Linking two HTML SELECT''s together
Hi,
How do I link two HTML SELECT''s together. Let''s say for example that I
have a drop-down list with a list of all countries. Once the user
selects one of the countries I would like to make an AJAX call back to
the server to populate the second drop-down list with all of the cities
for that country.
Any ideas on how to go about to do this?
Regards
Jerrie Pelser
