConfidence { get; set; }
// Region name (filled for regions assigned to specific fields or cells)
public string Name { get; set; }
// Region text content
public string Content { get; set; }
// Region text content filtered as specific field (determined by the 'Name' property) value
public string ContentFiltered { get; set; }
}
Any ideas why is that happening? Is it because of the different operational systems(I kind of doubt that, but still?) or because of something else?
EDIT!
Here is my RectMV class:
public class RectMV
{
public double X { get; set; }
public double Y { get; set; }
public double Width { get; set; }
public double Height { get; set; }
}
And the Chrome Versions are the same on both machines.
My ViewModel is:
public class CFUViewModel
{
public int RID { get; set; }
public int Order { get; set; }
public List<VCItem> VItems{ get; set; }
}
where VCItem is:
public class VCItem
{
public string Name{ get; set; }
public string Category { get; set; }
}
In my view, I am collecting the data from form elements. Thus,
$('#submit').click(function () {
console.log(gatherData());
transmitData(gatherData());
});
function gatherData() {
var vc = dataObject.getVCItems();
//This is a knockout function that gives an array of VCItems
var data = new Object();
data.RID = $('#rid').val();
data.VItems = vc;
return data;
};
function transmitData(dataToSend) {
$.ajax({
url: '../CFUDashboard/ReceiveData',
type: 'post',
dataType : 'json',
success: function (data) {
alert('success');
},
data: dataToSend
});
};
In the controller, I have:
[HttpPost]
public ActionResult ReceiveData(CFUViewModel viewModel)
{
//...
}
The problem is, though RID is ok, VItems list is not serialized. I suspect, the reason is, the array attached to the JS object is actually string (array wrapped in quotes). This is confirmed by the console.log(gatherData())
It is outputted as:
VItems : "[{"Name":"OPV3","Category":"FUGY"},{"Name":"OPV7","Category":"FUGX"}]"
What is the reason for not getting the list serialized? What am I missing?
I wrote this Controller:
[HttpPost]
public JsonResult CheckOut(List<POS_model> pos, double totalPayment)
{
try
{
var json = JsonConvert.SerializeObject(pos);
DataTable posTable = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));
posTable.Columns["discount_percent"].ColumnName = #"Discount %";
POS m_pos = new POS();
m_pos.Data = posTable;
m_pos.totalPayment = totalPayment;
m_pos.CheckOut();
return Json(new
{
Status = "Success"
});
}
catch
{
return Json(new
{
Status = "Fail"
});
}
}
And i attempted wrote this AJAX script to call and submit the parameters to the Controller:(but it didn't work)
var totalPay = 1000;
var GatherPosItems = $('#tblPOS').tableToJSON();
$.ajax({
type: 'POST',
data: JSON.stringify(GatherPosItems)+"&totalPayment="+totalPay,
url: '#Url.Action("CheckOut", "POS")',
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert('Success');
},
error: function (req, status, errorObj) {
alert(errorObj.toString());
}
});
The GatherPosItems is a JSON with multiple "Rows" or Objects, so it's an array.
I added a parameter totalPayment.
How can i pass Both GatherPosItems and totalPayment to the Controller?
my Model:
public class POS_model
{
public string Qty { get; set; }
public string description { get; set; }
public string price { get; set; }
public string discount_percent { get; set; }
public string Discount_amount { get; set; }
public string Discounted_price { get; set; }
public string Line_total { get; set; }
public string is_vat { get; set; }
public string track_type { get; set; }
public string item_line_id { get; set; }
public string id { get; set; }
public string sale_code { get; set; }
public string reference { get; set; }
public string unit_of_measure { get; set; }
public string location { get; set; }
public string item_code { get; set; }
}
My GatherPosItems's RESULT:
You concatenate a non-JSON string (&totalPayment="+totalPay) to the JSON returned from JSON.stringify function, which corrupts the format of data being sent to the server and makes the model binder unable to parse it.
The following should work:
$.ajax({
type: 'POST',
data: JSON.stringify({pos: GatherPosItems, totalPayment: totalPay}),
url: '#Url.Action("CheckOut", "POS")',
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function(data) {
alert('Success');
},
error: function(req, status, errorObj) {
alert(errorObj.toString());
}
});
I know I've done this before but I can't seem to get this to work.
I have the following JavaScript;
$("#btnTestVouchers").click(function () {
var postData = {
"workplaceGiverId": $(".wpgDropdownList").val(),
"fromMemberId": $(".wpgFromMemberDropdownList").val(),
"toMemberId": $(".wpgToMemberDropdownList").val(),
"voucherExpiryDate": $("#expiryDatePicker").val(),
"recipients": JSON.stringify("[{'firstname':'a','lastname':'b','email':'c','voucheramount':'d'}]")
};
console.log(postData);
$.ajax({
type: "POST",
url: "/Admin/TestVoucherCreationEmails",
contentType: 'application/json; charset=utf-8',
dataType: "json",
data: JSON.stringify(postData),
success: function (d) {
alert("OK");
},
error: function (xhr, textStatus, errorThrown) {
alert("Error:" + errorThrown);
}
});
});
In my model I have;
public class postDataObject
{
public int workplaceGiverId { get; set; }
public int fromMemberId { get; set; }
public int toMemberId { get; set; }
public string voucherExpiryDate { get; set; }
public IEnumerable<BulkVoucherRecipient> recipients { get; set; }
}
public class BulkVoucherRecipient
{
public string firstname { get; set; }
public string lastname { get; set; }
public string email { get; set; }
public string voucheramount { get; set; }
}
In my controller I have;
[HttpPost]
public void TestVoucherCreationEmails(postDataObject postedData)
{
string g = "";
}
However when I post, the list of recipients is always empty.
If I don't Stringify the list of recipients I get the same result.
Anyone know what I'm doing wrong?
edit
The other values all come through ok, just the List is empty.
You don't need to JSON.stringify the recipients.
"recipients": JSON.stringify("[{'firstname':'a','lastname':'b','email':'c','voucheramount':'d'}]")
Remove JSON.stringify form here and it should work.
var postData = {
"workplaceGiverId": $(".wpgDropdownList").val(),
"fromMemberId": $(".wpgFromMemberDropdownList").val(),
"toMemberId": $(".wpgToMemberDropdownList").val(),
"voucherExpiryDate": $("#expiryDatePicker").val(),
"recipients": [{'firstname':'a','lastname':'b','email':'c','voucheramount':'d'}]
};
Try this, It should work
[HttpPost]
public void TestVoucherCreationEmails([FromBody]postDataObject postedData)
{
string g = "";
}
Background:
In the view, we ask (via jquery and ajax) the controller for data from the database. The data is returned as Json, but for reasons unknown one part of the Json object is returned as null, even though it is properly set in the controller's JsonResult.
The Code:
The class to be returned as JsonResult
public class InData
{
public InData() { }
public AppsWithActions[] apps { get; set; }
public User[] users { get; set; }
public string timePeriod { get; set; }
public string startDate { get; set; }
public string endDate { get; set; }
public string dataType { get; set; }
}
The Problem is the string arrays actionIds and actionNames in the following class are null in the javascript, even though they have the correct values in the JsonResult:
public class AppsWithActions
{
public AppsWithActions() { }
public string id { get; set; }
public string name { get; set; }
public string[] actionIds { get; set; }
public string[] actionNames { get; set; }
}
The controller function that sets the InData and returns it to the javascript:
//Takes a goal setting, turns it to indata and returns a JsonResult
public JsonResult GetIndataFromGoalSettingId(SettingId settingId)
{
var id = ToGuid(settingId.idString);
GoalSetting setting = Session.Query<GoalSetting>()
.Where(x => x.Id == id)
.FirstOrDefault();
var indata = TransformGoalSettingToInData(setting);
return Json(new { returnvalue = indata }, JsonRequestBehavior.AllowGet);
}
The ajax call that returns everything correct, except the apps.actionIds and apps.actionNames
function getIndataFromGoalSettingId(settingId) {
if (settingId != null) {
settingIdIn = { "idString": settingId};
$.ajax({
type: "POST",
async: false,
traditional: true,
url: 'GetIndataFromGoalSettingId',
data: JSON.stringify(settingIdIn),
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (result) {
//...
}
});
}
}
It should be said that we have successfully used the same kind of infrastructure for getting data and returning it as Json to the javascript before, but if anyone has a better suggestion feel free to spell it out!
