How to control action?


I have an HTML form with a dropdown for country list. I want to display individual ASP pages on selecting different countries. But at the same time I want the form the submit the values already filled to the next ASP page that appears. How do I control the form’s action property to send the user to a different page AND submit the values on selecting any country? I feel it is with javascript but I am unable to figure out how. Please help!
