Vue利用vue-baidu-map實現(xiàn)獲取經(jīng)緯度和搜索地址
在開發(fā)項目的時候,發(fā)現(xiàn)需要獲取經(jīng)緯度,由于這個項目是用vue寫的,最后決定使用vue-baidu-map來快速獲取經(jīng)緯度
基于 Vue.js 封裝的百度地圖組件,運行流暢,代碼簡單易懂,幾乎包含了百度地圖官方的所有API,文檔地址:https://dafrok.github.io/vue-baidu-map/#/zh/start/installation
1.申請百度地圖密鑰
搜索'百度地圖開放平臺',選擇頭部導航欄開發(fā)文檔里的JavaScript API
然后點擊申請密鑰
2.安裝vue-baidu-map
終端運行
npm install vue-baidu-map --save
main.js里全局注冊
import Vue from 'vue' import BaiduMap from 'vue-baidu-map' Vue.use(BaiduMap, { // ak 是在百度地圖開發(fā)者平臺申請的密鑰 詳見 http://lbsyun.baidu.com/apiconsole/key */ ak: 'YOUR_APP_KEY' })
引入組件,初始化地圖,開啟鼠標滾輪控制地圖縮放
<template> <baidu-map id="allmap" @ready="mapReady" :scroll-wheel-zoom="true"> </baidu-map> </template> <script> export default { methods: { //地圖初始化 mapReady({ BMap, map }) { this.point = new BMap.Point(113.27, 23.13); // 選擇一個經(jīng)緯度作為中心點 map.centerAndZoom(this.point, 12); //設置地圖中心點和縮放級別 this.BMap=BMap this.map=map } } } </script> <style> #allmap{ height: 450px; width: 100%; margin: 10px 0; } </style>
一個簡單的地圖就出來了
3.獲取經(jīng)緯度
3.1 為地圖添加點擊事件,獲取經(jīng)緯度
<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信息窗口組件和BmMarker標注,點擊地圖時彈出
<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>緯度:{{this.latitude}}</p> <p>經(jīng)度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </template>
3.3 添加BmAutoComplete組件,輸入地址自動補全
<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="輸入地址"></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>緯度:{{this.latitude}}</p> <p>經(jīng)度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </template>
3.4 最后點擊搜索按鈕地圖跳轉到搜索位置并打開信息窗口和標注
<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>
最后放上全部代碼
<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="輸入地址"></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>緯度:{{this.latitude}}</p> <p>經(jīng)度:{{this.longitude}}</p> </bm-info-window> </baidu-map> </div> </template> <script> export default { data () { return { searchJingwei:'', infoWindowShow:false, longitude:'', latitude:'', point:'' } }, methods: { //地圖初始化 mapReady({ BMap, map }) { // 選擇一個經(jīng)緯度作為中心點 this.point = new BMap.Point(113.27, 23.13); map.centerAndZoom(this.point, 12); this.BMap=BMap this.map=map }, //點擊獲取經(jīng)緯度 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 } }) }, //信息窗口關閉 infoWindowClose(){ this.latitude='' this.longitude='' this.infoWindowShow=false }, }, } </script> <style lang="scss" scoped> #allmap{ height: 450px; width: 100%; margin: 10px 0; } </style>
