Activer Google Maps JavaScript API

Pour commencer, nous allons vous guider à travers la console Google Developers et effectuer deux ou trois petites choses :

  1. Créer ou sélectionner un projet
  2. Activer Google Maps JavaScript API et les services connexes
  3. Créer les clés appropriées

Polygon with Hole

This example creates a polygon with an inner hole, by defining an inner path wound in the opposite direction to the outer path. See the guide to polygons with holes. Note that you can also use the Data layer, which offers a simpler way of creating holes because it handles the order of the inner and outer paths for you.

You can also view this example full screen.

// This example creates a triangular polygon with a hole in it.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 5,
    center: {lat: 24.886, lng: -70.268},
  });

  // Define the LatLng coordinates for the polygon's  outer path.
  var outerCoords = [
    {lat: 25.774, lng: -80.190},
    {lat: 18.466, lng: -66.118},
    {lat: 32.321, lng: -64.757}
  ];

  // Define the LatLng coordinates for the polygon's inner path.
  // Note that the points forming the inner path are wound in the
  // opposite direction to those in the outer path, to form the hole.
  var innerCoords = [
    {lat: 28.745, lng: -70.579},
    {lat: 29.570, lng: -67.514},
    {lat: 27.339, lng: -66.668}
  ];

  // Construct the polygon, including both paths.
  var bermudaTriangle = new google.maps.Polygon({
    paths: [outerCoords, innerCoords],
    strokeColor: '#FFC107',
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: '#FFC107',
    fillOpacity: 0.35
  });
  bermudaTriangle.setMap(map);
}
