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>最终实现效果
