I'm sending some json data with ajax by post
function SendF() {
$.ajax({
url: '#Url.Action("Summary")',
type: 'POST',
data: JSON.stringify(flags),
contentType: "application/json;charset=utf-8",
success: function() {
},
error: function() {
alert("Oops! We've experienced a connection problem!");
}
});
}
to my controller
[HttpPost]
public ActionResult Summary(List<string> flagsChecked)
{
[...]
return View(flags);
}
and tried returning a view with data I've processed, but I guess it's not gonna happen since ajax is all about asynchronous http requests. How do I change my code to be synchronous?
The whole idea behind using ajax is to give the user the partial page update experience. If you are making an ajax call and once that is done and you are doing a redirect to another page, it does not give the partial page update experience to user. It looks very similar to the normal form submit(full page submit).
If you absolutely have to send the data to server via ajax , but want to do the redirect after the ajax call is successfully finished, you can do that using javascript in the success or done callback event on the $.ajax method.
All you have to do is, set the location.href property to the new url.
var flags = ["aa", "bb", "cc"];
$.ajax({
url: '#Url.Action("Summary")',
type: 'POST',
data: JSON.stringify(flags),
contentType: "application/json;charset=utf-8"
}).done(function(res) {
window.location.href = res.newUrl;
}).fail(function(xhr, a, error) {
console.log(error);
});
This assumes that your server action method returns a JSON response with the newUrl property which contains the url you want to redirect to .
[HttpPost]
public ActionResult Summary(List<string> flagsChecked)
{
return Json(new { newUrl = Url.Action("Index","Home") });
}
One way to do this would be to send the request to the controller via ajax and then render a partial view on your page. The easiest way would be to use the built in ajax helpers in ASP MVC. Here is a link to another post that gives a pretty good overview:

I have seen lots of questions regarding this issue but none of those resolved my problem.
My problem: my redirect action method hits the method I am redirected to, but the view stays on the same page it never changes to the redirected one.
From my Index.chstml I am creating a partial view.
From that partial view using AJAX I am submitting a request to my controller. AJAX code is below
$.ajax({
method: 'POST',
url: "/Home/SubmitTest",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(arr),
success: function (response) {
}
});
My controller code is here. I am receiving data from AJAX method and performing some jobs. In the end, I am trying to redirect the user to another method.
[HttpPost]
public IActionResult SubmitTest([FromBody] List<TestSubmitViewModel> data)
{
// Rest of the code goes here
return RedirectToAction(nameof(PipelineList));
}
The method I am redirecting to is below. Both methods are in the same controller. After redirection, I am getting hit to this method. But my view still stays in the previous URL which is
https://localhost:44339/Home/Index
but it supposed to redirected to
https://localhost:44339/Home/PipelineList
Code:
[HttpGet]
[AllowAnonymous]
public async Task<IActionResult> PipelineList()
{
List<PipelineViewModel> itemList = new List<PipelineViewModel>();
/// my other code goes here
return View(itemList);
}
Note: my PipelineList() works fine when I am coming to this action method directly from UI. What am I doing wrong here and what can I do to redirect to the URL?
I am using .NET Core 5.
Here is my routing information from StartUp.cs:
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller}/{action}/{id?}",
defaults: new { controller = "Home", action="SignIn"});
});
UPDATE
Thank you guys for pointing out the problem I was having.
Using AJAX was necessary for me to pass the selected values (which were from a table created by JS) from UI.
Finally, I made it work by changing my Controller and AJAX code.
Updated Controller:
[HttpPost]
public async Task<JsonResult> SubmitTest([FromBody]
List<TestSubmitViewModel> data)
{
try
{
// my codes goes here
return Json(new {StatusCode = statusCode });
}
catch (Exception)
{
return Json(new {StatusCode = 500 });
}
}
Updated AJAX:
$.ajax({
method: 'POST',
url: "/Home/SubmitTest",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(arr),
success: function (response) {
if (response.statusCode == 200) {
var url = "/GitLab/PipelineList";
window.location.href = url;
} else {
alert("error");
}
}
});
I know this might not be the best solution but for now, it did work. Thanks a lot to #Sergey and #Filipe
As #Sergey says, you used the wrong senior for ajax. Ajax is normally used when you want to update part of the page instead of refreshing the whole page to increase the customer experience and page load speed. If you want to redirect to another page and there is no other specific reason, there is no need to use ajax.
You could find the ajax server has returned the right 302 redirect to the client side and it redirect to the new page:
The right way is directly redirect to the new page like this:
<form asp-action="SubmitTest" asp-controller="Home" method="post">
#*Other input value you want to submit*#
<input type="submit" value="Click"/>
</form>
Result:
I am using C# ASP.NET MVC and wish to know is there any way to redirect to other page from controller in success condition. For failure condition, it should return JSon result redirect to AJAX method. For this, ActionResult return type is okay for me.
C# Controller:
[HttpPost]
public ActionResult DoMyAction(string var1, string var2)
{
// Do some action
if(success)
Redirect to a page.
else
return Json(new { Message = "Action cannot be process..", Status = false});
}
AJAX method:
$.ajax({
url: '/Home/DoMyAction',
type: 'POST',
data: { "var1": "Hello", "var2":"World!"},
datatype: "json",
contenttype: "application/json; charset=utf-8",
success: function (result) {
if (!result.Status)
// Display error message.
},
error: function () {
}
});
Note: Please do not consider syntax here, I wish to know only the way to redirect from C# controller class.
Thanks in advance!
If you want to redirect to a page using js you can use
window.location.href = 'your url here'
Hope that help.
You Need to add this in your success callback or else a normal form submit can be used
net mvc5 form and Using checkbox.
My condition is i need to Call HTTPPOST action immedaitely after selecting the checkbox(true)
Its something like HTTPPOST action should be called immediately after selecting the checkbox.
I need to pass Model as well to the HTTP Post.
can you please let me know whats the desired way to get this done ?
I'd recommend using jquery to achieve this. Assuming your checkbox is nested in a form, you can use:
$(function () {
$('#CheckBoxName').change(function () {
$(this).closest("form")[0].submit();
});
});
This will trigger a postback, calling the appropriate HttpPost method and sending the model as a parameter.
You should use javascript to react on a change of the checkbox then posting via ajax.
Here is an exemple :
$('#checkbox').change(function(){
if (this.checked){
var jsonModel = '#Html.Raw(Json.Encode(Model))';
$.ajax({
type: 'post',
url: '#Url.Action("UrlOfPostAction")',
data: { Model: jsonModel},
dataType: 'json',
success: function (res) {
//Do something
}
//manage errors
});
}
});
So basically I'm trying to show some Profile Data in my MVC Application.
Right now, everytime I click on a date on my Telerik Kendo Calendar, I can refresh the whole page and update the data I want.
However, instead of refreshing the whole I just want to refresh the partial views that shows only the data that updates after selecting the date.
Index.cshtml
<!--CODE-->
#Html.Partial("_WorkingTimeData")
<!--CODE-->
_WorkingTimeData.cshtml
var workedTime = ViewData["WorkedTimeToday"];
var hoursPerDay = ViewData["HoursPerDayContract"];
<p>You worked #workedTime hours</p>
<p>Hours Per Day (Contract) #hoursPerDay Hours</p>
Yes, right now I'm ViewDatas and it works.
This is the ajax code in Index.cshtml
$.ajax({ url: '/Profile/Index',
dataType: "json",
type: "POST",
data: JSON.stringify(10),
success: function(returl){
alert('It worked');
location.href=returl.Url;
},
error: function(jqXHR,responseText,textStatus){ alert(jqXHR.responseText) } });
Controller
[HttpPost]
public ActionResult Index(string number){
//THINGS TO DO
var redirectUrl = new UrlHelper(Request.RequestContext).Action("Index", "Profile");
return Json(new { Url = redirectUrl });
}
Well I'm very new to this, and I've been doing my research. However I still have some questions:
- Do I need to create a post method for _WorkingTimeData instead of Index like I have?
- Do I need to create a ViewModel for the Partial View?
Thanks
EDIT NUMBER 2 FOR VISHAL:
This didn't work at all, not even an alert, because, strangely, it doesn't recognise the calendar...
$("#calendar").kendoCalendar({
change : function() {
$.ajax({
url: "/Profile/WorkingTimeData",
type: "get"
}).done(function(data) {
$("#profile-timeline").html(data);
});
}});
It says $("#calendar").kendoCalendar is not a function (Telerik says that it's this way)
As for this, it reached the controller but didn't update anything:
function change() {
alert("Escolheste outro dia");
var calendar = $("#calendar").data("kendoCalendar");
var current = calendar.current();
alert(current);
$.ajax({
url: "/Profile/WorkingTimeData",
type: "get"
}).done(function(data) {
$("#profile-timeline").html(data);
});
}
I think it's because of the profile-timeline... It's a div in my view
Do I need to create a post method for _WorkingTimeData?
Yes, you need to create. But, Get would be fine too.
Do I need to create a ViewModel for the Partial View?
Not needed. If required you can create.
But, by looking at your partial view you are just using ViewData[""]. So, you need not to create any ViewModel.
Just create a method in Controller returning _WorkingTimeData PartialView.
And call that method by JQuery ajax on your DatePicker change event and replace the contents of the Div.
For example.
Controller
public PartialViewResult WorkingTimeData()
{
ViewData["WorkedTimeToday"]="NEW VALUE";
ViewData["HoursPerDayContract"] = "NEW VALUE";
return this.PartialView("_WorkingTimeData");
}
JavaScript
$("DATEPICKERELEMENT").change(function() {
$.ajax({
url: "/CONTROLLER/WorkingTimeData",
type: "get"
}).done(function(data) {
alert(data);
$("#divisionIdContainingPartialView").html(data);
}).fail(function() {
alert('error');
});
});
I wrote a post that details why you need to break the logic of thinking about partial views client-side. If you're interested you can find it here.
The TL;DR version is simply, all you have client-side is HTML. There's no knowledge about what was or was not rendered to the response via a partial view. As a result, the real question is "How do I change a portion of my HTML page based on an AJAX response?". In the simplest form, you simply select some element on the page and then alter its inner HTML. You can do that with some custom HTML created client-side or you can actually pass back an HTML document as your AJAX response and then insert that.
Experts,
I have form data -
var formdata = JSON.stringify($('#emailrequest').serializeArray());
and a url -
var urlofRequest = window.location.href; //This url is of above Emailrequest form .
My question is -
How do we send these two - formdata and urlofRequest to a .cs(controller) method -
public JsonResult ProcessEmailrequest()
{
// What code and parameters?
}
The controller method which opens up the form is -
public ActionResult EmailRequest()
{
return View();
}
I have the below code but it does not seems to work -
$.ajax({
url: sitePath + 'supply-chain-pressure/ProcessEmailrequest',
type: 'GET',
data: formdata,
sucess: function (data) {
alert('DataPosted');
}
})
The type in the ajax call is GET; no data is being posted to the form. Try making it a post or put. example jquery ajax post Also keep in mind that you are posting form data, so you will need to have parameters on the post method ProcessEmailrequest on the supply-chain-pressure controller to catch the data. example of mvc post method This is a jquery/ajax example that does basically the same thing jquery/ajax example
