I'm trying to post data into a controller but it doesn't seems to work, I need the post to include the content of the view into a div when done but I cant quite achieve it
Here's my js function:
function show(num) {
$.ajax({
dataType: "html",
type: "POST",
url: "Student/Schedule",
data: { number: num },
success: function (a) {
// Replace the div's content with the page method's return.
alert("success");
$('#schedule').load(a);
}
});
}
And, here's my controller:
public ActionResult Schedule(String number)
{
return View(number);
}
I am a noob in MVC and C#, so any help is welcome.
There are somethings that you should fix to solve the problem.
Change Url to "/Student/Schedule"
You are using "Student/Schedule" as url, so you are trying to call an action named "Student".
Add [HttpPost] to your action.
You should return PartialView("Schedule", number);.
When you use return View(number) it uses the string value of number as your view name. You should explicitly pass view name and model.
Use $('#schedule').html(a);
It's better to add an error function to your ajax call to be able to find errors:
error: function (jqXHR, textStatus, errorThrown) {
alert(errorThrown);
//or you can put jqXHR.responseText somewhere as complete response. Its html.
}
Your action should return a Partial View, not a View.
Change your action to:
[HttpPost]
// by the way use string instead of String
public ActionResult Schedule(string number)
{
return PartialView("_Schedule", number);
}
Then, you'll need to create a partial view named _Schedule.cshtml.
Also, you need to change $('#schedule').load(a); to $('#schedule').html(a); And, I'd suggest that you use a Url.Action to set your url in your ajax call, like this:
function show(num) {
$.ajax({
dataType: "html",
type: "POST",
url: '#Url.Action("Schedule", "Student")',
data: { number: num },
success: function (a) {
// Replace the div's content with the page method's return.
alert("success");
$('#schedule').html(a);
}
});
}
I had the same issue what i did was adding jquery.unobtrusive-ajax.js to my scripts

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
I have a HomeController in my ASP.NET MVC application in folder "Controllers". My View is in: "View/Home/Index.cshtml" (look at my figure below).
I am using Ajax to get some json file every a few second. Problem is in Ajax URL, because I really don't know and didn't find, how to tell that property, that it has to go back a few folders and then find the HomeController.
My Solution looks like this:
Here is a method in my HomeController:
[HttpGet]
public ActionResult GetRandomFeed()
{
Item i = ss.getRandomFeed();
return Json(new { Source = i.Media.Source, Avatar = i.User.Avatar, Text = i.Text, Name = i.User.Name }, JsonRequestBehavior.AllowGet);
}
My AJAX in the View:
setInterval(function () {
$.ajax({
type: "GET",
url: '/HomeController.cs/GetRandomFeed', // Of course I have tried a lots of attempts in here
contentType: "application/json;", // Not sure about this
dataType: "json",
success: function (response) {
console.log("Success :)");
},
error: function() {
console.log("Error!");
}
});
}, 2000);
All I want to get that JSON file (or can be even an array of strings) and use it in my Success function. It is a simple Slide Show and JSON contains the URLs that I want to show in the page every X seconds (just changing source of an image that is in that JSON file).
I couldn't find anything like this. How to use that URL correctly OR found something similiar for WebForms but cannot use it in MVC.
Change your AJAX URL declaration to:
url: '/Home/GetRandomFeed'
Remove the .cs
Or you can also do, assuming this view is under your controller:
url: '#Url.Action("GetRandomFeed")'
In my experience, it doesn't seem enter the function is just because the JSON return from the controller doesn't include Status = "OK"
[HttpGet]
public ActionResult GetRandomFeed()
{
...
...
return Json(new
{
Status = "Ok", ...
}
I've looked at several solutions for making an ajax call and by not this issue mentioned anywhere i feel it might be something specific to the environment i'm working with.
My controller:
[HttpPost]
public ActionResult ChangeDefualtCC(string a)
{
return Json("ok");
}
[HttpGet]
public ActionResult ChangeDefualtCC()
{
return Json("ok");
}
JS:
$("nevermind").change(function () {
$.ajax({
type: "POST",
url: "/Account/ChangeDefualtCC",
dataType: "json",
data: {
a: "A"
},
success: function (data) { console.log(data)},
error: function (data) { console.log("error");}
});
});
The Controller code is never hit, and this is what i'm seeing in chrome after the ajax call:
EDIT 2: The page hits the [HttpGet] method.
EDIT:
I tagged Ektron as well because it is used in the project, and it is possible that it is affecting the call.
My Routes:
Update: I have tried using Get, as well as Post, and also returning back to the View I was in, I get the 302 everytime.
any ideas?
It looks like it finds the "get" because you don't have a parameter in that call. I think you might be missing the content type from your ajax call, so the model binder cannot parse the content of your post as a parameter.
$.ajax({
type: "POST",
url: "/Account/ChangeDefualtCC",
contentType: 'application/json; charset=utf-8',
dataType: "json",
data: {
a: "A"
},
success: function (data) { console.log(data)},
error: function (data) { console.log("error");}
});
Your code seems to be absolutely correct.
This not be exact solution but try this may it work.
$("nevermind").change(function () {
$.post("/../Home/ChangeDefualtCC", { a: "A" }, function (data) {
console.log(data)
});
});
Our project is integrated with the CMS Ektron. We later discovered that Ektron is hit before the C# code, and has some affect to any url without a trailing url.
Thanks for all the help
I have a Text Box and a Select Options Multiple, i store all the selected items using knockout selectedOptions in a viewModel.
If I try to pass the captured information to my Controller using ajax I'm unable to recieve my MetricsChosenModel.
var MetricsChosenModel= window.vm.MetricsChosenModel();
var ApplicationsNameValue = $.trim($("#add-Applications").val());
if (ApplicationsNameValue.length <= 0) {
$("#text-add-Applications").popover('show');
}
$.ajax({
url: '/Admin/AddApplications',
type: "POST",
dataType: "JSON",
data: { ApplicationsName: ApplicationsNameValue, MetricsChosenModel: MetricsChosenModel },
success: function (returndata) {
if (returndata == true) {
}
else {
}
},
error: function () {
}
});
My Controller
public ActionResult AddApplications(string ApplicationsName,List<string> MetricsChosenModel)
{
//Code here
return View();
}
My MetricsChosenModel stores data in following format
MetricsChosenModel[0] => 5
MetricsChosenModel [1] => 6
why am i not able to recieve the list value of MetricsChosenModel , I'm able to recieve the ApplicationsName though,
Also it would be great if some one can explain, how am i wrong here,
Thanks,
Without knowing what your routing looks like, it's hard to pinpoint the exact source of the problem. If I had to guess, I'd say that you're getting the ApplicationsName value through the URL (routing or querystring parameter). If that's the case, you could probably add the [FromBody] attribute to the MetricsChosenModel. Note, however, that you're only allowed one FromBodyAttribute per method signature. If you need more variables, a simple solution to this problem is to create a model which contains each of the properties you're looking to receive in your controller action.
Hope that helps!
I've run into this problem myself with ASP.NET MVC: sending a model with some fields and one or more arrays up to a controller would not properly get the array contents into the C# model. The following change to the ajax call fixes it for me every time:
$.ajax({
url: '/Admin/AddApplications',
type: "POST",
contentType: 'application/json; charset=utf-8', // ADD THIS
dataType: "JSON",
data: JSON.stringify({ ApplicationsName: ApplicationsNameValue, MetricsChosenModel: MetricsChosenModel }), // Also added JSON.stringify
success: function (returndata) {
if (returndata == true) {
}
else {
}
},
error: function () {
}
});
The 'content-type' and 'JSON.stringify' help MVC with converting the model. Please let me know if that helped for you too :)
I'm using ASP.NET MVC3 with Jquery. I'm trying to pass my form elements back to the controller using something like this (Please note I removed success and error code for simplicity):
var formElements = $("#myForm").serialize();
$.ajax({
type: "POST",
url: ScriptResolveUrl("~/Report/SubmitChanges"),
data: {collection: formElements},
success:
error:
dataType: "json"
});
My question is what should the parameter in my controller method look like:
Here is my controller method:
public ActionResult SubmitChanges(WHAT GOES HERE?)
{
}
So what I'm really looking for is what should be the type of the parameter going into the controller method? I want to be able to retrieve the values of the form elements in the controller.
So here is what I did. I have about 20-30 elements on my form so I really didn't want to have to turn each one into a parameter or list them all out in the collection.
In the jquery, I did the following:
var formElements = $("#myForm").serialize();
$.ajax({
type: "POST",
url: ScriptResolveUrl("~/Report/SubmitChanges"),
data: { parms: formElements },
success:
error:
dataType: "json"
});
It then goes into my controller as a string:
public ActionResult SubmitChanges(string parms)
I then found a function to parse that string (seems to be working)
NameValueCollection qscoll = HttpUtility.ParseQueryString(parms);
This seems to work without listing out all of the form elements.
Assuming your form elements all correspond to your model (let's say it's MyModel), then it should simply be:
public ActionResult SubmitChanges(MyModel model)
{
}
MVC default model binding will do the rest :).
Make sure you change your data definition in the jQuery ajax method though, you've already serialized it. Just do:
data: formElements,
I'm assuming the following in your jQuery ajax method is a copy and paste error?
success:
error:
If it's not, then make sure you either remove it, or change them to:
success: function (result) {
//do something
},
error: function () {
//do something on error
}
The problem is that their is no model that corresponds to my form
elements.
Then you can have this:
public ActionResult SubmitChanges(int id, string name)
{
}
And then pass in the individual items:
var o = {
id = $("#id_elem_id").val(),
name = $("#name_elem_id").val()
}
$.ajax({
type: "POST",
url: ScriptResolveUrl("~/Report/SubmitChanges"),
data: JSON.stringify(o),
success:
error:
dataType: "json"
});
where id_elem_id and name_elem_id are the ids of your html elements. And add any additional parameters you need, just follow along.
You were almost there. Just get rid of the brackets around your data parameter:
var formElements = $('#myForm').serialize();
$.ajax({
type: 'POST',
url: ScriptResolveUrl("~/Report/SubmitChanges"),
data: formElements,
success: function(result) {
// handle the success of the AJAX request
},
error: function() {
// an error occurred
}
});
