jQuery: Passing variables to function upon successful $.get request

Question

Is it possible to pass predefined variables to functions called upon successful jQuery $.get request?

As in the example below the PHP script would return "bar":

var extra = "foo";
$.get(baar.php, function(data, extra){
    alert(extra + data);
});

Thus my goal being an alert box proclaiming "foobar" to the world.

Thanks.

You don't need to pass it, extra will be available inside the callback because of how JavaScript scoping works. So:

var extra = "foo";
$.get('baar.php', function(data){
    alert(extra + data);
});
