问题描述
我正在尝试使用传单和其他传单插件实现地图组件.问题是其他插件由于某种原因在 TypeScript 中不起作用.
I'm attempting to implement a map component with leaflet and other leaflet plugins. The issue is other plugins don't work from TypeScript for some reason.
例如,我无法使用leaflet-draw插件编译代码并出现错误:
For example I'm unable to compile code with leaflet-draw plugin and getting the error:
typeof Control"类型不存在Draw"属性
Property 'Draw' does not exist on type 'typeof Control'

mapbox.component.ts
import { DataService } from "../data-service.service";
import { Component, OnInit } from '@angular/core';
import * as $ from 'jquery';
/// <reference types="leaflet" />
/// <reference types="leaflet-draw" />
declare var require: any
@Component({
selector: 'app-mapbox',
templateUrl: './mapbox.component.html',
styleUrls: ['./mapbox.component.css']
})
export class MapboxComponent implements OnInit {
constructor(private dataService: DataService) { }
// helper flags
map: L.Map = null;
aggreagte: boolean = false;
ngOnInit() {
// Prepare map
this.map = L.map('resultmap').setView([51.505, -0.09], 1);
//
L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token={accessToken}', {

maxZoom: 18,

accessToken: '...'
}).addTo(this.map);
var drawnItems = L.featureGroup();
this.map.addLayer(drawnItems);
var control = new L.Control.Draw();

推荐答案
我通过导入leaflet-draw解决了这个问题
I solved the issue by importing leaflet-draw
import 'leaflet-draw';
不知道为什么它没有被 tsconfig 导入,但是它可以工作!
Not sure why it wasn't import by tsconfig, but yay it works!
