GoogleMaps Markerclusterer InfoWindow же местоположение, кластер получает контент от маркеров

Question

У меня проблема, MarkerCluster undefined content from Markers.

Я использовал MarkerCluster в тот же адрес (местоположение) gridSize: 1

При нажатии кластера zoomOnClick: ложь, кластер должен getMarkers содержание

и открытый InfoWindow. но я получаю undefined undefined.

Я щелку эту проблему на этом

google.maps.event.addListener(markerCluster, 'clusterclick', function(cluster) { 
    var markers = cluster.getMarkers(); 

    var content = ''; 
    for (var i = 0; i < markers.length; i++) { 
     var marker = markers[i]; 
     content += marker.name; 
     content += ("<br>"); 
    } 
    var infowindow = new google.maps.InfoWindow(); 
    infowindow.setPosition(cluster.getCenter()); 
    infowindow.close(); 
    infowindow.setContent(content); 
    infowindow.open(map); 
    google.maps.event.addListener(map, 'zoom_changed', function() { 
     infowindow.close(); 
    }); 
    }); 

Полный код:

function initMap() { 
     var map = new google.maps.Map(document.getElementById('map'), { 
      center: new google.maps.LatLng(55.7522200, 37.6155600), 
      zoom: 11 
     }); 

     var infoWindow = new google.maps.InfoWindow; 

    var iconPurple = new google.maps.MarkerImage('mapimages/purple.svg', new google.maps.Size(33, 31)); 
    var iconBlue = new google.maps.MarkerImage('mapimages/blue.svg', new google.maps.Size(33, 31)); 
    var iconYellow = new google.maps.MarkerImage('mapimages/yellow.svg', new google.maps.Size(33, 31)); 
    var iconGreen = new google.maps.MarkerImage('mapimages/green.svg', new google.maps.Size(33, 31)); 
    var iconPink = new google.maps.MarkerImage('mapimages/pink.svg', new google.maps.Size(33, 31)); 
    var iconBrown = new google.maps.MarkerImage('mapimages/brown.svg', new google.maps.Size(33, 31)); 

    var customIcons = []; 
    customIcons["room1"] = iconPurple; 
    customIcons["room2"] = iconBlue; 
    customIcons["room3"] = iconYellow; 
    customIcons["room4"] = iconGreen; 
    customIcons["room5"] = iconPink; 
    customIcons["room6"] = iconBrown; 

var options = {

В google.maps.Marker объекты в MarkerClusterer не то же самое "маркер" XML элементы, которые вы обрабатываете, чтобы создать google.maps.Markers. У вас не будет свойства name, если только вы его не создали.

var marker = new google.maps.Marker({ 
    map: map, 
    position: point, 
    icon: customIcons[type], 
    animation: google.maps.Animation.DROP, 
    name: name // <-- add this 
});
