一、申请高德key和秘钥

• 申请高德key
  
• 申请成功后可以得到key
  

二、在项目中引入所需功能js、css文件

<script src="https://webapi.amap.com/maps?v=2.0&key=XXXXXXXXXXXXX"></script>
<script src="https://a.amap.com/jsapi_demos/static/demo-center/js/demoutils.js"></script>
<link rel="stylesheet" href="https://a.amap.com/jsapi_demos/static/demo-center/css/demo-center.css" />
<scripttype="text/javascript"src="https://webapi.amap.com/demos/js/liteToolbar.js"
></script>

三、实现地图选点、回显选点

<template><el-dialog title="选择地址" :visible.sync="MapVisible" width="960px"><el-formref="Addressform":model="Addressform":rules="Addressrules"label-width="65px"><el-row><el-col :span="6"><el-form-item label="省" prop="province"><el-selectv-model="Addressform.provinceId"placeholder=""filterablestyle="width: 100%"@change="changeProvince"><el-optionv-for="dict in provinceOptions":key="dict.id":label="dict.name":value="dict.id"/></el-select></el-form-item></el-col><el-col :span="6"><el-form-item label="市" prop="city"><el-selectv-model="Addressform.cityId"filterableplaceholder=""style="width: 100%"@change="changeCity"><el-optionv-for="dict in cityOptions":key="dict.id":label="dict.name":value="dict.id"/></el-select></el-form-item></el-col><el-col :span="6"><el-form-item label="区" prop="region"><el-selectv-model="Addressform.regionId"placeholder=""filterablestyle="width: 100%"@change="changeRegion"><el-optionv-for="dict in regionOptions":key="dict.id":label="dict.name":value="dict.id"/></el-select></el-form-item></el-col><el-col :span="6"><el-form-item label="乡(镇)" prop="street"><el-selectv-model="Addressform.streetId"placeholder=""filterablestyle="width: 100%"@change="changeStreet"><el-optionv-for="dict in streetOptions":key="dict.id":label="dict.name":value="dict.id"/></el-select></el-form-item></el-col></el-row><el-row style="display: flex; align-items: end"><el-col :span="20"><el-form-item label="村" prop="village"><el-inputtype="textarea":autosize="{ minRows: 2, maxRows: 4 }"placeholder="请输入村"v-model="Addressform.village"></el-input></el-form-item></el-col><el-col :span="4"><el-form-item label="" label-width="20px"><el-buttontype="primary"icon="el-icon-search"size="mini"@click="searchAddress":disabled="!Addressform.streetId">搜索</el-button></el-form-item></el-col></el-row></el-form><div id="mapselectpoint-container"></div><span slot="footer" class="dialog-footer"><el-button @click="MapVisible = false">取 消</el-button><el-buttontype="primary"@click="submitAddress":disabled="!point || !Addressform.streetId">确 定</el-button></span></el-dialog>

四、自定义地图

• 自定义地图
  

  this.map = new AMap.Map("mapselectpoint-container", {zoom: 15.8,//   center: [116.469881, 39.993599], //不设置自动定位到当前所在城市mapStyle: "amap://styles/8c825bfe70db32d900edb766197db660", //设置地图的显示样式});//添加如下代码即可this.map.setMapStyle("amap://styles/你的自定义地图ID");
