高德地图模糊搜索地址（elementUI）

首先引入AMap：

1、在index.html引入AMap

<script type="text/javascript" src="http://webapi.amap.com/maps?v=1.4.6&key=你申请的key&plugin=AMap.Geocoder"></script>
<script src="http://webapi.amap.com/ui/1.0/main.js"></script>

2、在build/webpack.base.conf.js中找到module.exports，在末尾添加以下代码：

externals: {
   'AMap': 'AMap'
}

3、在需要调用地图的文件中导入AMap，就可以直接调用AMap的API

import AMap from 'AMap'

注意：

本例中只用到了AMap.Geocoder插件，如果要调用其他的plugin，如AMap.Driving，需要在index.html相应加载（多个plugin用逗号隔开）：

<script type="text/javascript" src="http://webapi.amap.com/maps?v=1.4.6&key=你申请的key&plugin=AMap.Driving,AMap.Geocoder"></script>
