Remove Markers

Read the documentation or view this example full screen.

// In the following example, markers appear when the user clicks on the map.
// The markers are stored in an array.
// The user can then click an option to hide, show or delete the markers.
var map;
var markers = [];

function initMap() {
  var haightAshbury = {lat: 37.769, lng: -122.446};

  map = new google.maps.Map(document.getElementById('map'), {
    zoom: 12,
    center: haightAshbury,
    mapTypeId: 'terrain'
  });

  // This event listener will call addMarker() when the map is clicked.
  map.addListener('click', function(event) {
    addMarker(event.latLng);
  });

  // Adds a marker at the center of the map.
  addMarker(haightAshbury);
}

// 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);
}

// Shows any markers currently in the array.
function showMarkers() {
  setMapOnAll(map);
}

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