Try using this instead   var latitude   results 0  geometry location lat    var longitude   results 0  geometry location lng      It s bit hard to navigate Google s api but here is the relevant documentation   One thing I had trouble finding was how to go in the other direction  From coordinates to an address  Here is the code I neded upp using  Please not that I also use jquery     each results 0  address components  function            CreateDialog   find  input name     this types       attr  value   this long name         What I m doing is to loop through all the returned address components and test if their types match any input element names I have in a form  And if they do I set the value of the element to the address components value  If you re only interrested in the whole formated address then you can follow Google s example

The script tag to the api has changed recently   Use something like this to query the Geocoding API and get the JSON object back    lt script type  text javascript  src  https   maps googleapis com maps api geocode json address THE ADDRESS YOU WANT TO GEOCODE amp key YOUR API KEY  gt  lt  script gt    The address could be something like      1600 Amphitheatre Parkway  Mountain View  CA  URI Encoded  you should Google it  Very useful    or simply      1600 Amphitheatre Parkway  Mountain View  CA   By entering this address https   maps googleapis com maps api geocode json address 1600 Amphitheatre Parkway  Mountain View  CA amp key YOUR API KEY inside the browser  along with my API Key  I get back a JSON object which contains the Latitude  amp  Longitude for the city of Moutain view  CA     results                address components                            long name     1600               short name     1600               types       street number                                     long name     Amphitheatre Parkway               short name     Amphitheatre Pkwy               types       route                                     long name     Mountain View               short name     Mountain View               types       locality    political                                     long name     Santa Clara County               short name     Santa Clara County               types       administrative area level 2    political                                     long name     California               short name     CA               types       administrative area level 1    political                                     long name     United States               short name     US               types       country    political                                     long name     94043               short name     94043               types       postal code                            formatted address     1600 Amphitheatre Pkwy  Mountain View  CA 94043  USA         geometry               location                  lat    37 4222556              lng    -122 0838589                     location type     ROOFTOP            viewport                  northeast                     lat    37 4236045802915                 lng    -122 0825099197085                           southwest                     lat    37 4209066197085                 lng    -122 0852078802915                                      place id     ChIJ2eUgeAK6j4ARbn5u wAGqWA         types       street address          status     OK     Web Frameworks such like AngularJS allow us to perform these queries with ease

You re accessing the latitude and longitude incorrectly   Try   lt script type  text javascript  src  http   maps google com maps api js sensor false  gt  lt  script gt   lt script type  text javascript  gt   var geocoder   new google maps Geocoder    var address    new york    geocoder geocode     address   address   function results  status       if  status    google maps GeocoderStatus OK        var latitude   results 0  geometry location lat        var longitude   results 0  geometry location lng        alert latitude              lt  script gt
