Here is a link to the working code:

I;m having trouble getting the "Start" field to show the address location
instead of the coordinates. I know I have to use reverse geocoding but I'm
not sure how to go about it. Note: I am using the W3C geolocation to get the
users current location. Any help is greatly appreciated.
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
var myOptions = {
zoom:7,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: chicago
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById("directionsPanel"));
geocoder = new GClientGeocoder();
}
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
browserSupportFlag = true;
navigator.geolocation.getCurrentPosition(function(position) {
initialLocation = new
google.maps.LatLng(position.coords.latitude,position.coords.longitude);
map.setCenter(initialLocation);
document.getElementById('start').value = initialLocation;
}, function() {
handleNoGeolocation(browserSupportFlag);
});
// Try Google Gears Geolocation
} else if (google.gears) {
browserSupportFlag = true;
var geo = google.gears.factory.create('beta.geolocation');
geo.getCurrentPosition(function(position) {
initialLocation = new
google.maps.LatLng(position.latitude,position.longitude);
map.setCenter(initialLocation);
document.getElementById('start').value = initialLocation;
}, function() {
handleNoGeoLocation(browserSupportFlag);
});
// Browser doesn't support Geolocation
} else {
browserSupportFlag = false;
handleNoGeolocation(browserSupportFlag);
}
function handleNoGeolocation(errorFlag) {
if (errorFlag == true) {
alert("Geolocation service failed.");
initialLocation = newyork;
} else {
alert("Your browser doesn't support geolocation. We've placed you in
Siberia.");
initialLocation = siberia;
}
map.setCenter(initialLocation);
}
function calcRoute() {
var start = document.getElementById("start").value;
var end = document.getElementById("end").value;
var request = {
origin:start,
destination:end,
travelMode: google.maps.TravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
