In development I make an Ajax post which works in development. However when I put it on the Test server it doesn't work because IIS has assigned the application a subfolder, and this is missing in my development environment.
I have found work around (see below) but I am the first to admit this should not be the solution, as I have to remember to call a function for the url everytime I make an Ajax call.
There must be a better way.
However the code will show you what I am fixing;
function OperationsManagerFlagClickFunc(userId) {
$.ajax({
url: GetUrl("/Users/UpdateOperationsManagerFlag"),
type: "POST",
data: { "userId": userId },
success: function (data) { }
});
}
function GetUrl(path) {
var pathArray = window.location.pathname.split('/');
if (pathArray[1] === "ITOC")
return "/ITOC" + path;
else
return path;
}
If you have your javascript in .aspx file, you can generate url like this:
function OperationsManagerFlagClickFunc(userId) {
$.ajax({
url: "<%= Url.Action("UpdateOperationsManagerFlag","User") %>",
type: "POST",
data: { "userId": userId },
success: function (data) { }
});
}
Why not have a variable defined separately, like siteUrl, that will hold your site's url, with different values on the 2 servers?
Then just do:
url: siteUrl + "/Users/UpdateOperationsManagerFlag"

I have a couple of variations on the ajax depending on the flow of interactions on the page. But it's only the variables that changes. here is one of them:
$('#btn_skickaEnkel').bind('click', function () {
$.ajax({
type: 'POST',
url: '/Contact/IntresseAnmälan/',
dataType: 'json',
data: {
Namn: $('#namn').val(),
Mail: $('#mail').val(),
Info: $('#meddelande').val(),
Nivå: $('#nivå').find(":selected").text(),
IsEnkel: true,
Telefon: $('#nr').val(),
ID: function () {
var url = window.location.pathname;
var id = url.substring(url.lastIndexOf('/') + 1);
return id;
}
},
traditional: true
});
});
In my controller i am unable to redirect or return a different view. At this point the data from JSON is no longer relevant because it's already been saved to DB.
My Controller:
public ActionResult IntresseAnmälan(BokningContainer bokning)
{
db = new DbContext();
//Saving some data to database(removed)
//Just determening the state of container obj.
if (bokning.IsEnkel)
{
//Geting som information from db (removed)
//Creating a mail (removed)
email.Send(bokning.Namn, bokning.Mail, body);
}
else
{
}
//db.SaveChanges();
//This part is not working, I think it's beacuase of the Ajax
return View("IntresseAnmälan");
}
The view is not rendered and I think it's related to the ajax. The view is simply not rendered. Is there some way to force returning it and ignoring the ajax? As I said the data is no longer needed because the content is already saved to the DB.
You cannot render view on ajax call,simply you can use form post method or just redirect it to desired action on "succcess" of ajax call as below:
$('#btn_skickaEnkel').bind('click', function () {
$.ajax({
type: 'POST',
url: '/Contact/IntresseAnmälan/',
dataType: 'json',
data: {
Namn: $('#namn').val(),
Mail: $('#mail').val(),
Info: $('#meddelande').val(),
Nivå: $('#nivå').find(":selected").text(),
IsEnkel: true,
Telefon: $('#nr').val(),
ID: function () {
var url = window.location.pathname;
var id = url.substring(url.lastIndexOf('/') + 1);
return id;
}
},
traditional: true,
success: function(result) {
window.location.href = '#Url.Action("action", "Controller")';
}
});
});
I couldn't believe my eyes when I figured out this "Bugg". The problem was that I, at some point, changed the submit to a button. So the form was never submiting. Well, at least I learnt a bit about views and Ajax.
Sorry for taking your time.
I am trying to make an API call with ajax:
svc.authenticateAdmin = function (id, code) {
$.ajax({
url: 'api/event/authenticate',
data: { 'id': id, 'code': code },
datatype: 'json',
contentType: 'application/json',
type: 'GET',
success: function (data) {
App.eventBus.publish('authenticationComplete', data);
}
});
};
The method in the API Controller:
[ActionName("All")]
public bool Authenticate(int id, string code)
{
var repo = new MongoRepository<Event>(_connectionString);
var entry = repo.FirstOrDefault(e => e.Id == id);
return entry.AdminPassword == code;
}
But I am getting a 404 error: urlstuff/api/event/authenticate?id=123&code=abc 404 (Not Found)
I have copied the implementation from a number of known working calls (that I did not write). That look like:
svc.getEventFromCode = function (code) {
$.ajax({
url: '/api/event/',
data: { 'code': code },
dataType: 'json',
type: 'GET',
success: function (data) {
App.eventBus.publish('loadedEvent', data);
App.eventBus.publish('errorEventCodeExists');
},
error: function () {
App.eventBus.publish('eventNotFound', code);
}
});
};
and
svc.getEventPage = function (pageNumber) {
$.ajax({
url: '/api/event/page/',
data: { 'pageNumber': pageNumber },
dataType: "json",
contentType: "application/json",
type: 'GET',
success: function (data) {
App.eventBus.publish('loadedNextEventsPage', data);
}
});
};
But neither has to pass in 2 parameters to the API. I'm guessing it's something really minor :/
Your action name is called "Authenticate", but you have included the following which will rename the action:
[ActionName("All")]
This makes the URL
/api/event/all
The problem lies in your url.
Apparently, ajax interpret / at the start of the url to be root
When the application is deployed on serverserver, its URL is something like http://localhost:8080/AppName/
with api/event/page/, ajax resolve the URL to http://localhost:8080/AppName/api/event/page/ or an url relative to your current directory.
However, with /api/event/page/, the URL is resolved to http://localhost:8080/api/event/page/
Hope it helped.
I have a simple $.ajax call that i did a million times before
$.ajax({
type: "POST",
url: url,
data: data,
sucess: function (data) {
alert(data);
}
});
and a controller that accepts my data without a problem but i can't seem to return data to the sucess function.
[HttpPost]
public ActionResult MyAction(MyClass data)
{
//do something
return Content("blabla");
}
What seems to be the problem?
EDIT:
Everything was ok but i wrote sucess instead of success.
$.ajax({
type: "POST",
url: url,
data: data,
success: function (data) {
alert(data);
}
});
It could be that you need to return a json-p style response... if the javascript and server side code are running on different domains then this is almost certainly the case.
Take a looks at http://api.jquery.com/jQuery.ajax/ for some more details.
I suggest you try :
$.ajax({
type: "POST",
datatype: "text",
async: false,
url: url,
data: data,
sucess: function (data) {
alert(data);
}
});
The idea is if you ask for a synchronous call and request type of text then it should get around the jsonp / callback issue.
Hopefully worth a try :)
I'm wiring the following method to my document.ready function. However, the "myAutoCompleteURL.aspx" URL is never being accessed (I have a breakpoint on the page, and it's never being hit).
Anybody know why this isn't working? I'm new to the UI version of AutoComplete; I had previously only used the jquery-based (deprecated) version.
function myAutoComplete(myTextBox, myLabel, myHidden) {
var myType = $(myLabel).html();
$(myTextBox).autocomplete({
source: function (request, response) {
$.ajax({
type: 'POST',
dataType: 'json',
url: "../myAutoCompleteURL.aspx",
data: { q: request.term, type: myType },
success: function (myData) {
response($.map(myData, function (myItem) {
return { label: myItem.name, value: myItem.name, id: myItem.id }
}));
}
});
},
select: function (event, ui) {
$(myTextBox).val(ui.myItem.name);
$(myHidden).val(ui.myItem.id);
return false;
}
});
}
You can remove the ../ in your url. I used to have the same issue sometime ago.
Secondly have an error function in your ajax call. If it hits the error function, then there is some problem in your data and you need to correct that.
As #GregL mentioned in his comment, that you are using JSON and not application/json :)
Use Firebug and look for what URL is being hit instead. If nothing shows up in the console, then the javascript code is not working at all.
There's got to be something I'm missing. I've tried using $.ajax() and $.post() to send a string to my ASP.NET MVC Controller, and while the Controller is being reached, the string is null when it gets there. So here is the post method I tried:
$.post("/Journal/SaveEntry", JSONstring);
And here is the ajax method I tried:
$.ajax({
url: "/Journal/SaveEntry",
type: "POST",
data: JSONstring
});
Here is my Controller:
public void SaveEntry(string data)
{
string somethingElse = data;
}
For background, I serialized a JSON object using JSON.stringify(), and this has been successful. I'm trying to send it to my Controller to Deserialize() it. But as I said, the string is arriving as null each time. Any ideas?
Thanks very much.
UPDATE: It was answered that my problem was that I was not using a key/value pair as a parameter to $.post(). So I tried this, but the string still arrived at the Controller as null:
$.post("/Journal/SaveEntry", { "jsonData": JSONstring });
Answered. I did not have the variable names set correctly after my first Update. I changed the variable name in the Controller to jsonData, so my new Controller header looks like:
public void SaveEntry(string jsonData)
and my post action in JS looks like:
$.post("/Journal/SaveEntry", { jsonData: JSONstring });
JSONstring is a "stringified" (or "serialized") JSON object that I serialized by using the JSON plugin offered at json.org. So:
JSONstring = JSON.stringify(journalEntry); // journalEntry is my JSON object
So the variable names in the $.post, and in the Controller method need to be the same name, or nothing will work. Good to know. Thanks for the answers.
Final Answer:
It seems that the variable names were not lining up in his post as i suggested in a comment after sorting out the data formatting issues (assuming that was also an issue.
Actually, make sure youre using the
right key name that your serverside
code is looking for as well as per
Olek's example - ie. if youre code is
looking for the variable data then you
need to use data as your key. –

#prodigitalson, that worked. The
variable names weren't lining up. Will
you post a second answer so I can
accept it? Thanks. – Mega Matt 6 hours

So he needed to use a key/value pair, and make sure he was grabbing the right variable from the request on the server side.
the data argument has to be key value pair
$.post("/Journal/SaveEntry", {"JSONString": JSONstring});
It seems dataType is missed. You may also set contentType just in case. Would you try this version?
$.ajax({
url: '/Journal/SaveEntry',
type: 'POST',
data: JSONstring,
dataType: 'json',
contentType: 'application/json; charset=utf-8'
});
Cheers.
Thanks for answer this solve my nightmare.
My grid
..
.Selectable()
.ClientEvents(events => events.OnRowSelected("onRowSelected"))
.Render();
<script type="text/javascript">
function onRowSelected(e) {
id = e.row.cells[0].innerHTML;
$.post("/<b>MyController</b>/GridSelectionCommand", { "id": id});
}
</script>
my controller
public ActionResult GridSelectionCommand(string id)
{
//Here i do what ever i need to do
}
The Way is here.
If you want specify
dataType: 'json'
Then use,
$('#ddlIssueType').change(function () {
var dataResponse = { itemTypeId: $('#ddlItemType').val(), transactionType: this.value };
$.ajax({
type: 'POST',
url: '#Url.Action("StoreLocationList", "../InventoryDailyTransaction")',
data: { 'itemTypeId': $('#ddlItemType').val(), 'transactionType': this.value },
dataType: 'json',
cache: false,
success: function (data) {
$('#ddlStoreLocation').get(0).options.length = 0;
$('#ddlStoreLocation').get(0).options[0] = new Option('--Select--', '');
$.map(data, function (item) {
$('#ddlStoreLocation').get(0).options[$('#ddlStoreLocation').get(0).options.length] = new Option(item.Display, item.Value);
});
},
error: function () {
alert("Connection Failed. Please Try Again");
}
});
If you do not specify
dataType: 'json'
Then use
$('#ddlItemType').change(function () {
$.ajax({
type: 'POST',
url: '#Url.Action("IssueTypeList", "SalesDept")',
data: { itemTypeId: this.value },
cache: false,
success: function (data) {
$('#ddlIssueType').get(0).options.length = 0;
$('#ddlIssueType').get(0).options[0] = new Option('--Select--', '');
$.map(data, function (item) {
$('#ddlIssueType').get(0).options[$('#ddlIssueType').get(0).options.length] = new Option(item.Display, item.Value);
});
},
error: function () {
alert("Connection Failed. Please Try Again");
}
});
If you want specify
dataType: 'json' and contentType: 'application/json; charset=utf-8'
Then Use
$.ajax({
type: 'POST',
url: '#Url.Action("LoadAvailableSerialForItem", "../InventoryDailyTransaction")',
data: "{'itemCode':'" + itemCode + "','storeLocation':'" + storeLocation + "'}",
contentType: "application/json; charset=utf-8",
dataType: 'json',
cache: false,
success: function (data) {
$('#ddlAvailAbleItemSerials').get(0).options.length = 0;
$('#ddlAvailAbleItemSerials').get(0).options[0] = new Option('--Select--', '');
$.map(data, function (item) {
$('#ddlAvailAbleItemSerials').get(0).options[$('#ddlAvailAbleItemSerials').get(0).options.length] = new Option(item.Display, item.Value);
});
},
error: function () {
alert("Connection Failed. Please Try Again.");
}
});
If you still can't get it to work, try checking the page URL you are calling the $.post from.
In my case I was calling this method from localhost:61965/Example and my code was:
$.post('Api/Example/New', { jsonData: jsonData });
Firefox sent this request to localhost:61965/Example/Api/Example/New, which is why my request didn't work.
