编辑和删除不适用于AngularLeaflet
- 确保安装了Angular Leaflet和Leaflet.draw
- 在组件中导入相关依赖包
import { Map, Control, DomUtil } from 'leaflet'; import { Editable, EditOptions } from 'leaflet-draw';
- 创建EditOptions对象并定义编辑选项：
public editOptions: EditOptions = { featuresLayer: null, edit: { featureGroup: null } };
- 创建地图对象并在其上启用编辑：
this.map = new Map('map', {center: [40, -86], zoom: 4}); this.map.addControl(new Control.Draw({ edit: { featureGroup: Editable(this.map, this.editOptions), poly: {allowIntersection: false} }, draw: { polyline: {guideLayers: [this.routeLayer]}, polygon: {allowIntersection: false}, rectangle: {showArea: true}, circle: {showRadius: true}, marker: {}, circlemarker: {} } }));
- 添加一个编辑图层：
this.editOptions.featuresLayer = L.layerGroup().addTo(this.map);
- 对所需要素进行编辑：
let featureGroup = this.editOptions.edit.featureGroup; featureGroup.addLayer(L.geoJSON(data)); featureGroup.editLayer(L.geoJSON(data).getLayers()[0]);
