一、参考资料

高德开放平台 | 高德地图API (amap.com)

二、安装及配置

pnpm i @vuemap/vue-amap --save

man.ts 密钥及安全密钥需要自己到高德地图开放平台控制台获取.

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import vant from 'vant'
import 'vant/lib/index.css'
import VueAMap, { initAMapApiLoader } from '@vuemap/vue-amap'
import '@vuemap/vue-amap/dist/style.css'

import * as echarts from 'echarts'

initAMapApiLoader({
  key: '841d5250cb7f61adda2ee70c1e3abdaf',
  securityJsCode: 'd122cbf5a33de34356661cf0cef1a553', // 新版key需要配合安全密钥使用
  plugins: [
    // 定位空间，用来获取和展示用户主机所在的经纬度位置
    'AMap.Geolocation',
    // 输入提示插件
    'AMap.Autocomplete',
    // POI搜索插件
    'AMap.PlaceSearch',
    // 右下角缩略图插件，比例尺
    'AMap.Scale',
    // 地图鹰眼插件
    'AMap.OverView',
    // 地图工具条
    'AMap.ToolBar',
    // 类别切换空间，实现默认图层与卫星图，实施交通层之间切换的控制
    'AMap.MapType',
    // 编辑 折线多边形
    'AMap.PolyEditor',
    'AMap.CircleEditor',
    // 地图编码
    'AMap.Geocoder'
  ]
})

const app = createApp(App)
//全局挂载echarts
app.config.globalProperties.$echarts = echarts
app.use(router)
app.use(ElementPlus)
app.use(VueAMap)
app.use(vant)
app.mount('#app')

三、源码分享

1、map.vue

<template>
  <el-dialog v-model="showMapDialog">
    <template #default>
      <div id="container">
        <AmapSelect v-model="locationData" @callback="getMapInfo" />
      </div>
    </template>
  </el-dialog>
</template>

<script lang="ts" setup>
import { ref, nextTick, defineEmits } from 'vue'
// import { ElMessage } from 'element-plus';
import AmapSelect from './AmapSelect.vue'

const props = defineProps({
  title: {
    type: String,
    default: '选择位置'
  },

  center: {
    type: Array,
    default: () => [115.846381, 28.659961]
  }
})

const locationData:any = ref([])
const showMapDialog = ref(false)
const emit = defineEmits(['submit'])

function getMapInfo(info: any) {
  // console.log(info,'info'); 可拿到点击的地址 以及经纬度  可用于做回显等其他操作
  // debugger
  emit('submit', {
    address: info.address,
    lnglat: info.lnglat
  })
}

const openForm = () => {
  showMapDialog.value = true
  nextTick(() => {
    locationData.value=props.center;
  })
}

//提交

// const okModal = async () => {}

//导出方法

defineExpose({
  openForm
})
</script>

<style lang="scss" scoped>
#container {
  height: 400px;
}

.el-dialog__body {
  padding: 0 !important;
}
</style>

2、AmapSelect.vue

<template>
  <el-amap :zoom="zoom" @init="init">
    <el-amap-search-box
      :visible="visible"
      @select="selectChange"
      @choose="handleChange"
      placeholder="请输入"
    />

  </el-amap>
</template>

<script>
export default {
  name: 'AmapSelect',

  emits: ['callback'],

  props: {
    visible: {
      type: Boolean,
      default: true
    },

    modelValue: {
      type: Array,
      default: []
    }
  },

  data() {
    return {
      zoom: 12,
      map: null,
      geocoder: new AMap.Geocoder({}),
      activeAddress: null,
    }
  },

  watch: {
    modelValue: {
      handler(val, oldVal) {
        if (val) {
          // let lnglat = val[1].split(',')

          this.onClickMap({
            lnglat: { lng: val[0], lat: val[1] }
          })
        }
      },

      deep: true
    }
  },

  mounted() {},

  methods: {
    init(map) {
      this.map = map

      map.on('click', this.onClickMap.bind(this))
    },

    selectChange({ poi }) {
      if (poi.location) {
        let { lng, lat } = poi.location

        this.onClickMap(
          {
            lnglat: { lng, lat }
          },

          () => {
            this.map.setCenter([lng, lat])
          }
        )
      }
    },

    handleChange(e) {
      console.log('handleChange: ', e)
    }, 
    
    
    // 点击地图
    onClickMap(e, callback) {
      let lnglat = [e.lnglat.lng, e.lnglat.lat]

      var infoWindow = new AMap.InfoWindow({
        offset: new AMap.Pixel(0, 0)
      })

      this.geocoder.getAddress(lnglat, (status, result) => {
