どのように新しいマーカーを追加し、新しいルートを計算します

ダミアンRicobelli：

私は一連のウェイポイントが含まれているルートとマップを持っています。私は、地図上をクリックして、新しいマーカーを追加できるようにしたい、と自動的に考慮にoptimizeWaypointsの設定取り、以前と新しいマーカーでルートを計算する：真を。

私が試したが、私はそれを行う方法を理解していません。

誰もがこれを行う方法を知っていますか？

     function initMap() {
        var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 4,
          center: {lat: -32.949798, lng: -60.681911}

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

        directionsRenderer.addListener('directions_changed', function() {
          computeTotalDistance(directionsRenderer.getDirections());
        });
       
       google.maps.event.addListener(map, 'click', function(event) {
           placeMarker(event.latLng);
       });

        function placeMarker(location) {
            var marker = new google.maps.Marker({

あなたは地図をクリックすると、「追加ウェイポイント」の配列にクリックした場所を追加します。

var addedWaypoints = [];

function addWaypoint(latLng) {
  addedWaypoints.push(latLng);
}

リクエストに新しいウェイポイントを追加し、再び方向サービスを呼び出します。

google.maps.event.addListener(map, 'click', function(event) {
  addWaypoint(event.latLng);
  displayRoute(start, end, directionsService, directionsRenderer);
});

function displayRoute(origin, destination, service, display) {
  var waypoints = [
    {location: new google.maps.LatLng(-32.930572, -60.662137)},
    {location: new google.maps.LatLng(-32.923554, -60.665930)},
    {location: new google.maps.LatLng(-32.936270, -60.652841)}
  ];
  for (var i=0; i<addedWaypoints.length;i++) {
    waypoints.push({
      location: addedWaypoints[i]
    });
  }
  service.route({
    origin: origin,
    destination: destination,
    waypoints: waypoints,
