remove route with google map

Question

I got a small app that use the Direction Service feature of Google Map. It is working well, I can change routes, but I have a small problem, where a user could go back to a list of markers after tracing a route.

I can't find a way to delete routes with google map. For markers I store them and do setMap(null), do not see a way here...

Answer 1

You could also use:

directionsDisplay.setDirections({routes: []}); 

In this way, you can keep using one map with one renderer for all routes.

Answer 2

if you are using DirectionsRenderer to display the routes, you can call setMap(null) on it too. That way you delete the displayed route.

Using the example code here http://code.google.com/apis/maps/documentation/javascript/examples/directions-simple.html

just call

directionsDisplay.setMap(null);
