Re-read my earlier answer, and it should be clear that it doesn't make
sense. If it isn't then you need to look into how HTTP and the Web in
general works, the request-response things and so on. Traditionally
user interaction is handled by re-loading the whole web page when the
user clicks on something. Nowadays you can contact the server with
AJAX instead and change only parts of the page (like with JQuery), but
the request-response/client-server modell applies to that too.
