有没有一种方法可以将位置添加到使用JavaScript随机放置在Google地图中的标记的标签上？

Question

Is it possible to add the LatLng to the label of the marker that is placed at random to show where that marker is? Also considering the infoWindow option but have not been successful yet.

var map;
var markers = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var markersIndex = 0;

function initialize() {
    var Wilm = new google.maps.LatLng(34.2257,-77.9447);
    var mapOptions = {
        zoom: 12,
        center: Wilm,
        mapTypeId: google.maps.MapTypeId.TERRAIN
    }
    map = new google.maps.Map(document.getElementById('map-
    canvas'),mapOptions);



    google.maps.event.addListener(map, 'click', function(event) {
            addMarker(event.latLng);
    });


}

function addMarker(location) {

        var marker = new google.maps.Marker({
        position: location,
        label: markers[markersIndex++ % markers.length],
        map: map
    });
    google.maps.event.addListener(marker, 'rightclick', function(event) {
            marker.setMap(null);
    });

    markers.push(marker);
}

google.maps.event.addDomListener(window, 'load', initialize);

Not sure what you mean by a label.

this will add markers to the map with an info window with the latlng:

    function initMap() {
  var Wilm = new google.maps.LatLng(34.2257, -77.9447);
  var mapOptions = {
    zoom: 12,
    center: Wilm,
    mapTypeId: google.maps.MapTypeId.TERRAIN
  }
  map = new google.maps.Map(document.getElementById('map'), mapOptions);

  google.maps.event.addListener(map, 'click', function(event) {
    placeMarker(event.latLng);
  });
}

function placeMarker(location) {


  var marker = new google.maps.Marker({
    position: location,
    map: map
  });

  var contentString = 'Lat' + marker.getPosition().lat() + ', lng:  ' + marker.getPosition().lng();

  var infowindow = new google.maps.InfoWindow({
    content: contentString
  });

  marker.addListener('click', function() {
    infowindow.open(map, marker);
  });
}

 function initMap() { var Wilm = new google.maps.LatLng(34.2257, -77.9447); var mapOptions = { zoom: 12, center: Wilm, mapTypeId: google.maps.MapTypeId.TERRAIN } map = new google.maps.Map(document.getElementById('map'), mapOptions); google.maps.event.addListener(map, 'click', function(event) { placeMarker(event.latLng); }); } function placeMarker(location) { var marker = new google.maps.Marker({ position: location, map: map }); var contentString = 'Lat' + marker.getPosition().lat() + ', lng: ' + marker.getPosition().lng(); var infowindow = new google.maps.InfoWindow({ content: contentString }); marker.addListener('click', function() { infowindow.open(map, marker); }); }
