And apparently GDirections is a dynamic class which allows me to add
properties to it like this:
for(r=0; r<activeRides.length; r++)
{
rides[r] = new GDirections(map);
rides[r].my_r = r;
...
GEvent.addListener(rides[r], "load", function (e)
{
alert("my r = " + this.my_r); //<<<-------- alerts the
value of r correctly !!!
alert(this.getDistance().meters);
}
);
}
I can still use help with questions 1 and 3 , though.
Best regards,
Marv
