  • You probably want to use the geocoder. See this fiddle for an example: http://jsfiddle.net/upsidown/5S3ce/ and watch the console for the results. If you have issues getting the information you want, open a new question with code that shows what you have tried. – MrUpsidown Feb 24 '16 at 11:45

If you have lat, and lng, you better got for calling Geocoder.geocode. Once you get OK in resonse, you can check address_componenets with type "administrative_area_level_n"

var latlng = new google.maps.LatLng(lat, lng);
        var geocoder = new google.maps.Geocoder();
        geocoder.geocode({ 'latLng': latlng }, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                if (results[1]) {
                    for (var i = 0; i < results[0].address_components.length; i++) {
                        for (var b = 0; b < results[0].address_components[i].types.length; b++) {
                            if (results[0].address_components[i].types[b] == "administrative_area_level_2") {
                                var city = results[0].address_components[i];
                            }
                        }
                    }
                }
            }

  • Please post complete and working code and explain what it does. – MrUpsidown Feb 24 '16 at 11:38
  • @MrUpsidown, looks self explanatory to me, but added as per your request (for the sake of completeness) – farhan iqbal Feb 29 '16 at 10:01

    It might be for you and others too. But many people here are beginner programmers and therefore posting complete code is always better. Thanks for updating your code. – MrUpsidown Feb 29 '16 at 10:09
