Populate the longitude and latitude using google maps API

Question

I have the following html and javascript. The javascript populates location details from the google maps api to the html form fields. The idea is someone to enter their original

Answer 1

You don't have any code to populate the latitude and longitude fields. Add this to fillInAddress:

document.getElementById('latitude'+unique).value = place.geometry.location.lat();
document.getElementById('longitude'+unique).value = place.geometry.location.lng();

complete function:

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;
    }
  }
  document.getElementById('latitude'+unique).value = place.geometry.location.lat();
  document.getElementById('longitude'+unique).value = place.geometry.location.lng();
}

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;
    }
  }
  document.getElementById('latitude' + unique).value = place.geometry.location.lat();
  document.getElementById('longitude' + unique).value = place.geometry.location.lng();

}
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());
      });
    }
  }
