Lat/Lng Object Literal

This example demonstrates using a LatLng object literal instead of a google.maps.LatLng object, to center the map and add a marker. LatLng object literals are a convenient way to add a LatLng coordinate and, in most cases, can be used in place of a google.maps.LatLng object.

// In this example, we center the map, and add a marker, using a LatLng object
// literal instead of a google.maps.LatLng object. LatLng object literals are
// a convenient way to add a LatLng coordinate and, in most cases, can be used
// in place of a google.maps.LatLng object.

let map: google.maps.Map;

function initMap(): void {
  const mapOptions = {
    zoom: 8,
    center: { lat: -34.397, lng: 150.644 }
  };
  map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    mapOptions
  );

  const marker = new google.maps.Marker({
    // The below line is equivalent to writing:
    // position: new google.maps.LatLng(-34.397, 150.644)
    position: { lat: -34.397, lng: 150.644 },
    map: map
  });

  // You can use a LatLng literal in place of a google.maps.LatLng object when
  // creating the Marker object. Once the Marker object is instantiated, its
  // position will be available as a google.maps.LatLng object. In this case,
  // we retrieve the marker's position using the
  // google.maps.LatLng.getPosition() method.
  const infowindow = new google.maps.InfoWindow({
    content: "<p>Marker Location:" + marker.getPosition() + "</p>"
  });

  google.maps.event.addListener(marker, "click", () => {
    infowindow.open(map, marker);
  });
}
