First of all I looked trough a lot of same questions on stack. My problem is as follows:
I'm working on a school project to make a card game (ginrummy)
In this web application (mvc 4) I want to move cards to sets (right side) and I want to do this with ajax.
added a picture to clearify.
The ajax perfectly triggers the controller and perfectly bring over the data I put through.
In firebug I checked the response and it even added a card to the right correct set
The problem is when the ajax is done, it doesn't trigger the succes function neither it updates the page.
Note: This is my first time I work with ajax.
The complete function returns OK status.
Now the code:
View:
var GameId = #Model.Id
$(function () {
$(".droppable").droppable({
drop: function (event, ui) {
var id = ui.draggable.find("a").attr("data-CardId");
var location = droppableId = $(this).attr("id");
$.ajax({
type: "POST",
url: '#Url.Action("ChangeCardLocation")',
data: { 'id': GameId, 'cardId': id, 'location': location },
succes: function () {
alert('wow');
},
complete:function (){
}
});
}
});
});
Controller:
public ActionResult ChangeCardLocation(int id, int cardId, Location location)
{
var game = db.Games.Find(id);
var card = db.Cards.Find(cardId);
game.ChangeCardLocationTo(card, location);
db.SaveChanges();
game.Info = game.GetInfo(id);
if (game.GameState == GameState.playerOneLayOn || game.GameState == GameState.playerTwoLayOn)
{
return View("LastTurn", game);
}
else
{
return View("Details", game);
}
}
Any suggestions on what is going wrong?
I'm a student and it is for a school project!
#comment:
When I did this:
error: function(xhr, error){
console.log(error);
console.log(xhr);
},
I noticed it didn't get triggerd.
After that I tried the same in complete:
complete:function (xhr, error){
console.log(error);
console.log(xhr);
}
The result was
succes
object that returned readystate 4
I misspelled success thats in the first part it wasn't working. But my next question is how do make it updating the contents of the page that the ajax call is getting back.
I am trying myself offcourse now. In the data succes is getting is my whole page delivered as I want to have it.
Is it because you have misspelt "success"?
$.ajax({
type: "POST",
url: '#Url.Action("ChangeCardLocation")',
data: { 'id': GameId, 'cardId': id, 'location': location },
success: function () {
alert('wow');
},
complete:function (){
}
});

I want to update a div with the minute of the match on my page every 15 seconds. How can i do that ? I just want to refresh the area where that div is.
<script>
setInterval(function () {
$.ajax({
#*url: '#Url.Action("_List", "Home",new { match_id=Model.match.match_id})',*#
cache: false,
success: function (result) {
$("#test").html(result);
console.log(result)
//alert(result);
}
});
}, 20000);
</script>
Use partial views for this. They will allow you to update only a part of the DOM without having to perform a full page refresh or a postback and they are strongly typed.
For example I created below partial view
function loadPartialView() {
$.ajax({
url: "#Url.Action("ActionName", "ControllerName")",
type: 'GET', // <-- make a async request by GET
dataType: 'html', // <-- to expect an html response
success: function(result) {
$('#YourDiv').html(result);
}
});
}
$(function() {
loadPartialView(); // first time
// re-call the function each 5 seconds
window.setInterval("loadPartialView()", 5000);
});
After every 5 seconds it goes to controller and executes the action
public class ControllerName: Controller
{
public ActionResult ActionName()
{
.
. // code for update object
.
return PartialView("PartialViewName", updatedObject);
}
}

I have been following this tutorial https://www.youtube.com/watch?v=c_MELPfxJug regarding ajax and JsonResult in HomeController
I did the tutorial, however for some reason the controller is returning Html and not json
I did not change one line of code, but it's failing with parseError on the javascript side.
when i look at the response i see an html page, not a json object.
Controller code:
public JsonResult DoubleValue(int? Value)
{
if (!Request.IsAjaxRequest() || !Value.HasValue)
{ return null; }
else
{
int DoubleValue = Value.Value * 2;
var ret = new JsonResult
{
Data =
new { DoubleValue = DoubleValue }
};
return ret;
}
}
cshtml:
#using (Html.BeginForm())
{
#Html.TextBox("txtAmount",0)
<button id="btnDoubleValue">DoubleIT</button>
<div id="lblMessage"></div>
}
#section Scripts{
<script type="text/javascript">
$(function () {
$('#btnDoubleValue').on('click', function() {
$.ajax({
type: 'POST',
url: '#Html.Action("DoubleValue")',
data: { 'Value': $('#txtAmount').val() },
datatype: 'json',
cache: 'false'
}).success(function (data) {
var t = data;
$('#txtAmount').val(data.DoubleValue);
}).error(function (x, o, e) {
$('#lblMessage').html('error was found: ' );
});
return false;
})
});
</script>
}
found the error
I was using Html.Action and not Url.Action -> just human error I suppose
from the reference:
Html.Action - returns the result as an HTML string.
It works now
$.ajax({
type: 'POST',
url: '#Url.Action("DoubleValue")', //<--- Url.Action
data: { 'Value': $('#txtAmount').val() },
datatype: 'json',
cache: 'false'
I guess this must be the default error page, you are probably getting a 500 response and you must use the Network tab of your browser to see the real problem.
In your browser open developer tools using F12 key and navigate to Network tab.
Make the appropriate actions to do the ajax request (click on that button)
Click on the request row
Navigate to Response tab.
From there you can watch the real request your ajax does and the response from the server.
I an working on returning view from controller to jquery ,View is returned but i want to extract div from returned view.My Current code is like this
public ActionResult DeleteItem(int pid)
{
//my logic goes here
retutn View("SomeView",model);
}
Jquery
enter code here
script type="text/javascript">
$(document).ready(function () {
$('.Remove').click(function () {
var value = $(this).attr('id');
$.ajax({
cache:true,
type: "POST",
url: "#(Url.Action("DeleteItem", "ControllerName"))",
data: "pid=" + value,
success: function (data) {
$("body").html(data);
},
error:function (xhr, ajaxOptions, thrownError){
alert('Failed to subscribe.');
},
complete: function() { }
});
return false;
});
});
</script>
My current logic returns view and assign total view i.e html+body to body part of page ,which shows html part two times.Is there any way to retrieve div from the returned view and reload it.
thanx in advance
Your controller action should return a PartialViewResult otherwise it will return your layout page in the response. If you want to cater for both scenarios you can check whether the request is an AJAX request:
public ActionResult DeleteItem(int id) {
// delete your item
if (Request.IsAjaxRequest()) {
// return just the partial view
return PartialView("yourview");
}
// otherwise handle normally
return RedirectToAction("list");
}
To understand the difference between returning View and returning PartialView please see What's the difference between "return View()" and "return PartialView()".
script type="text/javascript">
$(document).ready(function () {
$('.Remove').click(function () {
var value = $(this).attr('id');
$.ajax({
cache:true,
type: "POST",
url: "#(Url.Action("DeleteItem", "ControllerName"))",
data: "pid=" + value,
success: function (data) {
var t=$(data).find('.divtoreplacewith');
$('.divtoreplace').replaceWith(d);
//Wasted my 2 days for above two lines.But satisfied with solution,
//Both div are same but '.divtoreplacewith' is having new data,And I have replaced div with that div that's all
},
error:function (xhr, ajaxOptions, thrownError){
alert('Failed to subscribe.');
},
complete: function() { }
});
return false;
});
});
I'm struggling to return a view or partial view with Ajax. Whenever I change the return type to something that isn't JSon the ajax command never succeeds. I need to return a partial view because I want to return a lot of data back.
This is my current code:
(Controller)
[HttpPost]
public ActionResult AjaxTestController(string Input)
{
string Results = Input + " -- TestTestTest";
return PartialView("Test", Results);
//return new JsonResult() { };
}
(View)
function AjaxTest() {
alert("test");
$.ajax({
type: "POST",
url: "Home/AjaxTestController",
data: "Input=Test11111",
success: function () {
alert("Success!");
}
});
Thanks!
You can use the $.post command for that:
function AjaxTest() {
alert("test");
$.post({
url: "Home/AjaxTestController",
data: "Input=Test11111",
success: function (response) {
alert(response);
}
});
try the following:
$(function () {
$('#submit').live('click', function () {
AjaxTest();
});
});
function AjaxTest() {
$.ajax({
type: "POST",
url: '#Url.Action("AjaxTestController", "Home")',
data: { Input: "Test - " + new Date() },
success: function (data) {
$('#partialResult').html(data);
},
error: function (xhr, err) {
alert(xhr.responseText);
}
});
};
inside your view and ensure that you have your target div set up for the partial to be populated into:
<div id="partialResult"></div>
also, for the example above, I added a button to the view to initiate the ajax (purely for testing):
<input type="button" value="Submit" id="submit" />
your 'partialview' should look something like this:
#model string
<h2>
Partial Test</h2>
<p>
#Model
</p>
no other changes are required to the existing action for this to now function as required.
[UPDATE] - I changed the AjaxTest() method to include the error event (the result of which is captured in an alert). hopefully, this may help further.
partial View is different than view you have to specify the whole path to the partial view or have it in share folder. otherwise is going to return not found and never success. any way this always work for me, try
partialView("~/Views/ControllerView/Test.cshtml")
I have a jQuery autoselect box displaying the correct data. Now I would like to fire an ASP.NET MVC 3 controller when an item is selected. The controller should then redirect to a View. Here's my jQuery autocomplete code (I'm sure something is missing in the 2nd Ajax call, but I haven't found it yet):
<script type="text/javascript">
$(function () {
$("#Client").autocomplete({
source: function (request, response) {
$.ajax({
url: 'Entity/GetClientAutoComplete', type: 'POST', dataType: 'json',
data: { query: request.term },
success: function (data) {
response($.map(data, function (item) {
return { label: item, value: item };
}))
}
})
},
minLength: 1,
select: function (event, ui) {
$.ajax({
url: 'Entity/GetApplicationsByName/' + ui.item.value, type: 'POST'
})
}
});
});
</script>
And here's the controller I'm trying to call:
public ActionResult GetApplicationsByName(string id)
{
ViewBag.Client = id;
var apps = _service.GetDashboardByName(id);
return View("Dashboard", apps.ToList());
}
When I watch the Ajax call fire in Firebug, I see the correct URL configuration, but nothing else happens. It's acting as though it wants to load something rather than send something. I'm confused. Thank you for any guidance.
Well you sent an id by POST to the GetApplicationsByName controller and the controller is sending back the view.
If you want redirection, you can use the following:
select: function (event, ui) {
window.location.href = 'Entity/GetApplicationsByName/' + ui.item.value;
}
