uniapp map地图实现marker聚合点，并点击marker触发事件

1.uniapp官方文档说明

2.关键代码片段

	// 仅调用初始化，才会触发 on.("markerClusterCreate", (e) => {})this._mapContext.initMarkerCluster({enableDefaultStyle: false, // 是否使用默认样式zoomOnClick: true, // 点击聚合的点，是否改变地图的缩放级别gridSize: 60, // 聚合计算时网格的像素大小，默认60complete(res) {console.log('initMarkerCluster', res)}});
