Vue引入高德地图实现流程分步讲解

作者：清雨未尽时

这篇文章主要介绍了Vue引入高德地图实现流程，实现步骤是通过vue的方法引入地图，初始化地图，设置宽和高，本文通过实例代码给大家介绍的非常详细，需要的朋友可以参考下

一、功能需求

1.根据输入内容进行模糊查询，选择地址后在地图上插上标记，并更新经纬度坐标显示

2.在地图点击后，根据回传的左边更新地址信息和坐标显示

二、准备

1.申请高德地图账号，创建应用

2.在应用管理中 获得key 和安全密钥

三、在webstorm中安装

npm i @amap/amap-jsapi-loader -S

四、防止在使用中AMap无法识别问

在eslintrc.js中加入配置:

  globals:{
    "AMap": "true"
  }

五、正式开发

1.创建页面

<template>
  <div>
    <label>消息管理</label>
    <div style="margin-top: 20px">
      <div style="height:520px;">
        <div id="all" style="height:100%">
          <div class="posInput">
            <el-input style="width:100%"
                      id="tipinput"
                      class="form-control input-style"
                      type="text"
                      placeholder="请输入搜索地址"
                      prefix-icon="el-icon-search"
                      v-model="formatAdress"
            >
            </el-input>
          </div>
          <div id="allmap"></div>
          <div class="posSubmit">
            <el-form  ref="form"  label-width="85px" >
              <div class="btn_box" >
                <el-form-item label="经度:" >
                  <el-input style="width:400px" disabled class="form-control input-style" type="text" v-model="longitude"> </el-input>
                </el-form-item>
                <el-form-item label="纬度:" >
                  <el-input style="width:400px"  disabled class="form-control input-style" type="text" v-model="latitude"> </el-input>
                </el-form-item>
              </div>
            </el-form>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

2.页面样式

<style scoped>
#all{
  position: relative;
}
#allmap{
  width: 100%;  height: calc(100%  - 50px);
  font-family: "微软雅黑";
}
.posInput{
  position: absolute;
  z-index: 1;
  width: 80%;
  margin-top: 20px;  margin-left: 10%;
}
.posSubmit{
  position: absolute; z-index: 1; bottom: 0;
  margin-left: 5%;
  width: 90%;
  display: flex;  justify-content: flex-start; align-items: center;
}
.btn_box{
  width: 100%;
  height: 100%;
  display: flex;  ; align-items: center;
}
::v-deep .el-form-item{
  margin-bottom: 0 !important;
}
</style>

3.存储的数据项

data () {
    return {
      map: null,
      marker: null,
      startSeacrh: [],
      stratInfo: {},
      dprops: {
        zoom: 15
      },
      formatAdress: '',
      longitude: '', // 经度
      latitude: '', // 纬度
    }
  }

4.创建地图方法

  mounted () {
    this.initMap()
  },
  methods: {
    initMap () {
      const that = this
      init('allmap', that.dprops).then(AMap => {
        that.map = AMap
        that.map.on('click', that.clickHandler) // 地图点击事件 可获取经纬度等信息
        initScaleTools(that.map, true, false)
        searchAutocomplete(that.map, 'tipinput', function (event) {
          that.handleStartSelect(event)
        })
      }).catch(err => {
        this.$message.error(err)
      })
    },
    clickHandler (event) {
      console.log(event, '起点经纬度 [lng,lat]')
      if (event.lnglat === '') {
        this.$message({
          type: 'warning',
          message: '该地点无经纬度数据，请输入具体一点的地点!',
          duration: 5 * 1000
        })
        return
      }
      if (this.marker) {
        this.map.remove(this.marker)
        this.marker = null
      }
      this.startSeacrh = []
      this.startSeacrh = [event.lnglat.lng, event.lnglat.lat]
      this.marker = new AMap.Marker({
        position: this.startSeacrh
      })
      this.map.add(this.marker)
      this.map.setCenter(this.startSeacrh)
      this.longitude = event.lnglat.lng
      this.latitude = event.lnglat.lat
      let that = this
      getAddressByLngLat(this.startSeacrh, function (status, result) {
        if (status === 'complete') {
          that.formatAdress = result.regeocode.formattedAddress
          let adrComponent = result.regeocode.addressComponent
          that.stratInfo = {
            district: adrComponent.province,
            address: adrComponent.district,
            name: adrComponent.township + adrComponent.street + adrComponent.streetNumber,
            fullAdr: result.regeocode.formattedAddress
          }
        }
      })
    },
    handleStartSelect (event) {
      console.log(event, '起点经纬度 [lng,lat]')
      if (event.poi.location === '') {
        this.$message({
          type: 'warning',
          message: '该地点无经纬度数据，请输入具体一点的地点!',
          duration: 5 * 1000
        })
        return
      }
      if (this.marker) {
        this.map.remove(this.marker)
        this.marker = null
      }
      this.startSeacrh = []
      this.startSeacrh = [event.poi.location.lng, event.poi.location.lat]
      this.formatAdress = event.poi.district + event.poi.address + event.poi.name
      this.longitude = event.poi.location.lng
      this.latitude = event.poi.location.lat
      this.marker = new AMap.Marker({
        position: this.startSeacrh
      })
      this.map.add(this.marker)
      this.map.setCenter(this.startSeacrh)
      this.stratInfo = {
        district: event.poi.district,
        address: event.poi.address,
        name: event.poi.name,
        fullAdr: this.formatAdress
      }
    }
  }

5.封装好的js文件方法

initMap.js

import AMapLoader from '@amap/amap-jsapi-loader'
window._AMapSecurityConfig = {
  securityJsCode: '安全密钥'
}
const initMap = async (config) => {
  return new Promise((resolve, reject) => {
    AMapLoader.load({
      'key': config.key,
      'version': '1.4.15',
      'plugins': [
        'AMap.PolygonEditor' // 插件
      ],
      'AMapUI': {
        'version': '1.1',
        'plugins': []
      },
      'Loca': {
        'version': '1.3.2'
      }
    }).then((AMap) => {
      resolve(AMap)
    }).catch(err => {
      reject(err)
    })
  })
}
export default initMap

map.js

import initMap from './initMap.js'
export const init = (container, props) => {
  const config = {
    key: 'key'
  }
  return new Promise((resolve, reject) => {
    initMap(config).then(AMap => {
      resolve(new AMap.Map(container, { ...props }))
    }).catch(err => {
      reject(err)
    })
  })
}
/**
 * @param {*} map 地图实例
 * @param {Boolean} noScale 不需要比例尺  true表示不需要
 * @param {Boolean} noToolBar 不需要工具栏 true表示不需要
 */
export const initScaleTools = (map, noScale, noToolBar) => {
  if (!noScale) {
    map.plugin(['AMap.Scale'], function () {
      var scale = new AMap.Scale()
      map.addControl(scale)
    })
  }
  if (!noToolBar) {
    map.plugin(['AMap.ToolBar'], function () {
      var tool = new AMap.ToolBar()
      map.addControl(tool)
    })
  }
}
//模糊查询
export const searchAutocomplete = (map, keyword, commpletHandle) => {
  map.clearMap()
  AMap.plugin(['AMap.PlaceSearch', 'AMap.Autocomplete'], function () {
    let autoOptions1 = { input: keyword, city: '全国' }
    let startAutoComplete = new AMap.Autocomplete(autoOptions1)
    AMap.PlaceSearch({
      map: map
    })
    AMap.event.addListener(startAutoComplete, 'select', commpletHandle)
  })
}
/**
 *
 * @param {String} LngLat 经纬度
 * @param {Function} callback 回调函数
 * @param {Object} otherProps 其他参数
 */
export const getAddressByLngLat = (LngLat, callback, otherProps) => {
  AMap.plugin('AMap.Geocoder', function () {
    let geocoder = new AMap.Geocoder({
      ...otherProps
    })
    geocoder.getAddress(LngLat, function (status, result) {
      callback(status, result)
    })
  })
}
const mapJS = {
  init,
  initScaleTools,
  searchAutocomplete,
  getAddressByLngLat
}
export default mapJS

在文件中导入 map.js方法

import {
  init,
  initScaleTools,
  searchAutocomplete,
  getAddressByLngLat
} from '../../utils/map'

六、步骤总结

1.在mounted（）中调用initMap ()初始化地图

2.初始化成功后、添加事件监听：地图点击、模糊查询。添加放大缩小工具栏

init('allmap', that.dprops).then(AMap => {
        that.map = AMap
        that.map.on('click', that.clickHandler) // 地图点击事件 可获取经纬度等信息
        initScaleTools(that.map, true, false)
        searchAutocomplete(that.map, 'tipinput', function (event) {
          that.handleStartSelect(event)
        })
      })
