Question

i mix geolocation and a form input for a route planner.
After changing the adress in the form or using geolocation the map works great.
But the directions in the directionsDisplay.setPanel are not changing 🙁

Heres my code:

EDIT:
i just realised that i get the new directions. But the old directions are not deleted. They show up one below the other…

Answer 1

Keep a reference to the previous DirectionsRenderer and call .setMap(null) when you want to disabled it.
