Interrogating Google Geocoding results

BlastFirst · 02-12-2013, 05:19 PM

I've not worked with JSON and am a Javascript novice too and I'm confused with the results I get from the Geocoder API. I am interested in finding latitude and longitude and need to extract these as individual numbers for later processing - I get the lat and long in a format (xxxx, xxxx) but don't seem to be able to do anything more with it.

To get the above lat and long format I just use:

Code:

function codeAddress() {
geocoder = new google.maps.Geocoder();
       var address = document.getElementById('address').value;
       geocoder.geocode( { 'address': address}, function(results, status) {
          if (status == google.maps.GeocoderStatus.OK) {
		var latLon=results[0].geometry.location;
		alert(results[0].geometry.location);
	  } else {
                alert('Geocode was not successful for the following reason: ' + status);
          }
       });

I would have thought to get individual lat and long I could use:

Code:

var lat=results[0].geometry.location.lat;
var lon=results[0].geometry.location.lng;

Or even manipulate latLon as a string - seems not.

The Geocoding result format is at :

https://developers.google.com/maps/d...ion/geocoding/

Code:

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Pkwy",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Santa Clara",
               "short_name" : "Santa Clara",
               "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" : 37.42291810,
               "lng" : -122.08542120
            },
            "location_type" : "ROOFTOP",
            "viewport" : {
               "northeast" : {
                  "lat" : 37.42426708029149,
                  "lng" : -122.0840722197085
               },
               "southwest" : {
                  "lat" : 37.42156911970850,
                  "lng" : -122.0867701802915
               }
            }
         },
         "types" : [ "street_address" ]
      }
   ],
   "status" : "OK"
}

Any assistance appreciated.

I found it, for reference in case anyone stumbles across this post I used:

Code:

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