Remove marker in Google Maps Api v3

Question

I\'m using this function to add a new marker (and polyline) to a map:

 function addMarker(location) {

    path = poly.getPath();
    path.push(location);
           


        

Answer 1

markersArray[markersArray.length-1].setMap(null);

... for path:

path = poly.getPath();
path.pop();

PolylineOptions, MVCArray.

Answer 2

Last Marker is at the index of markersArray.length -1 so...

markersArray[markersArray.length-1].setMap(null);
