我能够使用 Angular ComponentFactoryResolver 让它工作。有一些设置,但是一旦你让它工作,你可以用它来渲染你想要的任何组件(并将它放在你想要的任何地方......包括一个地图框弹出窗口)。
我不确定这是否仍然是执行此操作的“正确”方式(我仍在使用 Angular v5),但它确实有效。
1) 创建动态组件服务(不记得我是从哪里得到这个的……对不起,不管你是谁)
import { Injectable, Injector, ApplicationRef, ComponentFactoryResolver, ComponentRef, Type } from '@angular/core'
@Injectable()
export class DynamicComponentService {
private compRef: ComponentRef<any>;
constructor(private injector: Injector,
private resolver: ComponentFactoryResolver,
private appRef: ApplicationRef) { }
public injectComponent<T>(component: Type<T>, propertySetter?: (type: T) => void): HTMLDivElement {
// Remove the Component if it Already Exists
if (this.compRef) this.compRef.destroy();
// Resolve the Component and Create
const compFactory = this.resolver.resolveComponentFactory(component);
this.compRef = compFactory.create(this.injector);
// Allow a Property Setter to be Passed in (To Set a Model Property, etc)
if (propertySetter)
propertySetter(this.compRef.instance);
// Attach to Application
this.appRef.attachView(this.compRef.hostView);
// Create Wrapper Div and Inject Html
let div = document.createElement('div');
div.appendChild(this.compRef.location.nativeElement);
// Return the Rendered DOM Element
return div;
}
}
2) 使用该服务在 mapbox-gl 弹出窗口中呈现您的自定义组件
import { MyCustomMapboxPopup } from "../app/components/my-custom-mapbox-popup.component"
import { DynamicComponentService } from "../services/dynamic-component";
...
// Inside a map.on("click") or wherever you want to create your popup
// Inject Component and Render Down to HTMLDivElement Object
let popupContent = this.dynamicComponentService.injectComponent(
MyCustomMapboxPopup,
x => x.model = new PopupModel()); // This Is where You can pass
// a Model or other Properties to your Component
new mapboxgl.Popup({ closeOnClick: false })
.setLngLat(...wherever you want the popup to show)
.setDOMContent(popupContent)
.addTo(map);
...
为了避免混淆,自定义弹出组件可能如下所示:
import { Component } from '@angular/core';
@Component({
selector: "custom-mapbox-popup",
templateUrl: "./my-custom-mapbox-popup.component.html"
})
export class MyCustomMapboxPopup {
public model: PopupModel; // Model Property
}
// HTML
<div class="my-custom-popup">
<div *ngIf="model">
<h3>{{this.model.SomeModelProperty}}</h3>
</div>
</div>
