這篇文章主要介紹了vue-cli中使用高德地圖的方法示例，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

第一步去高德地圖開(kāi)放平臺(tái)申請(qǐng)密鑰高德地圖開(kāi)放平臺(tái)

第二部在vue-cli項(xiàng)目目錄結(jié)構(gòu)

里面多了config文件夾和 utils文件夾

config.js里面是這樣的主要是導(dǎo)出密鑰

// 高德地圖 key
export const MapKey = '你的密鑰key'
// 地圖限定城市
export const MapCityName = '武漢'

utils文件夾里面新建路一個(gè)remoteLoad.js

主要是動(dòng)態(tài)創(chuàng)建script標(biāo)簽封裝了一個(gè)函數(shù) 傳入U(xiǎn)RL地址（）

export default function remoteLoad (url, hasCallback) {
 return createScript(url)
 /**
  * 創(chuàng)建script
  * @param url
  * @returns {Promise}
  */
 function createScript (url) {
  var scriptElement = document.createElement('script')
  document.body.appendChild(scriptElement)
  var promise = new Promise((resolve, reject) => {
   scriptElement.addEventListener('load', e => {
    removeScript(scriptElement)
    if (!hasCallback) {
     resolve(e)
    }
   }, false)

   scriptElement.addEventListener('error', e => {
    removeScript(scriptElement)
    reject(e)
   }, false)

   if (hasCallback) {
    window.____callback____ = function () {
     resolve()
     window.____callback____ = null
    }
   }
  })

  if (hasCallback) {
   url += '&callback=____callback____'
  }

  scriptElement.src = url

  return promise
 }

 /**
  * 移除script標(biāo)簽
  * @param scriptElement script dom
  */
 function removeScript (scriptElement) {
  document.body.removeChild(scriptElement)
 }
}

第三步在Home組件中

<template>
 <div class="m-map">
  <div class="search" v-if="placeSearch">
   <input type="text" placeholder="請(qǐng)輸入關(guān)鍵字" v-model="searchKey">
   <button type="button" @click="handleSearch">搜索</button>
   <div id="js-result" v-show="searchKey" class="result"></div>
  </div>
  <div id="js-container" class="map"></div>
 </div>
</template>

<script>
import remoteLoad from '@/utils/remoteLoad.js'
import { MapKey, MapCityName } from '@/config/config'
export default {
 props: ['lat', 'lng'],
 data () {
  return {
   searchKey: '',
   placeSearch: null,
   dragStatus: false,
   AMapUI: null,
   AMap: null
  }
 },
 watch: {
  searchKey () {
   if (this.searchKey === '') {
    this.placeSearch.clear()
   }
  }
 },
 methods: {
  // 搜索
  handleSearch () {
   if (this.searchKey) {
    this.placeSearch.search(this.searchKey)
   }
  },
  // 實(shí)例化地圖
  initMap () {
   // 加載PositionPicker，loadUI的路徑參數(shù)為模塊名中 'ui/' 之后的部分
   let AMapUI = this.AMapUI = window.AMapUI
   let AMap = this.AMap = window.AMap
   AMapUI.loadUI(['misc/PositionPicker'], PositionPicker => {
    let mapConfig = {
     zoom: 16,
     cityName: MapCityName
    }
    if (this.lat && this.lng) {
     mapConfig.center = [this.lng, this.lat]
    }
    let map = new AMap.Map('js-container', mapConfig)
    // 加載地圖搜索插件
    AMap.service('AMap.PlaceSearch', () => {
     this.placeSearch = new AMap.PlaceSearch({
      pageSize: 5,
      pageIndex: 1,
      citylimit: true,
      city: MapCityName,
      map: map,
      panel: 'js-result'
     })
    })
    // 啟用工具條
    AMap.plugin(['AMap.ToolBar'], function () {
     map.addControl(new AMap.ToolBar({
      position: 'RB'
     }))
    })
    // 創(chuàng)建地圖拖拽
    let positionPicker = new PositionPicker({
     mode: 'dragMap', // 設(shè)定為拖拽地圖模式，可選'dragMap'、'dragMarker'，默認(rèn)為'dragMap'
     map: map // 依賴(lài)地圖對(duì)象
    })
    // 拖拽完成發(fā)送自定義 drag 事件
    positionPicker.on('success', positionResult => {
     // 過(guò)濾掉初始化地圖后的第一次默認(rèn)拖放
     if (!this.dragStatus) {
      this.dragStatus = true
     } else {
      this.$emit('drag', positionResult)
     }
    })
    // 啟動(dòng)拖放
    positionPicker.start()
   })
  }
 },
 async created () {
  // 已載入高德地圖API，則直接初始化地圖
  if (window.AMap && window.AMapUI) {
   this.initMap()
  // 未載入高德地圖API，則先載入API再初始化
  } else {
   await remoteLoad(`http://webapi.amap.com/maps?v=1.3&key=${MapKey}`)
   await remoteLoad('http://webapi.amap.com/ui/1.0/main.js')
   this.initMap()
  }
 }
}
</script>

<style lang="css">
.m-map{ min-width: 500px; min-height: 300px; position: relative; }
.m-map .map{ width: 100%; height: 100%; }
.m-map .search{ position: absolute; top: 10px; left: 10px; width: 285px; z-index: 1; }
.m-map .search input{ width: 180px; border: 1px solid #ccc; line-height: 20px; padding: 5px; outline: none; }
.m-map .search button{ line-height: 26px; background: #fff; border: 1px solid #ccc; width: 50px; text-align: center; }
.m-map .result{ max-height: 300px; overflow: auto; margin-top: 10px; }
</style>

第四步在app.vue中導(dǎo)入組件

<template>
 <div id="app">
  <div class="g-wraper">
   <div class="m-part">
    <mapDrag @drag="dragMap" class="mapbox"></mapDrag>
   </div>
  </div>

 </div>
</template>

<script>
import mapDrag from './components/Home.vue'
export default {
 name: 'app',
 components: {
  mapDrag
 },
 data () {
  return {
   dragData: {
    lng: null,
    lat: null,
    address: null,
    nearestJunction: null,
    nearestRoad: null,
    nearestPOI: null
   }
  }
 },
 methods: {
  dragMap (data) {
   console.log(data)
   this.dragData = {
    lng: data.position.lng,
    lat: data.position.lat,
    address: data.address,
    nearestJunction: data.nearestJunction,
    nearestRoad: data.nearestRoad,
    nearestPOI: data.nearestPOI
   }
  }
 }
}
</script>

<style>
body{ margin: 0; }
.page-header{
 color: #fff; text-align: center; background: #159957;
 background-image: -webkit-linear-gradient(330deg,#155799,#159957);
 background-image: linear-gradient(120deg,#155799,#159957);
 padding: 3rem 4rem; margin-bottom: 30px;
}
.page-header h1{ margin: 0; font-size: 40px; }
.page-header p{ color: #ccc; margin: 0; margin-bottom: 30px; }
.page-header a{ display: inline-block; border: 1px solid #fff; margin-right: 10px; line-height: 40px; padding: 0 20px; border-radius: 4px; color: #fff; text-decoration: none; transition: all .3s; }
.page-header a:hover{ background: #fff; color: #333; }
.g-wraper{ width: 1000px; margin: 0 auto; color: #666; font-size: 16px; line-height: 30px; }
.m-part{ margin-bottom: 30px; }
.m-part::after{ content: ''; display: block; clear: both; }
.m-part .title{ font-size: 30px; line-height: 60px; margin-bottom: 10px; color: #333; }
.m-part .mapbox{ width: 600px; height: 400px; margin-bottom: 20px; float: left; }
.m-part .info{ margin: 0; padding: 0; list-style: none; line-height: 30px; margin-left: 620px; }
.m-part .info span{ display: block; color: #999; }
.m-part ol{ line-height: 40px; margin-left: 0; padding-left: 0; }
.m-part pre{ padding: 10px 20px; line-height: 30px; border-radius: 3px; box-shadow: 0 0 15px rgba(0,0,0,.5); }
.m-footer{ background: #eee; line-height: 60px; text-align: center; color: #999; font-size: 12px; }
.m-footer a{ margin: 0 5px; color: #999; text-decoration: none; }
</style>

上面地圖初始化渲染的方法直接拿別人封裝好的東西

最后運(yùn)行后
