Why not have a global variable that counts the outstanding requests.
var requests = 0;
Increment it whenever you issue a request. Decrement it whenever a reply
or a failure comes back.
directions[i].load( ... );
requests++;
GEvent.addListener(directions[i],"load", function() {
distances[i] = directions[i].getDistance().meters;
requests--;
if (requests == 0) {
// finished
}
});
GEvent.addListener(directions[i],"load", function() {
alert("That one failed");
requests--;
if (requests == 0) {
// finished
}
});
