如何在开放层地图中的标记单击上设置蜘蛛视图标记？

Question

我创建了开放层地图，并使用一些动态纬度和经度在地图中设置了标记一些纬度和经度值相同单击标记时如何打开蜘蛛视图

   let path = this.props.waypts;

        path.map((lat,index)=>{
            let fill = new style.Fill({color:'rgba(255,255,255,1)'}),
            stroke = new style.Stroke({color:'rgba(0,0,0,1)'}),
            style1 = [
                new style.Style({
                    image: new style.Icon(({
                        scale: .9, 
                        opacity: 1,
                        rotateWithView: false, 
                        anchor: [0.5, 1],
                        anchorXUnits: 'fraction', 
                        anchorYUnits: 'fraction',
                        src: "https://img.icons8.com/metro/40/"+(this.props.color[index]).replace( /#/g, "" )+"/marker.png"
                    })),
                    zIndex: 5
                }),
                new style.Style({
                    image: new style.Circle({
                        radius: 6, 
                        fill: fill, 
                        stroke: stroke
                    }),
                    zIndex: 4
                })
            ];

            let abc = 'feature'+[index+1];               
            abc = new Feature({
                geometry: new geom.Point(path[index])
            });
            abc.setStyle(style1);
            sourceFeatures.addFeatures([abc]);
        })

        map.getView().fit(sourceFeatures.getExtent(), map.getSize());

查看ol-ext中的ol / interaction / SelectCluster。选择后，群集会弹开以显示其中的功能。在线查看示例：https://viglino.github.io/ol-ext/examples/animation/map.animatedcluster.html
