Leaflet (markerCluster + searchControl)：如何在搜索时打开弹出窗口之前对集群进行蜘蛛搜索

// 创建Leaflet地图实例
var map = L.map('map').setView([51.505, -0.09], 13);

// 添加地图图层
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors',
    maxZoom: 18
}).addTo(map);

// 创建markerCluster实例
var markerCluster = L.markerClusterGroup();

// 添加需要聚合的标记
var marker1 = L.marker([51.5, -0.09]);
var marker2 = L.marker([51.51, -0.1]);
markerCluster.addLayers([marker1, marker2]);

// 创建searchControl实例
var searchControl = new L.Control.Search({
    layer: markerCluster,
    propertyName: 'name',
    marker: false,
    moveToLocation: function(latlng, title, map) {
        // 在搜索结果点击时展开聚集的标记
        markerCluster.zoomToShowLayer(latlng, function() {
            latlng.layer.openPopup();
        });
    }
});

// 将searchControl添加到地图上
map.addControl(searchControl);
