Get city name using geolocation

You would do something like that using Google API.

Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.

"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.

Anyhow - more details on google response types can be found here and here.

Below is the code that should do the trick:

<!DOCTYPE html> 
<html> 
<head> 
<meta name="viewport" content="initial-scale=1.0, user-scalable=no"/> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script> 
<script type="text/javascript"> 
  var geocoder;

  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(successFunction, errorFunction);
} 
//Get the latitude and the longitude;
function successFunction(position) {
    var lat = position.coords.latitude;
    var lng = position.coords.longitude;
    codeLatLng(lat, lng)
}

function errorFunction(){
    alert("Geocoder failed");
}

  function initialize() {
    geocoder = new google.maps.Geocoder();



  }

  function codeLatLng(lat, lng) {

    var latlng = new google.maps.LatLng(lat, lng);
    geocoder.geocode({'latLng': latlng}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
      console.log(results)
        if (results[1]) {
         //formatted address
         alert(results[0].formatted_address)
        //find country name
             for (var i=0; i<results[0].address_components.length; i++) {
            for (var b=0;b<results[0].address_components[i].types.length;b++) {

            //there are different types that might hold a city admin_area_lvl_1 usually does in come cases looking for sublocality type will be more appropriate
                if (results[0].address_components[i].types[b] == "administrative_area_level_1") {
                    //this is the object you are looking for
                    city= results[0].address_components[i];
                    break;
                }
            }
        }
        //city data
        alert(city.short_name + " " + city.long_name)


        } else {
          alert("No results found");
        }
      } else {
        alert("Geocoder failed due to: " + status);
      }
    });
  }
</script> 
</head> 
<body onload="initialize()"> 

</body> 
</html>

$.ajax({
  url: "https://geolocation-db.com/jsonp",
  jsonpCallback: "callback",
  dataType: "jsonp",
  success: function(location) {
    $('#country').html(location.country_name);
    $('#state').html(location.state);
    $('#city').html(location.city);
    $('#latitude').html(location.latitude);
    $('#longitude').html(location.longitude);
    $('#ip').html(location.IPv4);
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

<div>Country: <span id="country"></span></div>
  <div>State: <span id="state"></span></div>
    <div>City: <span id="city"></span></div>
      <div>Latitude: <span id="latitude"></span></div>
        <div>Longitude: <span id="longitude"></span></div>
          <div>IP: <span id="ip"></span></div>

Using html5 geolocation requires user permission. In case you don't want this, go for an external locator like https://geolocation-db.com IPv6 is supported. No restrictions and unlimited requests allowed.

JSON: https://geolocation-db.com/json
JSONP: https://geolocation-db.com/jsonp
