vue + 百度地图GL版实现点聚合

npm i bdgl-map-lib

1. 安装 bdgl-map-lib 组件库【持续更新中，需要源码请私我】

2. 注册

此处省略。。。请自行在main.js中注册

3. 使用

4. 注意 

4.1 clusterArr数据必须按照一下格式，其中 id ，location: {lat: "lat", lng: "lng"}， img，chooseImg是必填项  

let clusterArr = [{"id": "210000199408275471","name": "Shirley Anderson","type": "预警","location": {"lat": 36.63537403351243, "lng": 114.78964779606646},"img": "/marker/warning_marker.png","chooseImg": "/marker/warning_marker_choose.png"},{"id": "640000199111161246","name": "Michelle Martin","type": "预警","location": {"lat": 36.23183265585457, "lng": 114.77202363535253},"img": "/marker/warning_marker.png","chooseImg": "/marker/warning_marker_choose.png"},
]
