最全vue的vue-amap使用高德地图插件画多边形范围

一、在vue-cli的框架下的main.js(或者main.ts)中引入高德插件,代码如下:

import Vue from 'vue'
import VueAMap from 'vue-amap'
import ElementUI from 'element-ui'

import App from './App.vue'
import router from './router'
import store from './store'
import './registerServiceWorker'

Vue.use(VueAMap)
Vue.use(ElementUI)

VueAMap.initAMapApiLoader({
  // 高德的key
  key: '你的高德key',
  // 插件集合
  plugin: [
    'AMap.Autocomplete',
    'AMap.PlaceSearch',
    'AMap.Scale',
    'AMap.OverView',
    'AMap.ToolBar',
    'AMap.MapType',
    'AMap.PolyEditor',
    'AMap.CircleEditor',
    'AMap.Geocoder',
    'AMap.Geolocation'
  ],
  // 高德 sdk 版本,默认为 1.4.4
  v: '1.4.10'
})

Vue.config.productionTip = false

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount('#app')

第三种画多边形的效果图:

    注意:1、这种画多边形,开始就需要一个初始的多边形;

       2、所以,输入要画多边形范围的地名,点击搜索,地图会跳转到搜索的地方,同时得到经纬度;

       3、点“范围绘制”时,我再方法里根据第2步的经纬度,初始了一个多边形;

    ****隐藏彩蛋****

  下图的 “请输入经纬度” 可以输入一大组的经纬度,按回车键,也可以画出多边形,在按“范围绘制”也可以更改;(格式如下:)

 

这个格式就是复制的地图上显示的经纬度坐标
106.2246 , 29.59258 106.225064 , 29.593287 106.226137 , 29.593558 106.22692 , 29.593083

 

 

二、第一种画化:使用Geolocation画多边形(效果是在地图点了,才会形成多边形)

 三、第二种画化:使用AMap.MouseTool画多边形(效果是:多边形随鼠标左键点击,多边形直接跟着变化)

三、第三种画化:使用AMap.Polygon和AMap.PolyEditor画多边形(推荐,效果是:https://lbs.amap.com/api/javascript-api/example/overlayers/polygon-draw-and-edit

  注意哦:1、以为这种画多边形,先需要3个点来确定初始的多边形,所以添加了一个功能:搜索 (功能:点击搜索名称的经纬度;);

      2、然后我再 ‘范围绘制’ 的方法里根据“搜索”得来的经纬度,手动的弄了3个经纬度数组。

      3、然后就可以快乐的画图了。(这画图是真的方便,特别是画范围很复杂的)
