Why are you rendering the directions again after setting the
routeIndex? That sets it back to 0 (I suspect).
If I comment out this line in the renderDirections alternate-route
change function:
// renderDirections(directionsDisplay.directions);
this works:
directionsDisplay.setRouteIndex(parseInt($('#alternate-
route').attr('value')));
(it doesn't like it if I leave out the "parseInt"...)
