jQuery ajax in ajax request

We have some code(simplified) that looks like bellow. We run function x which does an ajax call. When the call is done we call a different function recalculateOrderObjects which also does an ajax call. When this one is completed, it should output the data that which is obtained via the second call. However, what actually happens is that only the first ajax call is made and the second is not executed (or at least immediately goes to done) but does show the data obtained from the first call as the data obtained from the second one.
When running only the recalculateOrderObjects function the function does work as expected.
Edit 1
The subscription variable is a global
There are no errors on the console
Also, when I first call recalculateOrderObjects independent the function work when first x is called and after that I call recalculateOrderObjects independently the function will not work and shows the same behaviour as when called from `x.'
Edit 2
I tried the suggestion to use successinstead of doneas well. With the same result. recalucateOrderObjects is called succesfully, thought after one executing x the whole ajax call in recalucateOrderObjects is never requested again but instead thinks that it is succesfully executed.
function recalculateOrderObjects() {
$.ajax({
type: 'post',
url: url + "something",
data: {data: subscription}
})
.done(function (data) {
console.log('Data ' + data);
});
}
function x(){
jQuery.ajax({
type: "get",
dataType: "json",
url: url,
async: false
}).done(function (response) {
recalculateOrderObjects();
}
});}
x();

You can't get success responce by ".done" function.
"success" function gives you responce after ajax load.
Please try below code
function recalculateOrderObjects() {
$.ajax({
type: 'post',
url: url + "something",
data: {data: subscription},
success: function(data) {
console.log('Data ' + data);
}
});
}
function x(){
jQuery.ajax({
type: "get",
dataType: "json",
url: url,
success: function(data) {
recalculateOrderObjects();
}
});
}
x();
OR
function x(){
jQuery.ajax({
type: "get",
dataType: "json",
url: url,
success: function(data) {
$.ajax({
type: 'post',
url: url + "something",
data: {data: subscription},
success: function(data) {
console.log('Data ' + data);
}
});
}
});
}
x();

Why can't I do .ajax ( return data; )? jQuery

I'm trying to get my function to return the data it got into another function but it doesn't seem to work? How can I get it to return the data?
function playerid(playername) {
$.ajax({
type: "POST",
url: "fn.php?playerid",
data: "playername="+playername,
success: function(data) {
//$("#test").text(data);
return data;
}
});
}
I want to use it in another function like this
showBids(playerid(ui.item.value));
function showBids(playerid) {
$.ajax({
type: "POST",
url: "poll.php?",
async: true,
dataType: 'json',
timeout: 50000,
data: "playerid="+playerid,
success: function(data) {
//.each(data, function(k ,v) {
//})
//$("#current_high").append(data);
setTimeout("getData()", 1000);
}
});

First of all, your playerid() does not return anything, so what do you want to use? It has only $.ajax() call in it, no return statement (one of the callbacks in $.ajax() has return statement, but see below).
Secondly, JavaScript does some things asynchonously, otherwise every interface element would need to wait to react to user action until the AJAX call returns from the server.
Use event-based approach, by passing callbacks to some functions. Then, after they finish, just call the callbacks passing them the result:
function getplayerid(playername, callback) {
$.ajax({
type: "POST",
url: "fn.php?playerid",
data: "playername="+playername,
success: function(data) {
//$("#test").text(data);
callback(data);
}
});
}
and then use it like that:
getplayerid(ui.item.value, showBids);
(notice function name change since it does not actually return player ID, it gets it and passes it to callback)

You could try to use syncronous Ajax:
function playerid(playername) {
return $.ajax({
type: "POST",
url: "fn.php?playerid",
data: "playername="+playername,
async : false //making Ajax syncronous
}).responseText;
}
Otherwise you need to use showBids function as callback:
function playerid(playername, callback) {
$.ajax({
type: "POST",
url: "fn.php?playerid",
data: "playername="+playername,
success: function(data) {
callback(data);
}
});
}
//Usage
playerid(ui.item.value,showBids);

"undefined" for alerting an ajax call response , why?

i am trying to alert the return value captured by the ajax request. The web method it is refering is returning a boolean value of true or false, and when i am trying to access it outside the ajax method it gives a message "undefined" :?
<script type="text/javascript" language="javascript">
$(document).ready(function () {
var authInfo;
$.ajax({
type: "POST",
url: "service.asmx/getAuthInfo",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
authInfo = msg.d;
},
});
alert(authInfo);
});
</script>
why is the alert(authInfo) giving me as "undefined" ?? Please help !
where does this piece of code fit on the above context ?
if(auhthInfo){
$(".ansitem").editable('FetchUpdate.aspx', {
style: 'background-color:inherit;',
type: 'textarea',
indicator: '<img src="spinner.gif">',
event: 'dblclick',
onblur: 'submit',
submitdata: function (value, settings) {
return { orgval: value};
},
});
};

Your "$.ajax()" call is asynchronous, and thus the results are not available until the response is returned from the server.
If you put your "alert()" inside the "success" callback, it should work (if the HTTP transaction works).

EDITED TO HANDLE YOUR NEW CODE:
<script type="text/javascript" language="javascript">
$(document).ready(function () {
var authInfo;
$.ajax({
type: "POST",
url: "service.asmx/getAuthInfo",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
// alert(msg.d); // here it will work as it is only called when it succeeds.
MyHanlder(msg);
},
});
// alert(authInfo); // here authinfo has no value as the AJAX call may not have returned.
});
function MyHandler(msg) {
if(msg.d){
$(".ansitem").editable('FetchUpdate.aspx', {
style: 'background-color:inherit;',
type: 'textarea',
indicator: '<img src="spinner.gif">',
event: 'dblclick',
onblur: 'submit',
submitdata: function (value, settings) { return { orgval: value}; },
});
};
}
</script>

The request and the response that you get via ajax calls are asynchronous. I think it is not possible to alert the value that you get in response at the end of ready function because you are not assured that you will be getting your response before the function completes execution.

You are alerting the authInfo variable before the actual ajax call have returned. If you try this:
success:function(msg) {
authInfo = msg.d;
alert(authInfo);
}
I think you will get the correct result.

Because the AJAX call is done asynchronously, the alert does not have the value at the time of execution. If you place the alert inside the success function you should see the appropriate results. I also noticed you have an extra comma in the $.ajax parameters after the success function parameter.

It appears:
alert(authInfo);
Is running immediately when your document is ready.
However, the variable is not being initialized until after the AJAX call completes.
Try moving the alert to:
$.ajax({
type: "POST",
url: "service.asmx/getAuthInfo",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
authInfo = msg.d;
alert(authInfo);
},
});
If you need to do anything more complex with the value, you can try re-factoring the code into another function:
function onSuccess(msg)
{
if(msg.d)
{
window.alert('The value is true!');
}
else
{
window.alert('The value is false!')
}
}
$.ajax({
type: "POST",
url: "service.asmx/getAuthInfo",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: onSuccess,
});

Call another method onSuccess event of an Ajax call

I have an AJAX call on MVC3 it looks like this
save: function () {
$.ajax({
url: "#Url.Action("Save")",
type:"post",
data: ko.toJSON(this),
contentType:"application/json",
success: function(result){alert(result.message)}
});
}
The trouble is the line
success: function(result){alert(result.message)}
I want to pass all the messing things in a HtmlHelper, however, the success line prevents me from doing so, is there a way I can specify a function for that line
success: doSomeStuff(result)
and
function doSomeStuff(result){alert(result.message)}
Thanks in advance

Simply pass the function name to the success: method and it will pass the data onwards, as such:
save: function () {
$.ajax({
url: "#Url.Action("Save")",
type:"post",
data: ko.toJSON(this),
contentType:"application/json",
success: doSomeStuff
});
}

Why do I have to enclose a function in another function?

When I write a function in JSON, why do I have to enclose it inside an anonymous function?
This works:
$.ajax({
type: 'POST',
url: 'http://www.myurl.com',
data: data,
success: function(data) {
alert(data);
}
});
This doesn't work:
$.ajax({
type: 'POST',
url: 'http://www.myurl.com',
data: data,
success: alert(data)
});
Thanks

You can do that. You just using the wrong syntax.
The success property needs a function expression not a function() call (which then returns a value into success);
So
success: myfunction
instead of
success: myfunction()

In short, because you're executing alert() and trying to assign the result to the success callback, so this won't work (the result of alert() is undefined). However you can do this:
$.ajax({
type: 'POST',
url: 'http://www.myurl.com',
data: data,
success: customFunc //*not* customFunc() which would call it
});
In this case customFunc will receive the same parameters as success passes, so it's signature should be: customFunc(data, textStatus, XMLHttpRequest), though it can be a subset, for example customFunc(data).
