Question

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.

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);
  }
});
