Sorry, no link yet.
But a (quite tricky) solution:
function initialize()
{
map = new GMap2(document.getElementById("map_canvas"));
map.setCenter(new GLatLng(66.00,33.00), 15);
map.addControl(new GSmallMapControl());
getDirections ('Address 1', 'Address 2');
}
function getDirections (fromAddr, toAddr)
{
var panel= document.getElementById("panel");
directions = new GDirections(null, panel);
directions.load("from: " +fromAddr+ " to: "+toAddr, { getPolyline:
true, preserveViewport: false } );
GEvent.addListener(directions,'load', showDirections);
}
function setMarkers()
{
var startMarker = new GMarker(directions.getMarker(0).la);
var endMarker = new GMarker(directions.getMarker(1).la)
map.addOverlay(startMarker);
map.setCenter(startMarker.la, 12);
map.addOverlay(endMarker);
GEvent.addListener(startMarker, "click", function() {
startMarker.openInfoWindowHtml('<p>This is the start
point.</p>');
});
GEvent.addListener(endMarker, "click", function() {
endMarker.openInfoWindowHtml('<p>This is the end point.</p>');
});
}
function showDirections()
{
setMarkers();
var points = [];
var poly = directions.getPolyline();
for (var i = 0; i < poly.getVertexCount(); i++) {
points[i] = poly.getVertex(i);
}
var mypoly = new GPolyline(points, "#ff0000", 3, 1);
map.addOverlay(mypoly);
}
$(window).ready(function()
{
initialize();
});
It's not too nice an by no means finished but works.
Thanks for all your help!
