  • vue 使用高德地图vue-amap组件

    首先    npm install -S vue-amap



    然后在 main.js
    import VueAMap  from 'vue-amap';  //注意不要和 AMap原始名称覆盖
    Vue.use(VueAMap);
    // 初始化vue-amap
    VueAMap.initAMapApiLoader({
      // 高德的key
      key: 'you key',
      // 插件集合
      plugin: ['AMap.Autocomplete', 'AMap.PlaceSearch', 'AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.PolyEditor', 'AMap.CircleEditor','AMap.Geolocation'],
      v: '1.4.4'
    	
    });
    

     

     map.vue文件

     其中有个BUS.js,是基于观察者模式的发布订阅封装
