The problem is not the scope. $.ajax is asynchronous and therefore the
methods returns, calls the alters and then some (undefined) time later
the success callback is executed. While it is possible to use $.ajax for
synchronous calls, I (and I guess everyone else on this list) recommend
to work with the callbacks, putting your altert inside the success
callback or calling another function from there.
