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    lt  DOCTYPE html gt    lt html gt    lt head gt    lt meta name  viewport  content  initial-scale 1 0  user-scalable no   gt    lt meta http-equiv  content-type  content  text html  charset UTF-8   gt    lt title gt Reverse Geocoding lt  title gt     lt script type  text javascript  src  http   maps googleapis com maps api js sensor false  gt  lt  script gt    lt script type  text javascript  gt     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 lt results 0  address components length  i                  for  var b 0 b lt 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                        lt  script gt    lt  head gt    lt body onload  initialize    gt     lt  body gt    lt  html gt

As  PirateApp mentioned in his comment  it s explicitly against Google s Maps API Licensing to use the Maps API as you intend    You have a number of alternatives  including downloading a Geoip database and querying it locally or using a third party API service  such as my service ipdata co   ipdata gives you the geolocation  organisation  currency  timezone  calling code  flag and Tor Exit Node status data from any IPv4 or IPv6 address   And is scalable with 10 global endpoints each able to handle  10 000 requests per second      This answer uses a  test  API Key that is very limited and only meant for testing a few calls  Signup for your own Free API Key and get up to 1500 requests daily for development     x000D   x000D    get  https   api ipdata co api-key test   function response    x000D        ip   html  IP      response ip   x000D        city   html response city          response region   x000D        response   html JSON stringify response  null  4    x000D      jsonp    x000D   lt script src  https   ajax googleapis com ajax libs jquery 2 1 1 jquery min js  gt  lt  script gt  x000D   lt h1 gt  lt a href  https   ipdata co  gt ipdata co lt  a gt  - IP geolocation API lt  h1 gt  x000D   x000D   lt div id  ip  gt  lt  div gt  x000D   lt div id  city  gt  lt  div gt  x000D   lt pre id  response  gt  lt  pre gt  x000D   x000D   x000D    The fiddle  https   jsfiddle net ipdata 6wtf0q4g 922

Another approach to this is to use my service  http   ipinfo io  which returns the city  region and country name based on the user s current IP address  Here s a simple example     get  http   ipinfo io   function response        console log response city  response country       jsonp      Here s a more detailed JSFiddle example that also prints out the full response information  so you can see all of the available details  http   jsfiddle net zK5FN 2

After some searching and piecing together a couple of different solutions along with my own stuff  I came up with this function   function parse place place        var location            for  var ac   0  ac  lt  place address components length  ac                  var component   place address components ac            switch component types 0                         case  locality                   location  city     component long name                  break              case  administrative area level 1                   location  state     component long name                  break              case  country                   location  country     component long name                  break                        return location

You can use https   ip-api io  to get city Name  It supports IPv6   As a bonus it allows to check whether ip address is a tor node  public proxy or spammer    Javascript Code     document  ready function                  btnGetIpDetail   click function                  if      txtIP   val                            alert  IP address is reqired                    return false                              getJSON  http   ip-api io json         txtIP   val                     function  result                         alert  City Name      result city                       console log result                                              HTML Code   lt script src  https   code jquery com jquery-1 12 4 js  gt  lt  script gt   lt div gt       lt input type  text  id  txtIP    gt       lt button id  btnGetIpDetail  gt Get Location of IP lt  button gt   lt  div gt    JSON Output         ip    64 30 228 118        country code    US        country name    United States        region code    FL        region name    Florida        city    Fort Lauderdale        zip code    33309        time zone    America New York        latitude   26 1882       longitude   -80 1711       metro code   528       suspicious factors              is proxy   false           is tor node   false           is spam   false           is suspicious   false
