vue-cli中使用高德地图的方法示例
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; } </style>
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 .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
