I have the following code in my MVC controller:
[HttpPost]
public PartialViewResult GetPartialDiv(int id /* drop down value */)
{
PartyInvites.Models.GuestResponse guestResponse = new PartyInvites.Models.GuestResponse();
guestResponse.Name = "this was generated from this ddl id:";
return PartialView("MyPartialView", guestResponse);
}
Then this in my javascript at the top of my view:
$(document).ready(function () {
$(".SelectedCustomer").change( function (event) {
$.ajax({
url: "#Url.Action("GetPartialDiv/")" + $(this).val(),
data: { id : $(this).val() /* add other additional parameters */ },
cache: false,
type: "POST",
dataType: "html",
success: function (data, textStatus, XMLHttpRequest) {
SetData(data);
}
});
});
function SetData(data)
{
$("#divPartialView").html( data ); // HTML DOM replace
}
});
Then finally my html:
<div id="divPartialView">
#Html.Partial("~/Views/MyPartialView.cshtml", Model)
</div>
Essentially when a my dropdown tag (which has a class called SelectedCustomer) has an onchange fired it should fire the post call. Which it does and I can debug into my controller and it even goes back successfully passes back the PartialViewResult but then the success SetData() function doesnt get called and instead I get a 500 internal server error as below on Google CHromes console:
POST http:// localhost:45108/Home/GetPartialDiv/1 500 (Internal Server
Error) jquery-1.9.1.min.js:5 b.ajaxTransport.send
jquery-1.9.1.min.js:5 b.extend.ajax jquery-1.9.1.min.js:5 (anonymous
function) 5:25 b.event.dispatch jquery-1.9.1.min.js:3
b.event.add.v.handle jquery-1.9.1.min.js:3
Any ideas what I'm doing wrong? I've googled this one to death!
this line is not true: url: "#Url.Action("GetPartialDiv/")" + $(this).val(),
$.ajax data attribute is already included route value. So just define url in url attribute. write route value in data attribute.
$(".SelectedCustomer").change( function (event) {
$.ajax({
url: '#Url.Action("GetPartialDiv", "Home")',
data: { id : $(this).val() /* add other additional parameters */ },
cache: false,
type: "POST",
dataType: "html",
success: function (data, textStatus, XMLHttpRequest) {
SetData(data);
}
});
});

I'm using net.core for the first time today and I'm trying to call an action method from an ajax call:
My Ajax call (from a normal HTML page)
$("#contactMap").click(function (e) {
e.preventDefault();
var url = "/MapObjects/mapContact";
//I've tried MapObjectsController & '#Url.Action("mapContact", 'MapObjects")'; But to no avail
$.ajax({
url: url,
type: 'POST',
contentType: 'application/json; charset=utf-8',
cache: false,
success: function (result) {
alert("success");
}
});
});
And in my controller:
namespace myName.Controllers
{
public class MapObjectsController : Controller
{
public IActionResult Index()
{
return View();
}
[HttpPost]
public JsonResult mapContact()
{
Account account = new Account();
return Json(account);
}
}
}
The 'account' is just a normal model (obvs empty in this case). All I receive is a 404 error in the console though.
As mentioned this is the 1st time I've .net Core (this is code I've written loads of times in 'normal' MVC projects) so it's possible that I'm missing something really obvious.
Thanks,

The first, try to call the #Url.Action() explicitly in the Ajax call :
$("#contactMap").click(function (e) {
e.preventDefault();
$.ajax({
url: '#Url.Action("mapContact", "MapObjects")',
type: 'POST',
contentType: 'application/json; charset=utf-8',
cache: false,
success: function (result) {
alert("success");
}
});
});
The second, check your routing rules.
In my MVC application I don't want the layout page to reload everytime a view is selected. It would be great if the views could be loaded using ajax to keep things nice and fast and allow me to persist certain interface states that are wiped out when you move around.
My initial approach was to add some ajax to the _Layout.cshtml and then whent he view was requested pass that request to the controller method which will grab that page. All I ended up doing however was returning the WHOLE view again.
Here is the code I have so far, am I on the right tracks here or is this totally wrong?
Layout Ajax Script
<script>
$(function () {
var content = document.getElementById('content');
//When a user selects a link, pass the data attribute and
//use it to construct the url
$('#sidebar a').on("click", function () {
var page = $(this).data('page');
console.log("Data Attrib : " + page);
$.ajax({
type: 'GET',
url: '#Url.Content("~/Home/")' + page,
success: function (data) {
$('#content').html(data);
console.log("Success");
},
error: function (xhr, ajaxOptions, thrownError) {
console.log("Error: " + thrownError);
}
})
})
});
</script>
As I say, this sort of works, but it's not perfect as it returns the whole page into the content area including layout, ideally I just want the core view data.
you can create a Single Page Application that have 1 layout and in home controller and index action method create menu or user setting or another things
and now you can load other action with Ajax call with data-content html that does not have layout file and append that in container
when user click another menu clean older content and add new or you can create tab strip or window
Layout.cshtml
<script>
$(function () {
//When a user selects a link, pass the data attribute and
//use it to construct the url
$('#sidebar a').on("click", function () {
var page = $(this).data('page');
$.ajax({
type: 'POST',
url: '/Home/Pages',
data: { pageValue: page },
success: function (data) {
$('#content').html(data);
console.log("Success");
},
error: function (xhr, ajaxOptions, thrownError) {
console.log("Error: " + thrownError);
}
})
})
});
Controller
public class HomeController : Controller
{
[HttpPost]
public string Pages(string pageValue)
{
string result = //Whatever
return result;
}
}
Controller
public ActionResult SomeAction(String someparams)
{
//Make the model
SomeModel someModel = new SomeModel();
someModel.someparams = someparams;
return PartialView("SomePartialView", someModel);
}
In View
$.ajax({
url: "/Home/SomeAction",
type: "POST",
dataType : "html",
data: json,
contentType: 'application/json; charset=utf-8',
success: function(data){
$('#SomeDivID').html(data);
}
});
I have a few checkboxes on my page. I have some jquery in place to ensure that only one checkbox is checked at a time. I have assigned a specific value to each checkbox. The below ajax finds the checkbox that is checked and I'm grabbing the value associated to it. How do I pass that value to my action?
AJAX
$("input:checkbox").click(function () {
var PaymentID = document.querySelector('#chkBox:checked').value;
alert(PaymentID); // for test
$.ajax({
type: "POST",
dataType: "json",
data: PaymentID,
contentType: "application/json; charset=utf-8",
url: "#Url.Action("MyAction", "Home")",
success: function () {
return PaymentID; // Failed attempt at passing data.
}
})
})
Action:
[HttpPost]
public ActionResult MyAction(string PaymentID)
{
// Magic
}
Please keep in mind i am fairly new to ajax. Thx guys.
You can pass a javascript object with name PaymentID ( same name as your action method parameter)
data: { PaymentID: PaymentID },
You do not need to specify contentType as you are sending a simply object. Also you do not necessarily need to specify dataType for your ajax call to send the data.
This should work.
var PaymentID = "some value";
$.ajax({
type: "POST",
data: { PaymentID: PaymentID },
url: "#Url.Action("MyAction", "Home")",
success: function (response) {
console.log('response', response);
}
});
Or you can use the $.post method.
$.post("#Url.Action("MyAction", "Home")",{ PaymentID: PaymentID }, function(response) {
console.log('response', response);
});
I have a one Edit.cshtml page and there is 1 partial template call. in that template I make an ajax call and my controller is home and action name is savedata
ajax function
$.ajax({
url: "CountryZone/SaveData",
type: 'POST',
data: { data: selectedID, id: id },
dataType: "html",
success: function (result) {
alert("Success");
},
error: function (result) {
data.str = null;
alert("Error");
},
});
controller:--
public ActionResult Savedata(string data, int CountryZoneId)
{
return null;
}
now when my ajax call is going
there is url wrong :--- url is Home/edit/Home/Savedata instead of this there is only Home/SaveData
It's a bad idea to hardcode urls in MVC application.
Change this line:
url: "CountryZone/SaveData",
To this:
url: "/CountryZone/SaveData",
I suggest at least using Url.Action in the view and storing it in the js variable.
Use standard MVC code as below:
url: '#Url.Action("SaveData","CountryZone")',
Full Code
$.ajax({
url: '#Url.Action("SaveData","CountryZone")',
type: 'POST',
data: { data: selectedID, CountryZoneId: id },
dataType: "html",
success: function (result) {
alert("Success");
},
error: function (result) {
data.str = null;
alert("Error");
},
});
[HttpPost]
public ActionResult Savedata(string data, int CountryZoneId)
{
return null;
}
I'm trying to create my first REST application with the web api in mvc4. I have a controller set up with the HttpPost verb but for some reason when I click the link to post the xml string to the controller I get an error - "{"Message":"No HTTP resource was found that matches the request URI '/api/Apply/ApplyToJob'.","MessageDetail":"No action was found on the controller 'Apply' that matches the request."}" Any ideas what I might be doing wrong? Here's the view page...
Post Data
<script type="text/javascript">
window.onload = function () {
$("#lnkPost").on("click", function () {
$.get("/TestResponse.xml", function (d) {
$.ajax({
//contentType: "text/xml",
//dataType: "xml",
type: "post",
url: "/api/Apply/ApplyToJob",
data: {
"strXml": (new XMLSerializer()).serializeToString(d)
},
success: function () { console.log('success'); }
});
});
});
};
</script>
and here's the controller.
public class ApplyController : ApiController
{
[HttpPost]
[ActionName("ApplyToJob")]
public string ApplyToJob(string strXml)
{
return "success";
}
}
Modify your action's parameter like below:
public string ApplyToJob([FromBody]string strXml)
This is because without this FromBody attribute, the string parameter is expected to come from the Uri. Since you do not have it in the Uri the action selection is failing.
Also, looking at your client code, shouldn't you set the appropriate content type header in your request?
Edited:
You can modify your javascript to like below and see if it works:
$.ajax({ contentType: "text/xml",
dataType: "xml",
type: "post",
url: "/api/values",
data: "your raw xml data here",
success: function () { console.log('success'); }
});
