Deriving worth from a JSON object

My JSON data structure has the following format:

  ....
        "location" : {
           "lat" : 37.42140090,
           "lng" : -122.08537010
        },
  ....

I am having trouble accessing the lat and lng values. Any suggestions on how to do this?

Currently, my code is as follows:

     results[0].geometry.location.lat
  or results[0].geometry.location.lng

Unfortunately, this code does not seem to work. Oddly enough, I get the output when only using results[0].geometry.location.

The specific JSON dataset I am working with can be found here: http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true

Update --

This is the method I am utilizing to send a request to the API

           geocoder.geocode( { 'address': search_addr}, function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                var t = results[0].geometry.location.lat;
            } else {
              alert('Geocode was not successful for the following reason: ' + status);
            }

Thank you

I tested out the code provided:

alert(json.results[0].geometry.location.lat);

and it successfully executed, as demonstrated in this fiddle:

When utilizing Google's JavaScript APIs, you typically work with wrapper Objects instead of directly interacting with the parsed JSON.

In particular, accessing results[0].geometry.location will provide an instance of google.maps.LatLng. Therefore, instead of storing the values themselves, lat and lng are methods that will retrieve the values:

var geoLoc = results[0].geometry.location;
var lat = geoLoc.lat();
var lng = geoLoc.lng();
