Google Maps API v3: How to remove all markers?

Question

In Google Maps API v2, if I wanted to remove all the map markers, I could simply do:

map.clearOverlays();

How do I do this in Google Maps A

Answer 1

To remove all markers from map create functions something like this:

1.addMarker(location): this function used to add marker on map

2.clearMarkers(): this function remove all markers from map, not from array

3.setMapOnAll(map): this function used to add markers info in array

4.deleteMarkers(): this function Deletes all markers in the array by removing references to them.

// Adds a marker to the map and push to the array.
      function addMarker(location) {
        var marker = new google.maps.Marker({
          position: location,
          map: map
        });
        markers.push(marker);
      }


// Sets the map on all markers in the array.
      function setMapOnAll(map) {
        for (var i = 0; i < markers.length; i++) {
          markers[i].setMap(map);
        }
      }



// Removes the markers from the map, but keeps them in the array.
  function clearMarkers() {
    setMapOnAll(null);
  }

// Deletes all markers in the array by removing references to them.
      function deleteMarkers() {
        clearMarkers();
        markers = [];
      }
