vue+Leaflet.PM插件实现创建和编辑几何图形(点、线、面、圆等)

 

场景
Vue+Leaflet实现加载OSM显示地图：https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/122317394在上面加载显示OSM的基础上，使用Leaflet.pm插件实现在页面上绘制、编辑、剪切、移动几何元素。Leaflet.pm插件
用于创建和编辑几何图层的插件可绘制、编辑、拖动、剪切和捕捉图层支持标记、CircleMarkers、折线、多边形、圆形、矩形、LayerGroups、GeoJSON 和 MultiPolygonsnpm以及文档地址：https://www.npmjs.com/package/leaflet.pm在线演示地址：https://geoman.io/leaflet-geoman/实现
1、首先已经安装并引入了leaflet,其次安装leaflet.pmnpm i leaflet.pm页面中引入import 'leaflet.pm';
import 'leaflet.pm/dist/leaflet.pm.css';
3、地图上添加组件，并设置哪些按钮显示
// 添加绘制工具this.map.pm.setLang("zh");this.map.pm.addControls({position: "topleft",drawPolygon: true, //绘制多边形drawMarker: false, //绘制标记点drawCircleMarker: false, //绘制圆形标记drawPolyline: true, //绘制线条drawRectangle: false, //绘制矩形drawCircle: false, //绘制圆圈editMode: true, //编辑多边形dragMode: true, //拖动多边形cutPolygon: true, //添加⼀个按钮以删除多边形⾥⾯的部分内容removalMode: true, //清除多边形});
4、设置样式、设置事件
// 全局设置绘制样式this.map.pm.setPathOptions({color: "orange",fillColor: "green",fillOpacity: 0.4,});// 或者单独设置绘制样式var options = {// 连接线标记之间的线        templineStyle: {color: "red",},// 提⽰线从最后⼀个标记到⿏标光标的线        hintlineStyle: {color: "red",dashArray: [5, 5],},// 绘制完成的样式        pathOptions: {color: "orange",fillColor: "green",},};// 激活绘制多边形功能-1、单独设置某个模式的样式this.map.pm.enableDraw("Polygon", options);// 启用绘制--多边形功能this.map.pm.enableDraw("Polygon", {snappable: true, //启⽤捕捉到其他绘制图形的顶点snapDistance: 20, //顶点捕捉距离      });// 关闭绘制--注意也可以关闭其他模式的绘制功能this.map.pm.disableDraw("Polygon");// 绘制事件监听this.map.on("pm:drawstart", (e) => {console.log(e, "绘制开始第一个点");});this.map.on("pm:drawend", (e) => {console.log(e, "禁⽌绘制、绘制结束");});this.map.on("pm:create", (e) => {console.log(e, "绘制完成时调⽤");if (e.shape == "Circle") {console.log(e.layer._latlng, e.layer._radius, "绘制坐标");} else {console.log(e.layer._latlngs[0], "绘制坐标");}});this.map.on("pm:globalremovalmodetoggled", (e) => {console.log(e, "清除图层时调用");});
5、其他属性、事件说明等参考官方说明
