Google API maps how to set a constant?

Question

Google

There is an example of building a map with autocomplete - how to set a static origin address?

Answer 1

directionsService.route({
origin: {'placeId': "ChIJq6qqWiSsEmsRJuIpepyEua4"}

Answer 2

If you look at the example, then you need to know the placeId for the starting point.

// вместо place.place_id вам нужно захардкодить какой-нибудь идентификатор
    origin_place_id = place.place_id; // например  origin_place_id = "ChIJq6qqWiSsEmsRJuIpepyEua4"
    route(origin_place_id, destination_place_id, travel_mode,
          directionsService, directionsDisplay);
