地图

基于多种地图平台（百度，谷歌，高德）Javascript API 的地图组件，其中百度，高德支持ie8+，谷歌ie9+。

何时使用

需要显示或获取空间数据的时候。

浏览器支持

百度，高德支持IE8+，谷歌IE9+

安装

npm install @gem-mine/rc-map --save

运行

# 默认开启服务器，地址为 ：http://local:8000/

# 能在ie9+下浏览本站，修改代码后自动重新构建，且能在ie10+运行热更新，页面会自动刷新
npm run start

# 构建生产环境静态文件，用于发布文档
npm run site

代码演示

.react-map-demo {
  width: 100%;
  height: 500px;
}
.react-map-container-demo .button-demo {
  margin: 5px;
}
