Hi There
I am trying to show a route on a map ...
So I have say 10 places I want to visit in that route so I create a
string like "from: -33.918755, 151.226293 to: -33.901500, 151.214972
to: -33.883360, 151.194047 to: -33.892990, 151.205410 to: -33.918755,
151.226293"
and then overlay the polyline ...
directions = new GDirections(map);
GEvent.addListener(directions, 'load', foobar);
directions.load(routes, {getPolyline:true});
function foobar() {
var polyline = directions.getPolyline();
map.addOverlay(polyline);
}
I notice that when the points are many and I construct a string with
from: and to: it doesnt seem to work but the load(query:String,
queryOpts?:GDirectionsOptions) does not seem to have any limit on the
number of points.....unline loadFromWaypoints(waypoints:Array,
queryOpts?:GDirectionsOptions) from the api........
When I create my own polyline and over lay the polyline as shown
below I have no such problem... I can overlay as many points as I
want...
var points = [
new GLatLng(41.08 , -81.4),
];
var polyline = new GPolyline(points, '#ff0000', 5, 0.7);
// Add the polyline to the map using map.addOverlay()
map.addOverlay(polyline);
Could anyone help me out here
Cheers
Priya
