Google map driving direction source code for their example?
Google gave an example http://googlemapsapi.blogspot.com/2007/05/driving-dir开发者_开发百科ections-support-added-to.html
Is the source code available somewhere or a tutorial on that precise example ?
Here's a very basic example using the v3 API:

directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('panel'));
var request = {
origin: 'Chicago',
destination: 'New York',
travelMode: google.maps.DirectionsTravelMode.DRIVING

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

Code to get route, legs and other data using Latitude/longitude OR using Address without google map in JavaScript using v3 API:
<script src="https://maps.googleapis.com/maps/api/js?v=3&key=<key>&libraries=places"></script>
<script>
var directionsService = new google.maps.DirectionsService();
var start_lat = "41.8781136";
var start_lon = "-87.6297982";
var end_lat = "40.7127753";
var end_lon = "-74.0059728";
// Using Latitude and longitude
var request = {
origin: new google.maps.LatLng(start_lat, start_lon),
destination: new google.maps.LatLng(end_lat, end_lon),
optimizeWaypoints: true,
avoidHighways: false,
avoidTolls: false,
travelMode: google.maps.TravelMode.DRIVING
};
//Using plain address
// var request = {
// origin: { query: "Chicago, IL, USA" },
// destination: { query: "New York, NY, USA" },
// travelMode: google.maps.TravelMode.DRIVING,
// };
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
var route = response.routes[0];
var leg = response.routes[0].legs[0];
var polyline = route.overview_polyline;
var distance = route.legs[0].distance.value;
var duration = route.legs[0].duration.value;
console.log(route); // Complete route
console.log(distance); // Only distance
console.log(duration); // Only duration
console.log(leg); // Route options/list
console.log(polyline); // Polyline data
}
});
</script>
