这篇文章主要介绍了vue 使用高德地图vue-amap组件过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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
