Google Maps API autocomplete 2nd address fields on same page

I am using the Google Maps API on my page, the page asks the user to fill out your "Current Address" and the "New Address".

I can get the autocomplete to work on the 1st address but it does not work for the second address, I have done lots of research and looked at simular posts on stackoverflow but I cannot find anyone who has had the same problem.

Here is my code;

<div id="locationField">
<input id="autocomplete" placeholder="Start typing your address" onFocus="geolocate()" type="text"></input>
</div>

<div id="addressone">
<input type="text" id="street_number" name="street_number"></input>
<input type="text" id="route" name="street_name"></input>
<input type="text" id="locality" name="town_city"></input>
<input type="text" id="postal_code" name="postcode"></input>
<input type="text" id="country" name="country"></input>
</div>

<div id="locationField2">
<input id="autocomplete2" placeholder="Start typing your address" onFocus="geolocate()" type="text"></input>
</div>

<div id="addresstwo">
<input type="text" id="street_number2" name="street_number2"></input>
<input type="text" id="route2" name="street_name2"></input>
<input type="text" id="locality2" name="town_city2"></input>
<input type="text" id="postal_code2" name="postcode2"></input>
<input type="text" id="country2" name="country2"></input>
</div>
<script>

// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.

var placeSearch, autocomplete;
var componentForm = {
street_number: 'short_name',
route: 'long_name',
locality: 'long_name',
administrative_area_level_1: 'short_name',
country: 'long_name',
postal_code: 'short_name'
};

function initAutocomplete() {
// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
{types: ['geocode']});

// When the user selects an address from the dropdown, populate the address
// fields in the form.
autocomplete.addListener('place_changed', fillInAddress);

}

// [START region_fillform]
function fillInAddress() {
// Get the place details from the autocomplete object.
var place = autocomplete.getPlace();

for (var component in componentForm) {
document.getElementById(component).value = '';
document.getElementById(component).disabled = false;
}

// Get each component of the address from the place details
// and fill the corresponding field on the form.
for (var i = 0; i < place.address_components.length; i++) {
var addressType = place.address_components[i].types[0];
if (componentForm[addressType]) {
var val = place.address_components[i][componentForm[addressType]];
document.getElementById(addressType).value = val;
}
}
}
// [END region_fillform]

// [START region_geolocation]
// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var geolocation = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
var circle = new google.maps.Circle({
center: geolocation,
radius: position.coords.accuracy
});
autocomplete.setBounds(circle.getBounds());
});
}
}
// [END region_geolocation]

</script>

Answer

You need to hande the two autocomplete inputs. Here is a generalized version of fillInAddress that will handle multiple autocomplete objects with fields with a unique extension (the "2" in your second version of the form):

function fillInAddress(autocomplete, unique) {
    // Get the place details from the autocomplete object.
    var place = autocomplete.getPlace();

    for (var component in componentForm) {
        if(!!document.getElementById(component + unique)){
            document.getElementById(component + unique).value = '';
            document.getElementById(component + unique).disabled = false;
        }
    }

    // Get each component of the address from the place details
    // and fill the corresponding field on the form.
    for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType] && document.getElementById(addressType + unique)) {
            var val = place.address_components[i][componentForm[addressType]];
            document.getElementById(addressType + unique).value = val;
        }
    }
}

Call it like this:

// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('autocomplete')), {
    types: ['geocode']
});

// When the user selects an address from the dropdown, populate the address
// fields in the form.
autocomplete.addListener('place_changed', function () {
    fillInAddress(autocomplete, "");
});

// Create the second autocomplete object, restricting the search to geographical
// location types.
autocomplete2 = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('autocomplete2')), {
    types: ['geocode']
});
autocomplete2.addListener('place_changed', function () {
    fillInAddress(autocomplete2, "2");
});

working code snippet:

// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.

var placeSearch, autocomplete, autocomplete2;
var componentForm = {
  street_number: 'short_name',
  route: 'long_name',
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  country: 'long_name',
  postal_code: 'short_name'
};

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement} */
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  autocomplete.addListener('place_changed', function() {
    fillInAddress(autocomplete, "");
  });

  autocomplete2 = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement} */
    (document.getElementById('autocomplete2')), {
      types: ['geocode']
    });
  autocomplete2.addListener('place_changed', function() {
    fillInAddress(autocomplete2, "2");
  });

}

function fillInAddress(autocomplete, unique) {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    if (!!document.getElementById(component + unique)) {
      document.getElementById(component + unique).value = '';
      document.getElementById(component + unique).disabled = false;
    }
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType] && document.getElementById(addressType + unique)) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType + unique).value = val;
    }
  }
}
google.maps.event.addDomListener(window, "load", initAutocomplete);

function geolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
