Javascript Question

Parsing address_components in Google Maps upon autocomplete select

I have the following code to parse the

country
when the autocomplete list is selected:

$('#spot_address').autocomplete({
// This bit uses the geocoder to fetch address values
source: function(request, response) {
geocoder.geocode( {'address': request.term }, function(results, status) {
// Get address_components
for (var i = 0; i < results[0].address_components.length; i++)
{
var addr = results[0].address_components[i];
var getCountry;
if (addr.types[0] == 'country')
getCountry = addr.long_name;
}
response($.map(results, function(item) {
return {
label: item.formatted_address,
value: item.formatted_address,
latitude: item.geometry.location.lat(),
longitude: item.geometry.location.lng(),
country: getCountry
}
}));
})
},

// This bit is executed upon selection of an address
select: function(event, ui) {
// Get values
$('#spot_country').val(ui.item.country);
$('#spot_lat').val(ui.item.latitude);
$('#spot_lng').val(ui.item.longitude);
var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
marker.setPosition(location);
map.setCenter(location);
},

// Changes the current marker when autocomplete dropdown list is focused
focus: function(event, ui) {
var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
marker.setPosition(location);
map.setCenter(location);
}
});


However, the code above doesn't work, and when the country is parsed, only the first result of the autocomplete is parsed no matter what, which is significant with the array
results[0]
because it only fetches the first result.

I tried to move it to the
select
function, but
ui
in
select
only contains
formatted_address
,
longitude
and
latitude
, but not the
address_components
.

What must I do to send the correct
country
when the autocomplete list item is selected?

Many thanks.

Here am I answering my own question again. Below is the full working code:

$('#spot_address').autocomplete({
  // This bit uses the geocoder to fetch address values
  source: function(request, response) {
    geocoder.geocode( {'address': request.term }, function(results, status) {
      response($.map(results, function(item) {
          // Get address_components
          for (var i = 0; i < item.address_components.length; i++)
          {
            var addr = item.address_components[i];
            var getCountry;
            if (addr.types[0] == 'country') 
              getCountry = addr.long_name;
          }
        return {
          label: item.formatted_address,
          value: item.formatted_address,
          latitude: item.geometry.location.lat(),
          longitude: item.geometry.location.lng(),
          country: getCountry
        }
      }));
    })
  },

  // This bit is executed upon selection of an address
  select: function(event, ui) {
    // Get values
    $('#spot_country').val(ui.item.country);
    $('#spot_lat').val(ui.item.latitude);
    $('#spot_lng').val(ui.item.longitude);
    var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
    marker.setPosition(location);
    map.setCenter(location);
  },

  // Changes the current marker when autocomplete dropdown list is focused
  focus: function(event, ui) {
    var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
    marker.setPosition(location);
    map.setCenter(location);
  }
});
