Double Drop Down Forms - Created Country.html For Each Country With Some Presentation

I want do create a form ans a javascript function that does something like this:

But on submit to go to a link somethink like this:

I have created country.html for each country with some presentation, all in the main directory.

Then i have a directory for each country where there is a country_province.html for each province.

In conclusion after i select the 2 options from the form ,when i click submit to take me to: href="../country/country_province.html".
