I'm trying to work out how to use the Google Maps Directions Demo to get the distance from the successful directions.
This is the code I have so far:
var googleMaps = {
// HTML Nodes
fromInput: google_maps_from,
toInput: google_maps_to,
// API Objects
dirService: new google.maps.DirectionsService(),
dirRenderer: new google.maps.DirectionsRenderer(),
map: null,
showDirections: function(dirResult, dirStatus) {
if (dirStatus != google.maps.DirectionsStatus.OK)
{
//Here we'll handle the errors a bit better :P
alert('Directions failed: ' + dirStatus);
return;
}
else
{
//Get the distance here
//onGDirectionsLoad();
}
// Show directions
googleMaps.dirRenderer.setMap(googleMaps.map);
googleMaps.dirRenderer.setPanel(document.getElementById("directions"));
googleMaps.dirRenderer.setDirections(dirResult);
},
getSelectedTravelMode: function() {
return google.maps.DirectionsTravelMode.DRIVING;
},
getSelectedUnitSystem: function() {
return google.maps.DirectionsUnitSystem.METRIC;
},
getDirections: function() {
var fromStr = googleMaps.fromInput;
var toStr = googleMaps.toInput;
var dirRequest = {
origin: fromStr,
destination: toStr,
travelMode: googleMaps.getSelectedTravelMode(),
unitSystem: googleMaps.getSelectedUnitSystem(),
provideTripAlternatives: true
};
googleMaps.dirService.route(dirRequest, googleMaps.showDirections);
},
init: function() {
googleMaps.map = new google.maps.Map(document.getElementById("map_canvas"), {
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
// Show directions onload
googleMaps.getDirections();
}
};
// Onload handler to fire off the app.
google.maps.event.addDomListener(window, 'load', googleMaps.init);
I could do this just fine in v2, just having trouble working out the v3 equivalent.

The API returns information based on the recommended route between start and end points. You can request distance data for different travel modes, request distance data in different units such kilometers or miles, and estimate travel time in traffic.
The Distance Matrix API uses a pay-as-you-go pricing model.
While it does not seem to be documented officially, it looks like you can traverse the response from the DirectionsService.route() method: response.trips[0].routes[0].distance.value, as in the following example:

directionsDisplay.setMap(map);
var request = {

};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
// Display the distance:
document.getElementById('distance').innerHTML +=
response.routes[0].legs[0].distance.value + " meters";
// Display the duration:
document.getElementById('duration').innerHTML +=
response.routes[0].legs[0].duration.value + " seconds";
directionsDisplay.setDirections(response);
}
});
