高德地图的使用 vue-amap+vue

基本配置

1:在vue项目中下载vue-amap

npm install vue-amap --save

文档连接

elemefe.github.io/vue-amap/#/…

2: 在main.js引入高德地图

import VueAMap from 'vue-amap';
//注册高德
Vue.use(VueAMap);
VueAMap.initAMapApiLoader({
  key: '****',//这里是你的高德开发者key
  plugin: ['AMap.Autocomplete', 'AMap.PlaceSearch', 'AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.PolyEditor', 'AMap.CircleEditor'],
  v: '1.4.4'
});
复制代码

使用高德地图 vue-amap报错

地图组件F5刷新会报错 控制台输入

  • Uncaught (in promise) TypeError: v.w.uh is not a constructor
  • Uncaught TypeError: l is not a function
//在main.js增加这段话 (能清除之前缓存的地图信息)
const amapKeys = Object.keys(localStorage).filter(key => key.match(/^_AMap_/))

amapKeys.forEach(key => {
  // console.log(key)
  localStorage.removeItem(key)
})

Vue.use(VueAMap)
复制代码

有时地图加载后经纬度返回到地图会提示地图某方法不存在

1:在html中增加事件
 <el-amap ref="skyeye_map"
               vid="skyeye_amapDemo"
               id="skyeye_amapDemo"
               :events="mapEvents"
               :amap-manager="amapManager"
              >
               </el-amap>
               
               
    2:data中 
      mapEvents: {
        init (o) {
          lazyAMapApiLoaderInstance.load().then(() => {
            o.setMapStyle("amap://styles/grey"); //自定义的高德地图的样式,我选的是马卡龙
            $this.hasDom = true
          })
        },
      },
      在watch中监听hasDom 如果值返回了 再次把经纬度的数据放回到地图中

创建多边形的电子围栏

效果图

功能点:

用户随意点击任意坐标,进行多边形的绘画,也可拖动点改变多边形的位置

1:.vue文件中引入vue-amap

<template>
  <div class="amap-page-container">
    <el-amap vid="amapDemo"
             ref="map"
             :zoom="zoom"

      <el-amap-polygon v-for="(polygon, index) in polygons"
                       :vid="'ploy'+index"

### 功能点:
点击地图用户获取某一段的经纬度,使这段轨迹动起来(播放时间为一分钟)
