var infowindow, map, path = [], service = new google.maps.DirectionsService(), poly;


var directionDisplay;
var directionsService = new google.maps.DirectionsService();


function initialize() 
{
directionsDisplay = new google.maps.DirectionsRenderer();
 directionsDisplay.setPanel(document.getElementById("directionsPanel"));
var latlng = new google.maps.LatLng(41.850033, -87.6500523);
 var myOptions =

var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

directionsDisplay.setMap(map);


// FAZ A ROTA



google.maps.event.addListener(map, "click", function(evt) {

//Marcador

var image = 'http://i47.tinypic.com/11wg1o0.png'

    var marker2 = new google.maps.Marker({

});

var pointA = marker;
var pointB = marker2;

//var jsonObj = Maps.newDirectionFinder().setOrigin(pointA).setDestination(pointB).getDirections();



//  InfoBox
var content = '<iframe width="560" height="315"        src="http://www.youtube.com/embed/v2ORAUREQUo" frameborder="0" allowfullscreen></iframe> ';

infowindow = new google.maps.InfoWindow({
content: content    
});
google.maps.event.addListener(marker, 'click', function() 
{
      infowindow.open(map, this);
    });

    // rotas de bike
    var bikeLayer = new google.maps.BicyclingLayer();
    bikeLayer.setMap(map);  


  }

</script>
</head>
<body onload="initialize()">
  <div id="map_canvas" style="width:100%; height:100%"></div>
</body>

</html>

This is the part that's do the rote

google.maps.event.addListener(map, "click", function(evt) {
if (path.length == 0) {
  path.push(evt.latLng);
  poly = new google.maps.Polyline ({ map: map});
  poly.setPath(path);
} else {
  service.route({
    origin: path[path.length - 1],
    destination: evt.latLng,
    travelMode: google.maps.DirectionsTravelMode.DRIVING  //Pode ser Walking, Driving ou Bicycling

  }, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      path = path.concat(result.routes[0].overview_path);
      poly.setPath(path);
       }
     });
    }
  });

To finish, thats my try of put collor

var polylineOptions = {
   strokeColor:"#FF0000",
   strokeOpacity: 1, 
   strokeWeight: 2, 
   zIndex: 5
}
google.maps.event.addListener(map, "click", function(evt) {
  if (path.length == 0) {
  path.push(evt.latLng);
  poly = new google.maps.Polyline (polylineOptions)({map: map});
  poly.setPath(path);
 } else {
  service.route({
    origin: path[path.length - 1],
    destination: evt.latLng,
    travelMode: google.maps.DirectionsTravelMode.DRIVING  //Pode ser Walking, Driving ou Bicycling

  },  function(result, status) {
      if (status == google.maps.DirectionsStatus.OK) {
      path = path.concat(result.routes[0].overview_path);
      poly.setPath(path);
     }
    });
   }
 });

Whats the error ?

Solution

This doesn't look like the right syntax to me:

poly = new google.maps.Polyline (polylineOptions)({map: map});

Instead I'd say either add the map attribute to your polylineOptions, or call the setMap function on the poly object.
