onclick event - post and execute function?

[11oclocktuesday]

I have a page that I want to collect some simple data to send to a MySQL database, and execute a javascript function on the page. At the moment it works - but only with 2 buttons - one button's onclick event starts the function, and the other button 'posts' the data. Does anyone know what code will start a function and post data to the MySQL server in the one hit?

You can use an Ajax-like setup. Where on the click you first send the data via JS to the server, let it update the database and upon successful return continue with another JS function.
