I'm using the GDirections, and start off with the default Driving Mode
directions, but for points that are close together (less than 3 miles,
or something), I give an option to toggle between walking and driving
directions. As of now, I toggle between the travel modes by calling
loadFromWayPoints again:
doDirections: function(type) {
if(type != G_TRAVEL_MODE_WALKING) {
type = G_TRAVEL_MODE_DRIVING;
}
this.directionsInstance.loadFromWaypoints([
fromLatLng, toLatLng
],{'travelMode': type});
}
Since I don't want to hit Google more than necessary, I'm wondering if
there is any way to cache the results of the directions query so that
a second toggle-to-walking or toggle-to-driving won't result in a
second call to the Google servers.
It wouldn't surprise me if this is already taken care of in the
GDirections class, and if that's the case, super.
