1、首先引入高德地图api地址，key要去高德开发平台去申请。
<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=''&plugin=AMap.MarkerClusterer"></script>
申请步骤：点击控制台——点击我的应用创建一个应用就会得到key。

2、在页面引入 import AMap from 'AMap' 如果不引用new AMap会报红
3、在vue.config文件中写入
configureWebpack: () => {
const configNew = {}
configNew.externals = {
AMap: 'AMap' // 高德地图配置
}
return configNew
},
4、我们要去实现我们的功能了
<template>
<div>
<div id="mapView" style="width:100%; height:calc(100vh - 306px);"> </div>
<div class="tabs">
<div class="tabs-view" v-for="item in tabsList" :key="item.name" @click="tabsClick(item.name)">
<img :src="tabsActive==item.name?item.active:item.normal"/>
<p :class="tabsActive==item.name?'tabs-p':''">{{item.title}}</p>
</div>
</div>
</div>
</template>
