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:
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'];
}
});
};
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
What I've realized so far is that in most cases the ZIPCODE is always the last value inside each returned address, so, if you want to retrieve the very first zipcode (this is my case), you can use the following approach:
var address = results[0].address_components;
var zipcode = address[address.length - 1].long_name;
