Markercluster spiderfy - Максимальный уровень масштабирования карты отображает группы значков маркеров вместо вида кластера с количеством

Question

Markercluster spiderfy - Максимальный уровень масштабирования карты отображает группы значков маркеров вместо вида кластера с количеством

1

При выполнении кода мы можем видеть представление кластера с подсчетом 3. После нажатия на кластер он масштабируется до максимального уровня масштабирования и отображает представление кластера со счетом 3. В этом максимальном уровне масштабирования я хотел отобразить значок маркера вместо кластерного представления со счетом 3. После щелчка по группам значков маркера, он должен spiderfy.

Вы хотите сказать, что вместо 3 вам нужен значок маркера?

Ты можешь использовать

 var markerClusters = L.markerClusterGroup({iconCreateFunction: function(cluster) {
        return L.divIcon({ html: '<div class="markerImage">' + cluster.getChildCount() + '</div>' });
    }});

.markerImage{
  
background-image:url("https://image.shutterstock.com/image-vector/map-pin-flat-design-style-450w-627403736.jpg");
background-size: cover;
    border: 0;
    background-color: transparent;
    width: 100px;
    height: 100px;
}

.leaflet-marker-icon{
background:transparent !important;
border:0px !important;
}
