Why it value does not send in to ajax post?

I'm a newbie working with ajax. I have a problem while sending the data into ajax post.
The output of console.log(obj.Id) and console.log(oke) is 2. Then I tried to send it through data in ajax, but it end up 0 in the controller.
$(function () {
$("body").on('click', '#btnEdit', function () {
alert("clicked ok");
$("#addRowModal").modal("hide");
var obj = {};
obj.Id = $(this).attr('data-id');
oke = $(this).data("id");
console.log(obj.Id)
console.log(oke)
$.ajax({
url: '#Url.Action("Details", "InvoicePPh")',
data: oke,
type: 'POST',
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (response) {
alert("sukses");
},
error: function(response) {
alert("error")
}
});
});
});
And my controller looks like this
[HttpPost]
public JsonResult Details(int id)
{
var obj = dbContext.invoicePPhs.FirstOrDefault(s => s.Id == id);
InvoicePPh pph = new InvoicePPh();
pph2326.TaxForm = obj.TaxForm;
return Json(pph);
}
I want the '2' value that passes into my controller, how can I do that? Thank you for your help.

An alternative way to send your data your Controller method using Ajax would be to wrap your data in a JSON object and then send it to the server for processing. The server will be then deserialize your JSON object and you can access the required properties from that process:
$(function () {
$("body").on('click', '#btnEdit', function () {
alert("clicked ok");
$("#addRowModal").modal("hide");
var obj = {};
obj.Id = $(this).attr('data-id');
oke = $(this).data("id");
console.log(obj.Id)
console.log(oke)
var json = {
oke: oke
};
$.ajax({
url: '#Url.Action("Details", "InvoicePPh")',
data: {'json': JSON.stringify(json)},
type: 'POST',
dataType: "json",
success: function (response) {
alert("sukses");
},
error: function(response) {
alert("error")
}
});
});
});
And your Controller method will be:
using System.Web.Script.Serialization;
[HttpPost]
public JsonResult Details(string json)
{
var serializer = new JavaScriptSerializer();
dynamic jsondata = serializer.Deserialize(json, typeof(object));
//Get your variables here from AJAX call
var id= Convert.Int32(jsondata["id"]);
var obj = dbContext.invoicePPhs.FirstOrDefault(s => s.Id == id);
InvoicePPh pph = new InvoicePPh();
pph2326.TaxForm = obj.TaxForm;
return Json(pph);
}

If you just need id in your method parameter just change data in ajax to:
contentType: "application/x-www-form-urlencoded",
data: { 'id': oke },
id is name of parameter from controller method.

Please change the data property in ajax part.
$.ajax({
url: '#Url.Action("Details", "InvoicePPh")',
data: { 'id': oke },
type: 'POST',
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (response) {
alert("sukses");
},
error: function(response) {
alert("error")
}
});

Display error on ajax response from php function

I have some ajax call like this
function ExportData() {
var data = {
action: "export_database", // the name of your PHP function!
};
jQuery.ajax({
type: "POST",
url: ajaxurl,
data: data,
beforeSend: function () {},
success: function (data) {
alert(data);
},
});
}
And php function like this
function export_database(){
return $response;
}
The problem is in that response I have something like this
{
"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
"title": "One or more validation errors occurred.",
"status": 400,
"traceId": "|3fa58ee1-48bf0cb9f60bfa25."
}
I want to alert only title, but when i try data.title , i got undefine
Do I must encode or decode something, thanks?

This is what you need. Just access the object by data.title and it will show in the alert()
You need to define dataType as json in your request.
If its does not work then use JSON.parse(data) like this:
var response = JSON.parse(data)
alert(response.title)
Try below:
function ExportData() {
var data = {
action: "export_database", // the name of your PHP function!
};
jQuery.ajax({
type: "POST",
url: ajaxurl,
dataType: 'json'
data: data,
beforeSend: function () {},
success: function (data) {
alert(data.title);
},
error: function(error){
//Error
alert(error.title)
}
});
}
Hope this helps.

Try Below:
function ExportData() {
var data = {
action: "export_database", // the name of your PHP function!
};
jQuery.ajax({
type: "POST",
url: ajaxurl,
data: data,
beforeSend: function () {},
success: function (data) {
var parsedData = jQuery.parseJSON(data)
alert(parsedData.title);
},
});
}

You have to use JSON.parse() for accessing data objects Like this:
function ExportData() {
var data = {
action: "export_database", // the name of your PHP function!
};
jQuery.ajax({
type: "POST",
url: ajaxurl,
data: data,
beforeSend: function () {},
success: function (data) {
var res = JSON.parse(data)
alert(res.title);
},
});
}

Web service receiving null with jQuery post JSON

The web service on http://localhost:57501/api/addDatabase has the following code.
[System.Web.Mvc.HttpPost]
public ActionResult Post(addDatabase pNuevaConeccion)
{
pNuevaConeccion.insertarMetaData();
return null;
}
The Ajax function is on a javascript that creates the JSON from the give values on http://localhost:1161/CreateServer.
$(document).ready(function ()
{
$("#createServer").click(function (e) {
e.preventDefault(); //Prevent the normal submission action
var frm = $("#CreateServerID");
var dataa = JSON.stringify(frm.serializeJSON());
console.log(dataa);
$.ajax({
type: 'POST',
url: 'http://localhost:57501/api/addDatabase/',
contentType: 'application/json; charset=utf-8',
crossDomain: true,
//ContentLength: dataa.length,
data: dataa,
datatype: 'json',
error: function (response)
{
alert(response.responseText);
},
success: function (response)
{
alert(response);
if (response == "Database successfully connected") {
var pagina = "/CreateServer"
location.href = pagina
}
}
});
});
});
When I run this code an alert pops up saying "undefined" but if I delete the contentType the alert doesn't show up. The problem is that the variables that the function Post (from the web service) receives are NULL even though I know that the JSON named dataa is not NULL since I did a console.log.
I have seen various examples and pretty much all of them say that I should use a relative URL but the problem is that since there are 2 different domains and when I tried it, it couldn't find the URL since it's not in the same localhost.

Web service should return a JSON format instead of null. like below example.
public JsonResult Post()
{
string output = pNuevaConeccion.insertarMetaData();
return Json(output, JsonRequestBehavior.AllowGet);
}

try to use this code for calling the web method
$.ajax({
method: "POST",
contentType: "application/json; charset=utf-8",
data: dataa,
url: 'http://localhost:57501/api/addDatabase/',
success: function (data) {
console.log(data);
},
error: function (error) {
console.log(error);
}
});

its my old code.(ensure action parameter variable name and post variable name are same)
$('#ConnectionAddres_ZonesId').change(function () {
var optionSelected = $(this).find("option:selected");
var id = { id: optionSelected.val() };
$.ajax({
type: "POST",
url: '#Url.Action("GetParetArea", "Customers")',
contentType: "application/json;charset=utf-8",
data: JSON.stringify(id),
dataType: "json",
success: function (data) {
$('#ConnectionAddres_ParentAreaId').empty().append('<option value="">Select parent area</option>');
$.each(data, function (index, value) {
$('#ConnectionAddres_ParentAreaId').append($('<option />', {
value: value.Id,
text: value.Area
}));
});
},
});
});
public ActionResult GetParetArea(int id)
{
var parents="";
return Json(parents, JsonRequestBehavior.AllowGet);
}

How to pass a list of id's in a AJAX request to the Server in MVC

In a AJAX request to the server in MVC, how can I pass a list of id's to the controller's action function?
I accept with or without use of Html helpers.
I know MVC's model binder has no problem when it comes to simple types like int, string and bool.
Is it something like I have to use and array instead in the action?
I don't care if I have to use an array or List and even if the strings I int or strings I can always convert them. I just need them on the server.
My List ids gives null at the moment.
Javascript:
var ids= [1,4,5];
// ajax request with ids..
MVC Action:
public ActionResult ShowComputerPackageBuffer(List<int> ids) // ids are null
{
// build model ect..
return PartialView(model);
}
EDIT: Added my AJAX request
$(document).ready(function () {
$('#spanComputerPackagesBuffer').on('click', function () {
var ids = $('#divComputerPackagesBuffer').data('buffer');
console.log('bufferIds: ' + bufferIds);
var data = {
ids: ids
};
var url = getUrlShowComputerPackageBuffer();
loadTable(url, "result", data);
});
});
// AJAX's
function loadTable(url, updateTargetId, data) {
var promise = $.ajax({
url: url,
dataType: "html",
data: data
})
.done(function (result) {
$('#' + updateTargetId).html(result);
})
.fail(function (jqXhr, textStatus, errorThrown) {
var errMsg = textStatus.toUpperCase() + ": " + errorThrown + '. Could not load HTML.';
alert(errMsg);
});
};
// URL's
function getUrlShowComputerPackageBuffer() {
return '#Url.Action("ShowComputerPackageBuffer", "Buffer")';
};
SOLUTIONS: // Thanks to #aherrick comment. I missed the good old "traditional"
$.ajax({
type: "POST",
url: '#Url.Action("ShowComputerPackageBuffer", "Buffer")',
dataType: "json",
traditional: true,
data: {
bufferIds: bufferIds
}
});

Use the traditional parameter and set it to true.
$.ajax({
type: "POST",
url: "/URL",
dataType: "json",
traditional: true,
data: {}
});

Try this one (I've checked it):
$(function () {
var ids = [1, 4, 5];
$.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: '#Url.Action("YourAction", "YourController")',
data: JSON.stringify( { ids: ids })
}).done(function () {
});
});
You have to make sure your contentType is application/json and your data is stringified.

public ActionResult SaveSomething(int[] requestData)
//or
public ActionResult SaveSomething(IEnumerable<int> requestData)
Using Action Result you cannot receive JSON object:
Using Controler:
[HttpPost]
[Route( "api/Controller/SaveSomething" )]
public object SaveTimeSheet( int[] requestData )
{
try
{
doSomethingWith( requestData );
return new
{
status = "Ok",
message = "Updated!"
};
}
catch( Exception ex )
{
return new
{
status = "Error",
message = ex.Message
};
}
}
java script:
var ids = [1,4,5];
var baseUrl: 'localhost/yourwebsite'
$.ajax({
url: baseUrl + '/api/Controller/SaveSomething',
type: 'POST',
data: JSON.stringify(ids),
dataType: 'json',
contentType: 'application/json',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
if (result != undefined) {
window.location.href = window.location.href;
}
},
async: false,
});
