在开发项目的时候,发现需要获取经纬度,由于这个项目是用vue写的,最后决定使用vue-baidu-map来快速获取经纬度
基于 Vue.js 封装的百度地图组件,运行流畅,代码简单易懂,几乎包含了百度地图官方的所有API,文档地址:https://dafrok.github.io/vue-baidu-map/#/zh/start/installation
1.申请百度地图密钥
搜索'百度地图开放平台',选择头部导航栏开发文档里的JavaScript API
然后点击申请密钥
2.安装vue-baidu-map
终端运行
npm install vue-baidu-map --save
main.js里全局注册
import Vue from 'vue' import BaiduMap from 'vue-baidu-map' Vue.use(BaiduMap, { // ak 是在百度地图开发者平台申请的密钥 详见 http://lbsyun.baidu.com/apiconsole/key */ ak: 'YOUR_APP_KEY' })
引入组件,初始化地图,开启鼠标滚轮控制地图缩放
<template> <baidu-map id="allmap" @ready="mapReady" :scroll-wheel-zoom="true"> </baidu-map> </template> <script> export default { methods: { //地图初始化 mapReady({ BMap, map }) { this.point = new BMap.Point(113.27, 23.13); // 选择一个经纬度作为中心点 map.centerAndZoom(this.point, 12); //设置地图中心点和缩放级别 this.BMap=BMap this.map=map } } } </script> <style> #allmap{ height: 450px; width: 100%; margin: 10px 0; } </style>
一个简单的地图就出来了
3.获取经纬度
3.1 为地图添加点击事件,获取经纬度
<template> <baidu-map id="allmap" @ready="mapReady" @click="getLocation" :scroll-wheel-zoom="true"> </baidu-map> </template> <script> export default { data () { return { infoWindowShow:false, longitude:'', latitude:'', } }, methods: { getLocation(e){ this.longitude=e.point.lng this.latitude=e.point.lat this.infoWindowShow=true }, } } </script>
3.2 添加BmInfoWindow信息窗口组件和BmMarker标注,点击地图时弹出
<template> <baidu-map id="allmap" @ready="mapReady" @click="getLocation" :scroll-wheel-zoom="true"> <bm-marker v-if="infoWindowShow" :position="{lng: longitude, lat: latitude}"> <bm-label content="" :labelStyle="{color: 'red', fontSize : '24px'}" :offset="{width: -35, height: 30}"/> </bm-marker> <bm-info-window :position="{lng: longitude, lat: latitude}" :show="infoWindowShow" @clickclose="infoWindowClose"> <p>纬度:{{this.latitude}}</p> <p>经度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </template>
3.3 添加BmAutoComplete组件,输入地址自动补全
<template> <baidu-map id="allmap" @ready="mapReady" @click="getLocation" :scroll-wheel-zoom="true"> <div style="display:flex;justify-content:center;margin:15px"> <bm-auto-complete v-model="searchJingwei" :sugStyle="{zIndex: 999999}"> <el-input v-model="searchJingwei" style="width:300px;margin-right:15px" placeholder="输入地址"></el-input> </bm-auto-complete> <el-button type="primary" @click="getBaiduMapPoint">搜索</el-button> </div> <bm-marker v-if="infoWindowShow" :position="{lng: longitude, lat: latitude}"> <bm-label content="" :labelStyle="{color: 'red', fontSize : '24px'}" :offset="{width: -35, height: 30}"/> </bm-marker> <bm-info-window :position="{lng: longitude, lat: latitude}" :show="infoWindowShow" @clickclose="infoWindowClose"> <p>纬度:{{this.latitude}}</p> <p>经度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </template>
3.4 最后点击搜索按钮地图跳转到搜索位置并打开信息窗口和标注
<script> export default { data () { return { infoWindowShow:false, longitude:'', latitude:'', } }, methods: { getBaiduMapPoint(){ let that=this let myGeo = new this.BMap.Geocoder() //逆地址解析 myGeo.getPoint(this.searchJingwei,function(point){ if(point){ that.map.centerAndZoom(point,15) that.latitude=point.lat that.longitude=point.lng that.infoWindowShow=true } }) }, } } </script>
最后放上全部代码
<template> <div> <baidu-map style="display:flex;flex-direction: column-reverse;" id="allmap" @ready="mapReady" @click="getLocation" :scroll-wheel-zoom="true" > <div style="display:flex;justify-content:center;margin:15px"> <bm-auto-complete v-model="searchJingwei" :sugStyle="{zIndex: 999999}"> <el-input v-model="searchJingwei" style="width:300px;margin-right:15px" placeholder="输入地址"></el-input> </bm-auto-complete> <el-button type="primary" @click="getBaiduMapPoint">搜索</el-button> </div> <bm-map-type :map-types="['BMAP_NORMAL_MAP', 'BMAP_HYBRID_MAP']" anchor="BMAP_ANCHOR_TOP_LEFT"></bm-map-type> <bm-marker v-if="infoWindowShow" :position="{lng: longitude, lat: latitude}"> <bm-label content="" :labelStyle="{color: 'red', fontSize : '24px'}" :offset="{width: -35, height: 30}"/> </bm-marker> <bm-info-window :position="{lng: longitude, lat: latitude}" :show="infoWindowShow" @clickclose="infoWindowClose"> <p>纬度:{{this.latitude}}</p> <p>经度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </div> </template> <script> export default { data () { return { searchJingwei:'', infoWindowShow:false, longitude:'', latitude:'', point:'' } }, methods: { //地图初始化 mapReady({ BMap, map }) { // 选择一个经纬度作为中心点 this.point = new BMap.Point(113.27, 23.13); map.centerAndZoom(this.point, 12); this.BMap=BMap this.map=map }, //点击获取经纬度 getLocation(e){ this.longitude=e.point.lng this.latitude=e.point.lat this.infoWindowShow=true }, getBaiduMapPoint(){ let that=this let myGeo = new this.BMap.Geocoder() myGeo.getPoint(this.searchJingwei,function(point){ if(point){ that.map.centerAndZoom(point,15) that.latitude=point.lat that.longitude=point.lng that.infoWindowShow=true } }) }, //信息窗口关闭 infoWindowClose(){ this.latitude='' this.longitude='' this.infoWindowShow=false }, }, } </script> <style lang="scss" scoped> #allmap{ height: 450px; width: 100%; margin: 10px 0; } </style>
