title: Retrieving Postal Code with Google Maps Javascript API V3 Reverse Geocode
body: <p>I'm trying to submit a query using the postal code to my DB whenever the googlemaps viewport center changes. I know that this can be done with reverse geocoding with something like:</p>
  
  <pre><code>google.maps.event.addListener(map, 'center_changed', function(){
  newCenter();
  });
  ...
  function newCenter(){
  var newc = map.getCenter();
  geocoder.geocode({'latLng': newc}, function(results, status){
  if (status == google.maps.GeocoderStatus.OK) {
    var newzip = results[0].address_components['postal_code'];
    }
  });
  };
  </code></pre>
  
  <p>Of course, this code doesn't actually work. So I was wondering how I would need to change this in order to extract the postal code from the results array.
  Thanks</p>
