按照您要获取路线的顺序放置locations数组。

var locations = [
    ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
    ['Bondi Beach', -33.890542, 151.274856, 4],
    ['Coogee Beach', -33.923036, 151.259052, 5],
    ['Maroubra Beach', -33.950198, 151.259302, 1],
    ['Cronulla Beach', -34.028249, 151.157507, 3]
  ];

使用origin中的第一个标记创建DirectionsService的请求，destination中的最后一个标记，将其余标记推送到路标点数组：

if (i == 0) request.origin = marker.getPosition();
else if (i == locations.length - 1) request.destination = marker.getPosition();
else {
  if (!request.waypoints) request.waypoints = [];
  request.waypoints.push({
    location: marker.getPosition(),
    stopover: true
  });
}

致电指示服务。

directionsService.route(request, function(result, status) {
  if (status == google.maps.DirectionsStatus.OK) {
    directionsDisplay.setDirections(result);
  }
});
