Reverse Geocoding by Place ID

This example uses reverse geocoding to retrieve an address for a given place ID.

  var infowindow = new google.maps.InfoWindow;

  document.getElementById('submit').addEventListener('click', function() {
    geocodePlaceId(geocoder, map, infowindow);
  });

// This function is called when the user clicks the UI button requesting
// a reverse geocode.
