在vue中使用高德地图的上浮下钻—最简单明了的方法(无需后台接口渲染文字marker)

在vue中使用高德地图的上浮下钻—最简单明了的方法(无需后台接口渲染文字marker)

第一步：

安装vue-amap：

npm i vue-amap -S

第二步:

配置main.js

import VueAMap from 'vue-amap'
Vue.use(VueAMap);
VueAMap.initAMapApiLoader({key: '你的key',plugin: ['AMap.Autocomplete', 'AMap.PlaceSearch', 'AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.PolyEditor', 'AMap.CircleEditor','AMap.ControlBar','AMap.MouseTool','AMap.GeometryUtil','AMap.DistrictSearch'],// 默认高德 sdk 版本为 1.4.4v: '1.4.4',uiVersion:'1.0.11'
});

第三步：
