高德官方api:高德官方开放平台
一、注册并登录高德开放平台获取(key和秘钥)
引用:
<script>import AMapLoader from '@amap/amap-jsapi-loader';window._AMapSecurityConfig = {securityJsCode: '**************************',//你的秘钥} </script>
二、安装高德依赖
npm i @amap/amap-jsapi-loader --save
三、初始化地图
封装公共的地图组件:
<map-container :positionInfo ='positionInfo' @select ='getLocationInfo'></map-container>
mounted() {this.initMap() }, methods:{initMap(){AMapLoader.load({key:"**********************", // 申请好的Web端开发者Key,首次调用 load 时必填version:"2.0",// 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15plugins: [//需要使用的插件'AMap.ToolBar','AMap.Scale','AMap.Geolocation','AMap.PlaceSearch','AMap.AutoComplete','AMap.Geocoder','AMap.CitySearch'],resizeEnable: true,}).then((AMap)=>{const that = this;that.map = new AMap.Map("container",{//设置地图容器idviewMode:"3D",//是否为3D地图模式zoom:12,//初始化地图级别}); }).catch(e=>{console.log(e); }) },
四、首次打开地图获取当前定位并标记
initMap(){ AMapLoader.load({key:"*******************", // 申请好的Web端开发者Key,首次调用 load 时必填version:"2.0",// 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15plugins: ['AMap.ToolBar','AMap.Scale','AMap.Geolocation','AMap.PlaceSearch','AMap.AutoComplete','AMap.Geocoder','AMap.CitySearch'],resizeEnable: true,}).then((AMap)=>{const that = this;that.map = new AMap.Map("container",{//设置地图容器idviewMode:"3D",//是否为3D地图模式zoom:12,//初始化地图级别});that.getCurrentLocation();//获取当前定位that.geocoder = new AMap.Geocoder()that.map.addControl(new AMap.Scale())// 在图面添加比例尺控件,展示地图在当前层级和纬度下的比例尺that.map.addControl(new AMap.ToolBar())//在图面添加鹰眼控件,在地图右下角显示地图的缩略图}).catch(e=>{console.log(e);})},//获取当前定位getCurrentLocation(){const that = this;that.geolocation = new AMap.Geolocation({timeout: 3000,//超过3秒后停止定位,默认:5senableHighAccuracy: true,zoomToAccuracy: true, //定位成功后是否自动调整地图视野到定位点});that.geolocation.getCurrentPosition(function(status,result){//备注:getCurrentPosition方法会调用超时或失败://Get geolocation time out:浏览器定位超时,包括原生的超时,可以适当增加超时属性的设定值以减少这一现象。//另外还有个别浏览器(如google Chrome浏览器等)本身的定位接口是黑洞,通过其请求定位完全没有回应,也会超时返回失败。//Get geolocation failed:定位失败,Chrome、火狐以及部分套壳浏览器接入的定位服务在国外,有较大限制,失败率高。console.log(status,result);if(status=='complete'){that.onComplete(result)}else{that.onError(result) //失败后可使用getCityInfo获取非精准定位(具体到省市)}});},//解析定位结果onComplete(data) {console.log('定位结果:' + data.position) //经纬度信息let lnglat = data.position;let marker = new AMap.Marker({//创建标记position: new AMap.LngLat(lnglat[0], lnglat[1])})this.map.clearMap()// 清除所有覆盖物(点标志)this.map.add(marker)// 添加点标志let that = this//经纬度转换为中文地址详情that.geocoder.getAddress(lnglat, function (status, result) {if (status === 'complete' && result.regeocode) {that.address = result.regeocode.formattedAddress;that.showInfoWindow(marker);//自定义信息窗体} else {that.$message.error('根据经纬度查询地址失败')}})},//解析定位错误信息onError(data) {this.getLngLatLocation()},//在获取具体定位失败时调用的代码:(非精准定位!!!)getLngLatLocation() {const that = this;that.geolocation.getCityInfo(function (status, result) {if (status === 'complete') {let data = result.positionthat.address = result.province + result.city;that.showLocation(data)} else {that.$message.error('获取地址失败')}})},
五、根据已有地址自动定位到指定地址并标记
initMap(){ AMapLoader.load({key:"*******************", // 申请好的Web端开发者Key,首次调用 load 时必填version:"2.0",// 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15plugins: ['AMap.ToolBar','AMap.Scale','AMap.Geolocation','AMap.PlaceSearch','AMap.AutoComplete','AMap.Geocoder','AMap.CitySearch'],resizeEnable: true,}).then((AMap)=>{const that = this;that.map = new AMap.Map("container",{//设置地图容器idviewMode:"3D",//是否为3D地图模式zoom:15, //初始化地图级别center:[that.positionInfo.lng,that.positionInfo.lat]; // 首次加载地图自动加载到指定位置中心});that.showLocation(data) //新增标记并展示信息窗体that.map.addControl(new AMap.Scale())// 在图面添加比例尺控件,展示地图在当前层级和纬度下的比例尺that.map.addControl(new AMap.ToolBar())//在图面添加鹰眼控件,在地图右下角显示地图的缩略图}).catch(e=>{console.log(e);})},
六、新增、清除标记及自定义信息窗体
//新增标记showLocation(data){ let marker = new AMap.Marker({ position: new AMap.LngLat( data[0],data[1]) //参数为经纬度 }) this.map.clearMap()// 清除所有覆盖物(点标志) this.map.add(marker)// 添加点标志 this.showInfoWindow(marker);//自定义信息窗体 },//自定义信息窗体showInfoWindow(marker){let infoWindow = new AMap.InfoWindow({isCustom: true, //是否自定义信息窗体content:` 地址:${this.address}`,closeWhenClickMap: true,zIndex: 999,offset: new AMap.Pixel(16, -35)});infoWindow.open(this.map, marker.getPosition());},
七、鼠标点击地图并选点标记
initMap(){ AMapLoader.load({key:"*******************", // 申请好的Web端开发者Key,首次调用 load 时必填version:"2.0",// 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15plugins: ['AMap.ToolBar','AMap.Scale','AMap.Geolocation','AMap.PlaceSearch','AMap.AutoComplete','AMap.Geocoder','AMap.CitySearch'],resizeEnable: true,}).then((AMap)=>{const that = this;that.map = new AMap.Map("container",{//设置地图容器idviewMode:"3D",//是否为3D地图模式zoom:12, //初始化地图级别});that.geocoder = new AMap.Geocoder()that.map.addControl(new AMap.Scale())// 在图面添加比例尺控件,展示地图在当前层级和纬度下的比例尺that.map.addControl(new AMap.ToolBar())//在图面添加鹰眼控件,在地图右下角显示地图的缩略图 that.handleClick(AMap)//地图选点}).catch(e=>{console.log(e);})}, //点击地图获取地理位置handleClick(){this.map.on('click', (e) => {let lng = e.lnglat.lnglet lat = e.lnglat.latlet marker = new AMap.Marker({position: new AMap.LngLat(lng, lat)})this.map.clearMap()// 清除所有覆盖物(点标志)this.map.add(marker)// 添加点标志let lnglat = [lng, lat]let that = thisthat.geocoder.getAddress(lnglat, function (status, result) {if (status === 'complete' && result.regeocode) {that.address = result.regeocode.formattedAddress;that.showInfoWindow(marker);//自定义信息窗体 let thisPosition = { address: that.address, lng: lng, lat: lat};that.$emit("select",thisPosition) //返回给父组件} else {that.$message.error('根据经纬度查询地址失败')}})})},
八、根据关键字搜索并自动定位
//搜索框及搜索结果选择窗<template><div>//搜索框<div class="map-box"><div class="label">关键字搜索</div><el-inputv-model="mapAddress"placeholder="请输入内容"id="tipinput"@keyup.enter.native="searchKeyWord"></el-input><el-button type="primary" @click="searchKeyWord"icon="el-icon-search" ></el-button></div>//搜索结果选择窗<div class="map_search_result"v-if="showSearchResult"><ul><li@click="markerResult(item)" v-for="(item,index) in poiList" :key="index">{{item.name}}</li></ul></div>//地图<div id="container" :style="{width: width, height: height}"></div></div></template>
initMap(){ AMapLoader.load({key:"*******************", // 申请好的Web端开发者Key,首次调用 load 时必填version:"2.0",// 指定要加载的 JSAPI 的版本,缺省时默认为 1.4.15plugins: ['AMap.ToolBar','AMap.Scale','AMap.Geolocation','AMap.PlaceSearch','AMap.AutoComplete','AMap.Geocoder','AMap.CitySearch'],resizeEnable: true,}).then((AMap)=>{const that = this;that.map = new AMap.Map("container",{//设置地图容器idviewMode:"3D",//是否为3D地图模式zoom:12, //初始化地图级别});that.handleClick(AMap)//地图选点that.map.addControl(new AMap.Scale())// 在图面添加比例尺控件,展示地图在当前层级和纬度下的比例尺that.map.addControl(new AMap.ToolBar())//在图面添加鹰眼控件,在地图右下角显示地图的缩略图that.geocoder = new AMap.Geocoder()that.mapSearchInit()}).catch(e=>{console.log(e);})},
/** 初始化搜索 */mapSearchInit(){ let autoOptions = { input: "tipInput", } let autoCompleteComponent= new AMap.Autocomplete(autoOptions); this.autoCompleteComponent = autoCompleteComponent; // 注册placeSearch组件 this.placeSearchComponent = new AMap.PlaceSearch() }, //根据输入内容查询 searchKeyWord(){ let that= this that.placeSearchComponent.search(that.mapAddress, function (status, result) { if(status==='complete' && result.info === "OK"){ that.showsearchResult = true that.poiList = result.poiList.pois }else{ that.showsearchResult = false that.poiList = [] that.$message({ message: "没有查到结果", type: "warning", }); } }) }, //选择搜索的内容 markerResult(data){ this.showsearchResult = false; this.address = data.name; var marker = new AMap.Marker({ position: [Number(data.location.lng),Number(data.location.lat)], }); this.map.clearMap()// 清除所有覆盖物(点标志) this.map.add(marker)// 添加点标志 this.showInfoWindow(marker); setTimeout(() => { this.map.setCenter(data.location); this.map.setZoom(15); }, 50) let thisPosition = { address: this.address, lng: data.location.lng, lat: data.location.lat }; this.$emit("select",thisPosition) },
