Hii,
I try to find polylines by given waypoints.
But if one of the given waypoints can not calculated, error event is
fired.
I mean,
dirndeneme = new GDirections();
GEvent.addListener(dirndeneme,"error", function() {
var polyLine = this.getPolyline();
//var routess = this.getRoute(0);
if (!polyLine)
{alert('route Null');}
alert('error');
});
GEvent.addListener(dirndeneme,"load", function() {
var distance = this.getDistance().meters;
alert('Distance from-to:'+ distance);
var polyLine = this.getPolyline();
gMap.addOverlay(polyLine);
});
var fromLatLon = 50+","+15;
var toLatLon = 53+","+12;
var toLatLon2 = 45+","+5;
var GDirectionsDenemeOption = {getSteps:false, getPolyline:true};
dirndeneme.load("from: " + fromLatLon+ " to: " + toLatLon + " to: "
+ toLatLon2 , GDirectionsDenemeOption);
This working fine. load event is fired and I can get polyline by
getPolyline method.
But if I add
var toLatLon3 = 40+","+30; (In the point in Turkey.)
And load function is:
dirndeneme.load("from: " + fromLatLon+ " to: " + toLatLon + " to: "
+ toLatLon2 + " to: " + toLatLon3, GDirectionsDenemeOption);
Because of last point, error event is fired and I can not get previous
polylines.
Is it the case? Or is there a way to get previous (calculated)
polylines?
I think that GDirections can be calculate polylines even if there is
point which can not be calculated.
For example When I try to get polylines by getRoute(i:Number)
function, It may return null for these waypoints.
Why not? Or do I miss something?
Thanks for your help.
