Do you want to use Google Map for calculating distance between two locations. here is the full source code.

	<!-- According to the Google Maps API Terms of Service you are required display a Google map when using the Google Maps API. see: http://code.google.com/apis/maps/terms.html -->
	<script type="text/javascript">

	var geocoder, location1, location2, gDir;

	function initialize() {
		geocoder = new GClientGeocoder();
		gDir = new GDirections();
		GEvent.addListener(gDir, "load", function() {
			var drivingDistanceMiles = gDir.getDistance().meters / 1609.344;
			var drivingDistanceKilometers = gDir.getDistance().meters / 1000;
			document.getElementById('results').innerHTML = '<strong>Address 1: </strong>' + location1.address + ' (' + location1.lat + ':' + location1.lon + ')<br /><strong>Address 2: </strong>' + location2.address + ' (' + location2.lat + ':' + location2.lon + ')<br /><strong>Driving Distance: </strong>' + drivingDistanceMiles + ' miles (or ' + drivingDistanceKilometers + ' kilometers)';
		});
	}

	function showLocation() {
		geocoder.getLocations(document.forms[0].address1.value, function (response) {
			if (!response || response.Status.code != 200)
			{
				alert("Sorry, we were unable to geocode the first address");
			}
			else
			{
				location1 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address};
				geocoder.getLocations(document.forms[0].address2.value, function (response) {
					if (!response || response.Status.code != 200)
					{
						alert("Sorry, we were unable to geocode the second address");
					}
					else
					{
						location2 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address};
						gDir.load('from: ' + location1.address + ' to: ' + location2.address);
					}
				});
			}
		});
	}

	</script>
</head>

<body onload="initialize()">

	<form action="#" onsubmit="showLocation(); return false;">
		<p>
			<input type="text" name="address1" value="Address 1" />
			<input type="text" name="address2" value="Address 2" />
			<input type="submit" value="Search" />
		</p>
	</form>

	<p id="results"></p>

</body>
