You can with ajax... depending on the result that is returned, you can
have your script perform various things. If the result returns with a
success for the call, you can call one thing, while if returns a
failure, you can, say alert the user with a message. Even single
threads allow for multiple routes. Every language has to wait for some
result or another before continuing along its path. You can't just
tell a program, for instance, to add 2 numbers, but continue with the
script before it finishes. That would make no sense. Maybe I
misunderstood your response, but that is what it sounds like you are
saying.
Also, jquery has actions for success and failure's of AJAX actions...
