地图插件文档：[https://elemefe.github.io/vue-amap/\#/][https_elemefe.github.io_vue-amap]

下载引入插件

npm install --save vue-amap

在main全局引用插件

// 引入vue-amap
    import VueAMap from 'vue-amap';
    // 初始化vue-amap
    Vue.use(VueAMap);
    VueAMap.initAMapApiLoader({
      // 高德的key
      key: '****************',
      // 插件集合
      plugin: ['AMap.Autocomplete', 'AMap.PlaceSearch',
       'AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.PolyEditor', 
       'AMap.CircleEditor','Geocoder'],
      // 高德 sdk 版本，默认为 1.4.4
      v: '1.4.4'
    });

写一个地图组件  views/components/gd-map.vue  方便项目中多处使用

    </script>
    
    <style>
    .amap-page-container {
      width: 100%;
      height: 500px;
    }
    .search-box {
      position: absolute;
      top: 65px;
      left: 20px;
    }
    .map-content {
      height: 90%;
    }
    </style>

在使用页面引入组件

import gdMap from '@/views/components/gd-map'
    
    export default {
      // 注册组件
      components: {gdMap}
    
    }

页面调用进行选点获取经纬度信息

<div>
           
          <gdMap :changeCall="changeAddressCall" :locationInfo="locationInfo"></gdMap>
    </div>
    
    <script>
    import gdMap from '@/views/components/gd-map'
      export default {
      // 注册组件
      components: {gdMap},
     data() {
          return {
            form:{},
            // 默认初始化显示的坐标
            locationInfo:{
                iocn:"",
                name:"",
                longitude:"", // 经度
                latitude:"", // 纬度
                address:"" // 地址
            }
        }
     },
      methods: {
          // 获取经纬度，地址信息回调方法
          changeAddressCall(address,lng,lat){
            this.form.address=address;
            this.form.longitude=lng;
            this.form.latitude=lat;
          },
      }
    }
    
    </script>

table中根据经纬度弹出Dialog   地位位置信息

dialog地图信息组件 showMapDialog

<template>
      <el-dialog
        :title="title"
        :visible.sync="isShow"
        :width="width"
        :before-close="handleClose"
        @closed="closed"
      >
        <gdMap :locationInfo="showLocationInfo"></gdMap>
      </el-dialog>
    </template>
    
    <script>
    import gdMap from "@/views/components/gd-map";
    export default {
      components: {
        gdMap,
      },
      data() {
        return {
          isShow: this.value,
          showLocationInfo: this.locationInfo,
        };
      },
      props: {
        locationInfo: {
          type: Object,
          default: null,
        },
        title: {
          type: String,
          default: null,
        },
    
        transactionGroupType: {
          type: String,
          default: null,
        },
        value: {
          type: Boolean,
          default: false,
        },
        width: {
          type: String,
          default: "60%",
        },
      }, // 图片数组数据
      created() {
        this.locationInfo;
        debugger;
      },
      mounted() {},
      methods: {
        opened() {},
        closed() {
          this.$emit("input", false);
        },
        handleClose() {
          this.isShow = false;
        },
      },
    };
    </script>
    
    <style>
    </style>

页面中根据经纬度显示地图使用

在main中进行全局注册

import showMapDialog from '@/views/components/showMapDialog'
    Vue.component('showMapDialog', showMapDialog)

页面使用

<template>
      <div class="app-container">
    
        <div>
            <el-button size="mini" type="info"  class="el-icon-map-location"  @click="showMpDialog(row)">显示地图</el-button>
        </div>
    
        <showMapDialog :title="showTitle" v-if="isShowDialog" v-model="isShowDialog" :locationInfo="locationInfo" :onlyShowLocation="true"></showMapDialog>
    
      </div>
    </template>
    
    <script>
    
    export default {
      props: {},
      filters: {},
      data() {
        return {
          showTitle:"地图显示",
          isShowDialog:false,
          locationInfo:{
            iocn:"",
            name:"",
            longitude:"", // 经度
            latitude:"" // 纬度
          }
        };
      },
    
      methods: {
        showMpDialog(row){
            this.isShowDialog=true;
            this.locationInfo ={
              iocn:row.snapshoot,
              name:row.name,
              longitude: row.longitude, // 经度
              latitude:row.latitude, // 纬度
              address:row.address
           }
        },
    
      }
    };
    </script>
