javascript - How can I get the country and region code using geolocation instead of full country and region names -

i'm building website uses geolocation in html5 provide service specific region in user is. here have been doing: use javascript in so question country , administrative region names. search country , region names in database , returns location-specific data can display.

here script:

<script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script> <script>     var region = "";     var country = "";     function getlocation()     {         if (navigator.geolocation)           {               navigator.geolocation.getcurrentposition(showposition,nogeolocation);           } else {               ...           }     }     function showposition(position)     {         var geocoder = new google.maps.geocoder();         var latlong = new google.maps.latlng(position.coords.latitude,position.coords.longitude);         geocoder.geocode({'latlng': latlong}, function(results, status) {               if (status == google.maps.geocoderstatus.ok) {                   if (results[0]) {                     (var = 0; < results[0].address_components.length; i++)                     {                         var longname = results[0].address_components[i].long_name;                         var type = results[0].address_components[i].types;                         if (type.indexof("administrative_area_level_1") != -1)                         {                             region = longname;                         }                         if (type.indexof("country") != -1)                         {                             country = longname;                         }                       }               }         });     }     function nogeolocation()     {         ...     }      getlocation(); </script> 

this script working fine. had no problem it, until used os , browser set different languages. script returned country , region names in language. of course, couldnt find match in database.

so, question(s) (are): there way language-independent country , region codes google reverse geolocation? or there way in english? better off using ip geolocation then? or should use totally different method?

thanks help.

you should use short_name value country, two-digit country code. these iso standard codes , should basis database lookup, not localized country name.
