Turn on / off markers in the Google Maps API v3

Question

I'm having trouble getting setMap (null); a feature that everyone seems to recommend working.

I believe this may be a problem with how I implemented markers.

If someone can take a look and let me know, if you see something wrong, I would really appreciate it.

29              markersTest[i].setMap(null);
30          }
31      }
32  }

addTestMarkers, markersTest , . clearOverlays markersTest .

: markersTest, javascript markerDestinations, javascript markersTest,

markersTest = {};

addTestMarkers :

function addTestMarkers() {
    for(var i in markerDestinations) {
        var location = new google.maps.LatLng(markersDestinations[i][1], markersDestinations[i][2]);
        markersTest[i] = new google.maps.Marker({
            position: location,
            map: map
        });
    }
