Referencing draggable route waypoints.

[ironcito]

Hello!

A user drags a route and creates a waypoint. How do I reference that
waypoint? For example, if I want to know its position, or delete it
when the user right-clicks it.

Thanks in advance!

I don't think the drag operation results in a waypoint (at least that
you can access).

I don't know that you can get access to it to delete it.

You can process the results object to find the start and end of each
step; but I don't know that the dragged location will appear in that.

You can do it all manually, but that loses some of the coolness of the
new draggable directions.

You could probably create a feature request for access to the
waypoints used to create the final route.

The waypoints that are added by dragging seem to create a
via_waypoint[] array to the DirectionsLeg object of DirectionsResult.

via_waypoint[] array contains objects that have properties:

location (LatLng)
step_index (number)
step_interpolation (number)
