title: How do I get just the postal code from a reverse geocode result?
body: <p>I've looked all over the internet for a simple answer to this, but I can't seem to find one anywhere. I do a simple reverse geocode of a latitude and longitude and I am returned the huge results object. Where do I go from there? Here is what I have so far. Currently zipcode returns "undefined".</p>
  
  <pre><code>geocoder.geocode( {'latLng' : event.latLng}, function(results, status) {
      for(var i; i &lt; results.length; i++){
          for(var j=0;j &lt; results[i].address_components.length; j++){
              for(var k=0; k &lt; results[i].address_components[j].types.length; k++){
                  if(results[i].address_components[j].types[k] == "postal_code"){
                      var zipcode = results[i].address_components[j].short_name;
                  }
              }
          }
      }
  });
  </code></pre>
