This code save in the variable "drivingDistanceKilometers" the
distance between two points by road:
-----------------------
function distance(p1,p2){
var geocoder, location1, location2, gDir;
geocoder = new GClientGeocoder();
gDir = new GDirections();
geocoder.getLocations(p1, 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(p2);
location2 = {lat:
response.Placemark[0].Point.coordinates[1], lon:
response.Placemark[0].Point.coordinatesGEvent.addListener(gDir,
"load", function() {
var drivingDistanceKilometers = gDir.getDistance().meters /
1000;
alert(drivingDistanceKilometers);
});[0], address: response.Placemark[0].address};
gDir.load('from: ' + p1 + ' to: ' + p2);
}
});
GEvent.addListener(gDir, "load", function() {
var drivingDistanceKilometers = gDir.getDistance().meters /
1000;
alert(drivingDistanceKilometers);
});
//return (drivingDistanceKilometers);
}
-----------------------
and run ok but I need return "drivingDistanceKilometers" to work with
this date.
If I write "return (drivingDistanceKilometers);" in the end function
this return undefined.
How can I return "drivingDistanceKilometers" after event load to not
be undefined?
Thanks.
