I am trying to create a map app using google maps API. My aim is to
get some locations as input from the user (as string of addresses like
"Mountain view, CA"... etc), store those strings in an array and then
use that array as an input to a function that can in an iterative
manner calculate the driving distance between every pair of address in
the array and store those distances in a new 2-D array where ,
dist[i][j] = driving distance b/w i and j
dist[i][j] = 0 for i = j
dist[i][j] = dist [j][i]
while searching for solutions to the problem I did come across some
potential solutions like -
http://briancray.com/2009/06/23/calculate-driving-distance-google-maps-api
but the solution provided here calculates the driving distance between
any 2 addresses that are entered by the user in 2 separate forms. My
question is how can I sort of automate this process while using an
array as the input?(Like using a loop or something to do this, i am
not pretty sure about this)
I am pasting the code I have made so far here (As i don't have a
domain of my own).
It just takes as input an address and puts a marker on that location &
prints all the points that the user has marked so far.
//Code

<script type="text/javascript">
var map = null;
var geocoder = null;
var list = new Array();
var i = 0;
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(28° 40' 0, 77° 13' 0), 13);
geocoder = new GClientGeocoder();
map.setUIToDefault();
}
}
function AddAddress(address) {
if (geocoder) {
geocoder.getLatLng(
address,
function(point) {
if (!point) {
alert(address + " not found");
} else {
map.setCenter(point, 13);
var marker = new GMarker(point);
map.addOverlay(marker);
marker.openInfoWindowHtml(address);
list[i]=address;
i++;
document.getElementById("List").innerHTML=list;
}
}
);
}
}

<body onload="initialize()" onunload="GUnload()">
