Modify the program as follows, this will look a bit simple to use v3
api standards.
directionsService.route(request, function(result, status) {
if (status == google.maps.DirectionsStatus.OK) {
path = result.routes[0].overview_path;
$(path).each(function(index, item) {
polyline.getPath().push(item);
bounds.extend(item);
})
polyline.setMap(map);
map.fitBounds(bounds);
}
});
