Dynamic Values for DropDowns

[ynaveen9]

I have a page with all form field to take input from user.
ex : when user selects a Country automatically all the states within that country should be populated in second list box with values(states) fetched from database.
and if I select state again all the cities under this state would appear in 3rd drop down.. like that...

I know Ajax will do this thing.. But can anyone point me to the sample code..

What platform are you working with? .NET, PHP, Other?

[ynaveen9]

am using Perl/CGI. Can you point to me some sample code for this purpose?

Thanks a bunch!

i think best to use ajax or java script as passing values to perl or cgi.

Thanks Fary4u for ur reply. Do you have some simple/sample code to show in for the same? I searched in web but all are confusing for a beginner like me.

[Fary4u]

give you idea to start with is.

<SCRIPT>
function checkLink(s) {
var val = escape(s)
var val = form1.dropdown.options[form1.dropdown.options.selectedIndex].value;
</script>

you can write like this.

document.getElementById("result").innerHTML = val;
