问题 I've made a Google Map that show a location at the beginning with 1 marker. From there you have the possibility to switch location. It will then show the new location with 1 marker.

I thought that making 2 vars ( for each location 1) would be the best thing [example]: var locationsBerlin = [ ['Berlin 1', 52.519433,13.406746, 1], ['Berlin 2', 52.522606,13.40366, 2], ['Berlin 3', 52.52113

You do then need the locations of the stops. proof of concept fiddle var map; function initMap() { map = new google.maps.Map(document.getElementById('map'), {
