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(rèn)為 1.4.4 v: ’1.4.10’})Vue.config.productionTip = falsenew Vue({ router, store, render: h => h(App)}).$mount(’#app’)

強(qiáng)烈推薦的第三種畫多邊形的效果圖：

***隱藏的彩蛋哦***

圖里的 “請(qǐng)輸入經(jīng)緯度” ，可以輸入一堆的經(jīng)緯度坐標(biāo)，在按“Enter” ，可以直接形成多邊形；（注意：輸入的格式要和上面顯示的坐標(biāo)全部選中Ctrl+c下來(lái)的格式一樣）

如：

106.628788 , 29.718379106.631187 , 29.718143106.632383 , 29.716281106.628819 , 29.717013

二、第一種畫化：使用Geolocation畫多邊形（效果是在地圖點(diǎn)了，才會(huì)形成多邊形）

三、第二種畫化：使用AMap.MouseTool畫多邊形（效果是：多邊形隨鼠標(biāo)左鍵點(diǎn)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 :rules='rules' ref='formData' size='small' :model='formData'> <el-form-item label prop='location'> <el-input :disabled='!ifFalg' 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' clearable v-model.number='formData.longitude' placeholder='經(jīng)度 ' ></el-input> </el-form-item> <el-form-item label prop='latitude'> <el-input :disabled='!ifFalg' clearable v-model.number='formData.latitude' placeholder='緯度' ></el-input> </el-form-item> <el-button v-if='ifFalg' type='primary' @click='save' size='small'>保存</el-button> <el-button size='small' @click='close'>關(guān)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(diǎn)</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(jīng)緯度：</span> <el-input type='textarea' autosize placeholder='請(qǐng)輸入內(nèi)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 id='map'> <el-amap ref='map' bubble :zoom='map.zoom' :center='map.center' :events='mapEvents' > <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()'>鼠標(biāo)繪制</el-button> <el-button type='primary' v-if='ifFalg' @click='polygonEditor.close()'>結(jié)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(gè)點(diǎn)來(lái)確定初始的多邊形，所以添加了一個(gè)功能：搜索 （功能：點(diǎn)擊搜索名稱的經(jīng)緯度；）；

2、然后我再 ‘范圍繪制’ 的方法里根據(jù)“搜索”得來(lái)的經(jīng)緯度，手動(dòng)的弄了3個(gè)經(jīng)緯度數(shù)組。

3、然后就可以快樂(lè)的畫圖了。（這畫圖是真的方便，特別是畫范圍很復(fù)雜的）。
