From a page Index.cshtml, i have a very simple ajax call
controller1 and controller2 have the same action:
public ActionResult abc(string name)
{
return new JsonResult()
{
Data = new
{
success = true,
JsonRequestBehavior = JsonRequestBehavior.AllowGet
}
};
}
$(document).ready(function ($) {
$.ajax({
url: '#Url.Action("abc", "controller1")',
type: 'POST',
data: { name: 'John' },
dataType: 'json',
success: function (result) {
if (result.success) {
alert("ok");
}
else {
alert(result.error);
}
}
});
});
not work
however using exactly the same syntax, just change the controller, it works !!!.
abc action is the same.
$.ajax({
url: '#Url.Action("abc","controller2")',
type: 'POST',
data: { name: 'John' },
dataType: 'json',
success: function (result) {
if (result.success) {
alert("ok");
}
else {
alert(result.error);
}
}
});
it drives me crazy, don't know what happen. On a new project, i tried the same code, it works perfectly, but not on my current work.

I'm trying to POST an int with Ajax to my controller
Js
<script>
function FillCity() {
var provinceId = $(provinces).val();
$.ajax({
url: "FillCity",
type: "POST",
data: { id: provinceId },
dataType: "json",
traditional: true,
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#cities").html(""); // clear before appending new list
$.each(data, function (i, city) {
$("#cities").append(
$('<option></option>').val(city.Id).html(city.Name));
});
}
});
}
</script>
code in my controller :
[HttpPost]
public ActionResult FillCity(int id)
{
var cities = _context.City.Where(c => c.ProvinceId == 5);
return Json(cities);
}
but it always post 0 as id, I tried digits instead of provinceId, but it rtills send 0
You should create an class that have a Id Property.
public class ProvinceIdDto
{
public int Id { get; set; }
}
replace int id with ProvinceIdDto model in action
[HttpPost]
public ActionResult FillCity(ProvinceIdDto model)
{
var cities = _context.City.Where(c => c.ProvinceId == model.Id);
return Json(cities);
}
replace { id: provinceId } with JSON.stringify({ Id: provinceId }),
<script>
function FillCity() {
var provinceId = $(provinces).val();
$.ajax({
url: "FillCity",
type: "POST",
data: JSON.stringify({ Id: provinceId }),
dataType: "json",
traditional: true,
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#cities").html(""); // clear before appending new list
$.each(data, function (i, city) {
$("#cities").append(
$('<option></option>').val(city.Id).html(city.Name));
});
}
});
}
</script>
Another options is you can replace HttpPost method with HttpGet and pass id to action like this.
Change type: "POST", to type: "GET",
<script>
function FillCity() {
var provinceId = $(provinces).val();
$.ajax({
url: "FillCity?id="+provinceId,//<-- NOTE THIS
type: "GET",//<-- NOTE THIS
dataType: "json",
traditional: true,
contentType: 'application/json; charset=utf-8',
success: function (data) {
$("#cities").html(""); // clear before appending new list
$.each(data, function (i, city) {
$("#cities").append(
$('<option></option>').val(city.Id).html(city.Name));
});
}
});
}
</script>
C#
[HttpGet]
public ActionResult FillCity(int id)
{
var cities = _context.City.Where(c => c.ProvinceId == id);
return Json(cities);
}
when you do { id: provinceId } you are creating an object with property id
in your controller you are just expecting an id. You will need to ether:
A pass it as a query parameter url: "FillCity?id=" + provinceId
B create an object to be parsed from the request body.
public class Payload {
public int Id {get;set;}
}
and use it like this
public ActionResult FillCity([FromBody] Payload payload)
Can you verify this statement has a value:
var provinceId = $(provinces).val();
It's possible that isn't finding what you are looking for, and because you have the type int as a parameter, it defaults it to "0".
You shouldn't need to change it to a GET and your MVC method is fine as is. You can see from JQuery's own sample it should work:
$.ajax({
method: "POST",
url: "some.php",
data: { name: "John", location: "Boston" }
})
.done(function( msg ) {
alert( "Data Saved: " + msg );
});
I think it might not be finding the input field successfully.
I fairly new to Ajax post, and I wonder if someone could help me with why i keep getting the error message.
VideoController
[HttpPost]
public ActionResult Check(string userid, string streamid)
{
return Json(new { success = true });
}
The reason why the httppost is fairly empty yet is just to test if it works before i start writing the code.
Jquery
var userID = '#User.Identity.GetUserId()';
var defaultContext = window.location.hash === "" ? XSockets.Utils.guid() : window.location.hash.substr(1);
//alert(defaultContext);
$.ajax({
url: '/video/check',
type: 'POST',
dataType: 'json',
data: JSON.stringify({
userid: userID,
streamid: defaultContext
}),
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert(data.success);
},
error: function (error) {
alert(error.status);
}
});
I keep getting throw into my error: function and if I debug I never hit the [httpPost] Method
Can someone help
Update
I get a 404 in the alert.
RouteConfig
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
Try not to hardcore the URL:
var tURL = '#Url.Action("Check", "Video")';
$.ajax({
url: tURL ,
type: 'POST',
dataType: 'json',
data: JSON.stringify({
userid: userID,
streamid: defaultContext
}),
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert(data.success);
},
error: function () {
alert("error");
}
});
Server:
[HttpPost]
public JsonResult Foo(string userid, string streamid)
{
return new JsonResult{ Data = new {success = true}};
}
Client:
$.post('/home/foo',{userid:'123', streamid:'bar'}, function(r) {
console.log(r);
});
EDIT - If you prefer the $.ajax way instead of $.post:
$.ajax({
url: '/home/foo',
type: 'POST',
dataType: 'json',
data: JSON.stringify({
userid: '123',
streamid: 'bar'
}),
contentType: 'application/json; charset=utf-8',
success: function (data) {
alert(data.success);
},
error: function () {
alert("error");
}
});
The confusing thing is that you mix XSockets.NET with AJAX... When you have XSockets in there, why pass anything over HTTP with AJAX? You can just as easy pass it to XSockets and call your service layer from there. Just a friendly pointer.
My Jquery Ajax Call. How to return model from action to ajax and pass to another action.
function ChangeName(id)
{
var name=$("#name").val();
$.ajax({
cache:false,
url: "#Url.Action("EditName", "Order")",
data: "Name=" +name+"&Id="+id ,
type: "POST",
success: function (data) {
window.location.href=data.Url;//doesnt work passes null model
}
});
}
public ActionResult EditName(string name,int id)
{
var product= GetProduct(id);
product.Name=name;
UpdateProduct(product);
var model=new ProdModel(){id=id};
return Json(new
{
Url = Url.Action("Test","Order",new{model=model})
},JsonRequestBehavior.AllowGet);
}
public ActionResult Test(ProdModel model)//Model null
{
return RedirectToAction("List", "Product");
}
I have tried this but not getting success.
Try this
function ChangeName(id)
{
var name=$("#name").val();
var params = {
Name: name,
Id: id
};
$.ajax({
cache:false,
url: '#Url.Action("EditName", "Order")',
data: JSON.stringify(params),
type: "POST",
success: function (data) {
window.location.href=data.Url;//doesnt work passes null model
}
});
}
[HttpPost]
public ActionResult EditName(string name,int id)
{
var product= GetProduct(id);
product.Name=name;
UpdateProduct(product);
var model=new ProdModel(){id=id};
return Json(new
{
Url = Url.Action("Test","Order",new{model=product})
},JsonRequestBehavior.AllowGet);
}
Try as follows
In Edit Action try returning the model instead of url,
public josnResult EditName(string name,int id)
{
var product= GetProduct(id);
product.Name=name;
UpdateProduct(product);
var model=new ProdModel(){id=id};
return Json(model,JsonRequestBehavior.AllowGet);
}
Then in ajax Success call you can make another call to Test Action
$.ajax({
cache:false,
url: '#Url.Action("EditName", "Order")',
data: JSON.stringify(params),
type: "POST",
success: function (data) {
CallTestAction(data);
}
});
var CallTestAction = function(data) {
$.ajax({
cache:false,
url: '#Url.Action("Test", "Order")',
data: {model = data},
type: "POST",
success: function (data) {
}
});
};
I have a mobile application with MVC3 and Jquerymobile. At form submission (with ajax function) I want to display loading icon (ajax-loader.png) while submit and redirect.
Thanks!
my ajax function:
$("#add").click(function () {
$.validator.unobtrusive.parse($('form')); //added
if ($("form").valid()) {
var IDs = new Array($("#SelectedProduct").val(), $("#SelectedAccount").val(), $("#SelectedProject").val(), $("#SelectedTask").val(), $("#date").val(), $("#duration").val());
$.ajax({
url: '#Url.Action("SaveLine", "AddLine")',
type: 'post',
data: { ids: IDs },
dataType: 'json',
traditional: true,
success: function (data) {
if (data.success == true) {
$("#ajaxPostMessage").html(data.Success);
$("#ajaxPostMessage").addClass('ajaxMessage').slideDown(function () {
window.location.href = '#Url.Action("Index", "AddLine")';
}).delay(1800)
}
else {
$("#ajaxPostMessage").html(data.Error);
$("#ajaxPostMessage").addClass('ajaxMessage');
$("#ajaxPostMessage").show();
}
}
});
}
return false;
});
I would do something like this:
Ajax = {
Submit: function() {
Ajax.Loading();
//ajax stuff
//Ajax.Message('form complete, blah blah');
},
Loading: function() {
$('#ajax').html('ajax-loader.png');
},
Message: function(msg) [
$('#ajax').html(msg);
}
}
This is my jquery with json
$('#btnVerificationOk').click(function () {
var verId = $('#trans_verification_id').val();
var verCode = $('#trans_verification_code').val();
$.ajax({
url: '/Profile/CompleteTransactions',
type: 'POST',
data: { },
dataType: 'json',
success: function (result) {
alert(result);
},
error: function () {
alert('ERROR ERROR !!!!!!!!!!!!');
}
});
});
And My C# method:
[Authorize]
[HttpPost]
private JsonResult CompleteTransactions()
{
return Json("Done");
}
Its always alerts 'ERROR ERROR !!!!!!!!!!!!' i tried debugging but CompleteTransactions method is not firing
And this is my second json which is bellow and works good
$('#btnTransfareOk').click(function () {
var userName = $('#transfare_username').val();
var amount = $('#transfare_amount').val();
if (userName == '' || amount == '') {
$('#transfare_error_list').html('Please fill boxes.');
} else {
$.ajax({
url: '/Profile/TranfareMoney',
type: 'POST',
data: { ToUsername: userName, Amount: amount },
dataType: 'json',
success: function (result) {
$('#transfare_error_list').html(result.text);
$('#trans_verification_id').val(result.id);
$('#transfare_username').val("");
$('#transfare_amount').val("");
},
error: function () {
$('#transfare_error_list').html('Oops... Error.');
}
});
}
});
I'm not 100% sure, but shouldn't you controller action handler be public ?
