hey U guys..
I need a jsp code which uses AJAX with dropdowns..
Something like COUNTRY NAME in one dropdown and STATE NAME in the other...
You may select any STATE at first.. Later when we CHANGE the COUNTRY NAME, states of that particular COUNTRY WILL GET REFRESHED IN THE STATE DROPDOWN...
So any text before or after the AJAX section will not be refreshed...
and no php or .net please
Thank you
