第一步 去高德地图开放平台申请密钥
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（）
我要评论
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
