Draggable directions

This example demonstrates the use of the DirectionsService object to fetch directions between draggable markers.

Read the documentation or view this example full screen.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: -24.345, lng: 134.46}  // Australia.
  });

  var directionsService = new google.maps.DirectionsService;
  var directionsDisplay = new google.maps.DirectionsRenderer({
    draggable: true,
    map: map,
    panel: document.getElementById('right-panel')
  });

  directionsDisplay.addListener('directions_changed', function() {
    computeTotalDistance(directionsDisplay.getDirections());
  });

  displayRoute('Perth, WA', 'Sydney, NSW', directionsService,
      directionsDisplay);
}

function displayRoute(origin, destination, service, display) {
  service.route({
    origin: origin,
    destination: destination,
    waypoints: [{location: 'Adelaide, SA'}, {location: 'Broken Hill, NSW'}],
    travelMode: 'DRIVING',
    avoidTolls: true
  }, function(response, status) {
