After discovering the solution on my own, I realized that it is indeed possible thanks to jfvanderwalt for providing the helpful link to the Google Docs for Direction API. This led me to a working example of what I needed and how to implement it. You can view my working demo here.
Javascript :
<script>
var rendererOptions = {
draggable: true
};
var directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions);;
var directionsService = new google.maps.DirectionsService();
var map;
var australia = new google.maps.LatLng(41.171418,28.311553);
function initialize() {
var mapOptions = {
zoom: 4,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: australia
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('directionsPanel'));
google.maps.event.addListener(directionsDisplay, 'directions_changed', function() {
computeTotalDistance(directionsDisplay.directions);
});
calcRoute();
}
function calcRoute() {
var request = {
origin: 'Istanbul, Turkey',
destination: 'Ankara, Turkey',
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
function computeTotalDistance(result) {
var total = 0;
var time= 0;
var from=0;
var to=0;
var myroute = result.routes[0];
for (var i = 0; i < myroute.legs.length; i++) {
total += myroute.legs[i].distance.value;
time +=myroute.legs[i].duration.text;
from =myroute.legs[i].start_address;
to =myroute.legs[i].end_address;
}
time = time.replace('hours','H');
time = time.replace('mins','M');
total = total / 1000.
document.getElementById('from').innerHTML = from + '-'+to;
document.getElementById('duration').innerHTML = time ;
document.getElementById('total').innerHTML =Math.round( total)+"KM" ;
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
HTML:
<div id="map-canvas" style="margin-left:15px;float:left;width:930px; height:280px"></div>
<div style="float:left;padding-left:20px; padding-top:15px; width:100%; height: 80px;">
<div style="float:left;width: 50%;"><h3 id="from"></h3></div>
<div style="float:right;margin-right: 20px;width: 158px;text-align: right;">
<h3 id="duration"></h3>
