一、在vue-cli的框架下的main.js(或者main.ts)中引入高德插件，代碼如下：
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，默認為 1.4.4
v: '1.4.10'
})
Vue.config.productionTip = false
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
第三種畫多邊形的效果圖：
注意：1、這種畫多邊形，開始就需要一個初始的多邊形；
2、所以，輸入要畫多邊形范圍的地名，點擊搜索，地圖會跳轉到搜索的地方，同時得到經緯度；
3、點“范圍繪制”時，我再方法里根據第2步的經緯度，初始了一個多邊形；
****隱藏彩蛋****
下圖的 “請輸入經緯度” 可以輸入一大組的經緯度，按回車鍵，也可以畫出多邊形，在按“范圍繪制”也可以更改；（格式如下：）
這個格式就是復制的地圖上顯示的經緯度坐標
106.2246 , 29.59258 106.225064 , 29.593287 106.226137 , 29.593558 106.22692 , 29.593083
二、第一種畫化：使用Geolocation畫多邊形（效果是在地圖點了，才會形成多邊形）

三、第二種畫化：使用AMap.MouseTool畫多邊形（效果是：多邊形隨滑鼠左鍵點擊，多邊形直接跟著變化）
// 新增 編輯 查看 <template> <div class="point"> <el-header></el-header> <div class="action-bar"> <el-form class="inline-form" :rules="rules" ref="formData" size="small" :model="formData"> <el-form-item label prop="location"> <el-input :disabled="!ifFalg" class="name-input" clearable v-model="formData.location" placeholder="名稱" maxlength="30" ></el-input> </el-form-item> <el-form-item label prop="longitude"> <el-input :disabled="!ifFalg" class="my-input" clearable v-model.number="formData.longitude" placeholder="經度 " ></el-input> </el-form-item> <el-form-item label prop="latitude"> <el-input :disabled="!ifFalg" class="my-input" clearable v-model.number="formData.latitude" placeholder="緯度" ></el-input> </el-form-item> <el-button class="my-button" v-if="ifFalg" type="primary" @click="save" size="small">保存</el-button> <el-button class="my-button" size="small" @click="close">關閉</el-button> </el-form> </div> <div class="map-box"> <div class="map-tool"> <div v-if="ifFalg"> <el-checkbox >地圖上描點</el-checkbox> </div> <div class="longlat"> <ul><li v-for="(item, index) in lnglatpoints" :key="index"> {{item.longitude}} , {{item.latitude}} <i v-if="ifFalg" @click="deletes(item)" ></i> </li> </ul> <br> <div> <span >輸入范圍經緯度：</span> <el-input type="textarea" autosize placeholder="請輸入內容" v-model="lnglatpointsString"> </el-input> </div> <el-button v-if="ifFalg" size="small" @click="clear1" type="primary" class="claer1">確定</el-button> <el-button v-if="ifFalg" size="small" @click="clear" type="primary" class="claer">清除</el-button> </div> </div> <div class="map" id="map"> <el-amap ref="map" bubble :zoom="map.zoom" :center="map.center" :events="mapEvents" id="amap" > <el-amap-polygon :events="plugin.events" :path="path" fillColor="#2b83f9" fillOpacity="0.5" strokeWeight="0" strokeColor="#2b83f9" strokeOpacity="0.5" ></el-amap-polygon> <el-amap-marker v-if="formData.type === 1" :position="map.center" :label="label"></el-amap-marker> </el-amap> </div> <div class="my-tools"> <el-row> <el-button type="primary" v-if="ifFalg" @click="drawPolygon()">滑鼠繪制</el-button> <el-button type="primary" v-if="ifFalg" @click="polygonEditor.close()">結束編輯</el-button> </el-row> </div> </div> </div> </template> <script lang="ts">同上 /** * 繪制多邊形 */ private drawPolygon () { let vm: any = this let map = vm.$refs.map.$$getInstance() map.plugin(['AMap.MouseTool'], function () { var mouseTool = new AMap.MouseTool(map) var drawPolygon = mouseTool.polygon() AMap.event.addListener(mouseTool, 'draw', function (e: any) { e.obj.Je.visible = false let path = e.obj.getPath() vm.drawPolygonsToMap(path) path.forEach((point:any) => { vm.lnglatpoints.push({ latitude: point.lat, longitude: point.lng }) }); // vm.mapDates =path // e.obj.hide() mouseTool.close() }) }) } 同上 } </script> <style lang="scss" scoped> 和上面一樣 </style>
三、第三種畫化：使用AMap.Polygon和AMap.PolyEditor畫多邊形（推薦，效果是：https://lbs.amap.com/api/javascript-api/example/overlayers/polygon-draw-and-edit）
注意哦：1、以為這種畫多邊形，先需要3個點來確定初始的多邊形，所以添加了一個功能：搜索 （功能：點擊搜索名稱的經緯度；）；
2、然后我再 ‘范圍繪制’ 的方法里根據“搜索”得來的經緯度，手動的弄了3個經緯度陣列，
3、然后就可以快樂的畫圖了，（這畫圖是真的方便，特別是畫范圍很復雜的）
