效果如图

我用的是AMapLoader这个地图插件,会省去很多配置的步骤,非常方便
首先下载插件,然后在局部引入

import AMapLoader from "@amap/amap-jsapi-loader";

然后在methods里面使用

  // 打开地图弹窗mapShow() {this.innerVisible = true;this.$nextTick(() => {this.initMap();});},// 初始化高德地图initMap() {AMapLoader.load({key: "你的key", //key值是key值 和安全密钥不同version: "2.0", // 指定要加载的 JSAPI 的版本，缺省时默认为 1.4.15plugins: ["AMap.GeoJSON", "AMap.MarkerClusterer", "AMap.MouseTool"], // 需要使用的的插件列表,用到的再次注册，如比例尺'AMap.Scale'等}).then((AMap) => {// 初始化地图this.map = new AMap.Map("DMAMap", {viewMode: "3D", // 是否为3D地图模式zoom: 13, // 初始化地图级别center: [120.987239, 31.391653], //中心点坐标resizeEnable: true,});this.map.setMapStyle("amap://styles/darkblue");this.drawPolygon();});},// 绘制多边形drawPolygon() {let mouseTool = new AMap.MouseTool(this.map);mouseTool.polygon({strokeColor: "#FF33FF",strokeOpacity: 1,strokeWeight: 6,strokeOpacity: 0.2,fillColor: "#1791fc",fillOpacity: 0.4,// 线样式还支持 'dashed'strokeStyle: "solid",// strokeStyle是dashed时有效// strokeDasharray: [30,10],});mouseTool.on("draw", (event) => {// event.obj 为绘制出来的覆盖物对象let path = event.obj.getPath(); // 获取多边形的路径let str = "";let pathArr = [];for (let i = 0; i < path.length; i++) {pathArr.push([path[i].getLng(), path[i].getLat()]);str += path[i].getLng() + "," + path[i].getLat() + " ";}this.geometryArr = pathArr; // 这个就是绘制的点的坐标数组this.addForm.latlng = str;  // 转换为字符串});},// 回显多边形getwPolygon() {let paths = this.addForm.latlng.split(" ");let pathsArr = paths.filter((item) => item).map((item) => item.split(",").map((i) => Number(i)));let polygon = new AMap.Polygon({path: pathsArr,strokeColor: "#FF33FF",strokeWeight: 6,strokeOpacity: 0.2,fillOpacity: 0.4,fillColor: "#1791fc",zIndex: 50,strokeStyle: "solid",});this.map.add(polygon);// 缩放地图到合适的视野级别this.map.setFitView([polygon]);let polyEditor = new AMap.PolyEditor(this.map, polygon);polyEditor.open(); // 开启编辑矢量图形功能polyEditor.on("addnode", (event) => {let path = event.target.getPath();this.filterPath(path); // 处理多边形的经纬度});polyEditor.on("adjust", (event) => {let path = event.target.getPath();this.filterPath(path); // 处理多边形的经纬度});polyEditor.on("removenode", (event) => {let path = event.target.getPath();this.filterPath(path); // 处理多边形的经纬度});polyEditor.on("end", (event) => {let path = event.target.getPath();this.filterPath(path); // 处理多边形的经纬度});},
