如何将ISO代码发送到支付处理器?

How can I send ISO codes to our payment processor? Right now the province field is a free text box. I would like to switch it to this fiddle: http://jsfiddle.net/RmvJ4/

Select Country:
 <select onchange="print_state('state',this.selectedIndex);" id="country" name = "country"></select> <br />
 City/District/State:
 <select name ="state" id = "state"></select>

print_country("country");
$('#country').val('Indonesia');
print_state('state',$('#country')[0].selectedIndex);

However my developer has told me that this will not send the ISO codes. I don't see where the ISO codes can be inserted.

The website that this will be used in can be found here:

This is what you need, just drop the flag data.
