drawing routes with google earth js api.

Question

Hi People, I'm starting with a project that use GM api. I need to create routes form the tracklogs from vehicles, but for some reason doesn't work.

This is the code, I'm calling the startMap function first, and then addRouteWaypoints. The map and waypoinps are working fine, but the route is not displayed.

///

var map = null;

//----------------------------------------------------------------------------
function startMap() {

    if (GBrowserIsCompatible()) {

        map = new GMap2(document.getElementById("myMap"));
        map.setMapType(G_NORMAL_MAP);
        map.setCenter(new GLatLng(-34.40, -58.90), 11);
        map.addControl(new GSmallMapControl());
        map.setUIToDefault();
    }

}

//----------------------------------------------------------------------------
function addRouteWaypoints(waypoints) {
    try {

        var wps = new Array();

        for (var i = 0; i < waypoints.split(';').length - 2; i++) {

            lat = waypoints.split(';')[i].split(',')[0];
            lng = waypoints.split(';')[i].split(',')[1];

            //these 2 lines are for test...
            var marker = new GMarker(new GLatLng(lat, lng));
            map.addOverlay(marker);

            latProx = waypoints.split(';')[i + 1].split(',')[0];
            lngProx = waypoints.split(';')[i + 1].split(',')[1];

            wps[i] = new Array(new GLatLng(lat, lng), new
                GLatLng(latProx, lngProx));
        }

        //directionsPanel = document.getElementById("div_DirectionsPanel");
        directions = new GDirections(map);
        GEvent.addListener(
            directions,
            'error',
            function() {
                alert(directions.getStatus().code);
            }
        );

        directions.loadFromWaypoints(wps, { getPolyline: true,
        getSteps: true, travelMode: G_TRAVEL_MODE_DRIVING, preserveViewport:
            false, locale: 'es_ES' });
    }
    catch (err) {
        alert(err.source + ':' + err.message);
    }

}

Thanks.

Try to just draw a polyline - se GPolyline, create it from array and addOverlay()
