Passing A Single Objects Into An MVC Controller Method Using jQuery Ajax

I'm trying to post a single object data to an MVC Controler using JQuery, Below are my codes.
//declare of type Object of GroupData
var GroupData = {};
//pass each data into the object
GroupData.groupName = $('#groupName').val();
GroupData.narration = $('#narration').val();
GroupData.investmentCode = $('#investmentCode').val();
GroupData.isNew = isNewItem;
//send to server
$.ajax({
url: "/Admin/SaveContributionInvestGroup",
type: "POST",
contentType: "application/json;charset=utf-8",
dataType: "json",
data: JSON.stringify({ GroupData: JSON.stringify(GroupData) }),
success: function (res) {
alertSuccess("Success", res.Message);
//hide modal
$('#product-options').modal('hide');
hide_waiting();
},
error: function (res) {
alertError("Error", res.Message);
}
});
Below is my controller.
[HttpPost]
public JsonResult SaveContributionInvestGroup(ContributionInvestmentGroup GroupData)
{
ClsResponse response = new ClsResponse();
ClsContributionInvestmentGroup clsClsContributionInvestmentGroup = new ClsContributionInvestmentGroup();
var userID = (int)Session["userID"];
var sessionID = (Session["sessionID"]).ToString();
if (contributionGroupData != null)
{
//get the data from the cient that was passed
ContributionInvestmentGroup objData = new ContributionInvestmentGroup()
{
contributionInvestmentGroupID = 0,
groupName = GroupData.groupName,
narration = GroupData.narration,
investmentCode = GroupData.investmentCode,
isNew = GroupData.isNew
};
response = clsClsContributionInvestmentGroup.initiateNewContributionInvestmentGroup(sessionID, objData);
}
else
{
response.IsException = true;
response.IsSucess = false;
response.Message = "A system exception occurred kindly contact your Administrator.";
}
return Json(new
{
response.IsSucess,
response.Message
});
}
The issue is, the data is not been posted to the controller, the controller receives a null object.
Kindly assist, would really appreciate your effort, thanks.

Try Like this:
//send to server
$.ajax({
type: "POST",
url: "/Admin/SaveContributionInvestGroup",
dataType: "json",
data: GroupData,
success: function (res) {
alertSuccess("Success", res.Message);
//hide modal
$('#product-options').modal('hide');
hide_waiting();
},
error: function (res) {
alertError("Error", res.Message);
}
});

in your controller your dont have custom binding to bind JSON to your model thats why you get null in you parameter.
instead just post it as query, try simply changes your ajax option like so:
{
...
contentType: "application/x-www-form-urlencoded", //default:
...,
data: $.param(GroupData),
...
}
and perhaps property names are case sensitive so you will need to change your javascript model's name

JSON Object always return undefined with AJAX

The JSON Object always return undefined in spite of the object contains data, i check it by using breakpoints in debugging
This is Action method in Controller:
public JsonResult GetMoreComments(int CommsCount, int ArticleID)
{
List<ComViewModel> comms = articleService.GetMoreComments(ArticleID, CommsCount);
return Json( comms );
}
and I also replaced the code in Action method to simple code like that but not work too:
public JsonResult GetMoreComments(int CommsCount, int ArticleID)
{
ComViewModel com = new ComViewModel
{
CommentContent = "cooooooooooontent",
CommentID = 99,
SpamCount = 22
};
return Json( com );
}
This is jQuery code for AJAX:
function GetMoreComments() {
$.ajax({
type: 'GET',
data: { CommsCount: #Model.Comments.Count, ArticleID: #Model.ArticleID },
url: '#Url.Action("GetMoreComments", "Comment")',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
var JsonParseData = JSON.parse(result);
alert(JsonParseData[0].CommentID)
alert(result[0].CommentID);
alert(result[0]["CommentID"]);
}
});
}

Usually you would have to parse your data if you need to alert it the way you have it. alert(result) should show data. If you need to access array of objects you must parse it first. Here is my example....
jQuery.post(ajaxurl, data, function(response) {
alert('Got this from the server: ' + response);
//PARSE data if you need to access objects
var resultstring = response.replace(',]',']');
var JsonParseData = JSON.parse(resultstring);
alert(JsonParseData[0].address)
});
That is wordpress ajax but its the same concept

JQuery TypeError: Converting circular structure to JSON in MVC

Facing error on JSON.stringify(ApplObj) :
How to post this object to controller
JQuery Code -
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplObj = {
ApplicantName: ApplName, ApplicantMobile: ApplMobile, ApplicantEmailId: ApplEmail, ApplFHName: ApplicantFHName
}
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplObj),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data);
}
});
Controller Code...
this jsonresult used for save records and return value...
this code is working in other project....
public JsonResult SaveApplicatDetail()
{
try
{
var resolveRequest = HttpContext.Request;
TicketMasterModel TMM = new TicketMasterModel();
resolveRequest.InputStream.Seek(0, SeekOrigin.Begin);
string jsonString = new StreamReader(resolveRequest.InputStream).ReadToEnd();
if (jsonString != null)
{
TMM = (TicketMasterModel)js.Deserialize(jsonString, typeof(TicketMasterModel));
}
int TicketId = 0;
using (var db = new UnitOfWork())
{
DAL.tbl_TrnTicketMaster TM = new DAL.tbl_TrnTicketMaster();
TM.ApplicantName = TMM.ApplicantName;
TM.ApplicantMobile = TMM.ApplicantMobile;
TM.ApplicantEmailId = TMM.ApplicantEmailId;
TM.ApplicantFHName = TMM.ApplicantFHName;
TM.FK_CompanyId = 1;
TM.CustomerId = UserSession.UserId;
TM.IsSubmissionLocked = false;
TM.CreatedBy = UserSession.UserId;
db.tbl_TrnTicketMaster.Insert(TM);
TicketId = TM.PK_TicketId;
}
return Json(TicketId, JsonRequestBehavior.AllowGet);
}
catch (Exception)
{
throw;
}
}

basically JSON.stringify turns a Javascript object into JSON text and stores that JSON text in a string.
try this,
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplObj = {
'ApplicantName': ApplName, 'ApplicantMobile': ApplMobile, 'ApplicantEmailId': ApplEmail, 'ApplFHName': ApplicantFHName
}
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplObj),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data);
}
});

Problem Resolved -
"JSON.stringify" is used array to convert it.
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplDetails = {
ApplicantName: ApplName,
ApplicantMobile: ApplMobile,
ApplicantEmailId: ApplEmail,
ApplicantFHName: ApplFHName
}
var ApplObj = { ApplicantDetail: ApplDetails };
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplDetails),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
}
});

How to use q.js to chain backbone model?

I have the following:
var q = new app.models.OverwriteLineItemsProcess();
q.set('id', $("#process_id").val());
q.saveSource($("#source_quote").val());
q.lockSource();
saveSource is sending data to the backend using ajax. So is lockSource.
I want to execute in this SEQUENTIAL manner: saveSource >> lockSource.
How do I write the q.js to make it work?
By q.js, I mean https://github.com/kriskowal/q
UPDATE: added saveSource and lockSource
saveSource: function (quotation_id) {;
var type = "PUT";
var verb = "Updated";
var headers = {
'X-HTTP-Method-Override': type
};
var url = app.base_url + "/overwrite_line_items/" + this.id;
this.set('source_quote', quotation_id);
var data = this.toFormData();
var result = false;
var currentModel = this;
var settings = {
headers: headers,
type: type,
url: url,
data: data,
success: function(json) {
response = JSON && JSON.parse(json) || $.parseJSON(json);
console.log(response);
currentModel.lockSource();
$("#facebox-source-quote-status").html('<font color="green">SELECTED</font>');
},
error: function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
},
dataType: 'json'
};
$.ajax(settings).done(function() {
});
},
lockSource: function () {
var type = "PUT";
var verb = "Updated";
var headers = {
'X-HTTP-Method-Override': type
};
var url = app.base_url + "/quotations/is_editable/" + this.attributes.source_quote;
var data = this.toFormData();
var result = false;
var currentModel = this;
var settings = {
headers: headers,
type: type,
url: url,
data: data,
success: function(response) {
console.log(response);
},
error: function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
},
dataType: 'json'
};
$.ajax(settings).done(function() {
});
},

The jQuery.ajax function which you're using already returns a promise for its result. You just need to return that from your functions:
saveSource: function (quotation_id) {;
…
var settings = {
headers: headers,
type: type,
dataType: 'json', // jQuery will automatically parse it for you
url: url,
data: data
};
return $.ajax(settings).done(function() {
// ^^^^^^
$("#facebox-source-quote-status").html('<font color="green">SELECTED</font>');
// notice I did remove the currentModel.lockSource(); call from the callback
}, function() {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
});
},
lockSource: function () {
…
var settings = // analoguous, no callbacks here
return $.ajax(settings).fail(function(response) {
$("#facebox-source-quote-status").html('<font color="red">UNABLE TO SELECT</font>');
});
}
Now you can easily chain them:
var q = new app.models.OverwriteLineItemsProcess();
q.set('id', $("#process_id").val());
q.saveSource($("#source_quote").val()).then(function(saveResponse) {
console.log(saveResponse);
return q.lockSource();
}).done(function(lockResponse) {
console.log(lockResponse);
});
You don't even need Q for that. If you want to use it, wrap the $.ajax() calls in a Q() invocation, as explained in the Converting JQuery Promises to Q section of the docs.
