Using closures in event listeners

This example creates a map with tappable markers displaying a secret message.

Read the documentation or view this example full screen.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: -25.363882, lng: 131.044922 }
  });

  var bounds = {
    north: -25.363882,
    south: -31.203405,
    east: 131.044922,
    west: 125.244141
  };

  // Display the area between the location southWest and northEast.
  map.fitBounds(bounds);

  // Add 5 markers to map at random locations.
  // For each of these markers, give them a title with their index, and when
  // they are clicked they should open an infowindow with text from a secret
  // message.
  var secretMessages = ['This', 'is', 'the', 'secret', 'message'];
  var lngSpan = bounds.east - bounds.west;
  var latSpan = bounds.north - bounds.south;
  for (var i = 0; i < secretMessages.length; ++i) {
    var marker = new google.maps.Marker({
      position: {
        lat: bounds.south + latSpan * Math.random(),
        lng: bounds.west + lngSpan * Math.random()
      },
      map: map
    });
    attachSecretMessage(marker, secretMessages[i]);
  }
}

// Attaches an info window to a marker with the provided message. When the
// marker is clicked, the info window will open with the secret message.

  });

  marker.addListener('click', function() {
    infowindow.open(marker.get('map'), marker);
  });
