var map;
var maxZoomService;
var infoWindow;

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    zoom: 11,
    center: {lat: 35.6894, lng: 139.692},
    mapTypeId: 'hybrid'
  });

  infoWindow = new google.maps.InfoWindow();

  maxZoomService = new google.maps.MaxZoomService();

  map.addListener('click', showMaxZoom);
}

function showMaxZoom(e) {
  maxZoomService.getMaxZoomAtLatLng(e.latLng, function(response) {
    if (response.status !== 'OK') {
      infoWindow.setContent('Error in MaxZoomService');
    } else {
      infoWindow.setContent(
          'The maximum zoom at this location is: ' + response.zoom);
    }
