vue-cli中使用高德地图
第一步 去高德地图开放平台申请密钥 高德地图开放平台
第二部 在vue-cli项目目录结构
里面多了config文件夹和 utils文件夹
config.js里面是这样的 主要是导出密钥
// 高德地图 key
export const MapKey = '你的密钥key'
// 地图限定城市
export const MapCityName = '武汉'
utils文件夹里面 新建路一个remoteLoad.js
主要是动态创建script标签 封装了一个函数 传入URL地址（）
export default function remoteLoad ( url, hasCallback) {
return createScript( url)
/**
* 创建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标签
* @param scriptElement script dom
*/
function removeScript ( scriptElement) {
document. body. removeChild( scriptElement)
}
}
第三步 在Home组件中
< template >
< div class= "m-map" >
< div class= "search" v-if=" placeSearch" >
< input type= "text" placeholder= "请输入关键字" 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)
}
},
// 实例化地图
initMap () {
// 加载PositionPicker，loadUI的路径参数为模块名中 '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)
// 加载地图搜索插件
AMap. service( 'AMap.PlaceSearch', () => {
this. placeSearch = new AMap. PlaceSearch({
pageSize: 5,
pageIndex: 1,
citylimit: true,
city: MapCityName,
map: map,
panel: 'js-result'
})
})
// 启用工具条
AMap. plugin([ 'AMap.ToolBar'], function () {
map. addControl( new AMap. ToolBar({
position: 'RB'
}))
})
// 创建地图拖拽
let positionPicker = new PositionPicker({
mode: 'dragMap', // 设定为拖拽地图模式，可选'dragMap'、'dragMarker'，默认为'dragMap'
map: map // 依赖地图对象
})
// 拖拽完成发送自定义 drag 事件
positionPicker. on( 'success', positionResult => {
// 过滤掉初始化地图后的第一次默认拖放
if (! this. dragStatus) {
this. dragStatus = true
} else {
this. $emit( 'drag', positionResult)
}
})
// 启动拖放
positionPicker. start()
})
}
},
async created () {
// 已载入高德地图API，则直接初始化地图
if ( window. AMap && window. AMapUI) {
this. initMap()
// 未载入高德地图API，则先载入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; }

第四步 在app.vue中 导入组件
< 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 .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; }

上面 地图初始化渲染的方法 直接拿别人封装好的东西
最后运行后
