Shame :/ But thank you for that answer. I was fighting because I
thought that it is possible. Waste of time :/
So I have no choice and put all
$.get is asynchronous, meaning the call to $.get returns immediately, even
before the callback has happened. To answer your specific question, setting
a variable who's scope is outside the callback is as easy as defining the
variable outside the callback:
var foo;
$.get(..., function() { foo =

Erik - your
function isTracked(personcode, callback) {
$.get('trackstudent/istracked.php', {'personcode': personcode}, callback);
}
isTracked(code, function(tracked) {
// do something with tracked, exactly as you would have done above.
});
I thought that I understand that but Im doing something
First of all - Thank You very much - it is good lesson.

I tried that before:
function test()
after $.get work strange
function isTracked(personcode, callback) {
$.get('trackstudent/istracked.php', {'personcode': personcode},
callback);
}
isTracked(code, function(tracked) {
// do something with tracked, exactly as you would have
done above.
});

Ahh, I know know where was my mistake.
I tried something like that:
function a() {
var ret;

You're still expecting things to happen in the wrong order. It's *inside the

Yes, but I want have a function that will return what i get from
istracked.php
