Interrogating Google Geocoding results
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. |
