vue 使用高德地图vue-amap组件过程解析

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
