Hi,
I appreciate if someone can help me out on this one as I am not that
familiar with Javascript/Googlemap API.
I am trying to compute network distances between pairs of locations using
google map api using the code below.
The problem is that it only shows the distance result for the last pair
(Point B, Point D).
I believe that onGDirectionsLoad() needs to be corrected to do what I would
like to do.
Eventually, I would like to save the result in .csv or .txt file.
Thank you very much for your help in advance.

}
// Generate pairs of locations
function calcDist()
{
for (var iCnt = 0; iCnt < originArray.length; iCnt++)
{
// Pairs of locations (POL)
direction.clear();
pol = [originArray[iCnt], destinArray[iCnt]];
routeMap(pol);
}
}
// Route identification
function routeMap(pointArray)
{
var option = {locale: 'ja_JP', travelMode:
G_TRAVEL_MODE_DRIVING};
direction.loadFromWaypoints(pointArray, option);
}
// Distance/Duration calcuation
function onGDirectionsLoad()
{
var distance = direction.getDistance();
var duration = direction.getDuration();
for (iCnt = 0; iCnt < originArray.length; iCnt++)
{
document.getElementById("result").innerHTML +=
originArray[iCnt] + " → " + destinArray[iCnt] + " Distance:
" + distance.html + " Time elapsed: " + duration.html + "<br/>";
}
