如何使用Angular2中的组件呈现动态模板

Question

我已经尝试了很多stackoverflow选项,例如动态加载现有组件Angular 2 Final Release.

我想要做的是获取一个带有ajax请求的html页面,并在我的自定义组件中呈现/编译此模板.

我已经发现angular2有两个不赞成使用的组件,我必须使用ComponentFactoryResolver.

在我的旧解决方案中,我可以设置'[innerHtml]'来呈现HTML.现在我需要一个新的解决方案.

谁能帮助我？

page.component.ts

import { Component, ViewChild, ViewContainerRef, ComponentFactory, OnInit, ComponentFactoryResolver } from '@angular/core';
import { ActivatedRoute, Params } from '@angular/router';


@Component({
    selector: "wd-page",
    templateUrl: "/app/page/page.component.html",
    providers: []
})
export class PageComponent implements OnInit {

    // we need the viewcontainer ref, so explicitly define that, or we'll get back
    // an element ref.
    @ViewChild('dynamicChild', { read: ViewContainerRef })
    private target: ViewContainerRef;

    private page = {
        Source: "<div><h2>Hello world</h2><one-of-my-components></one-of-my-components></div>"
    }


    constructor(
        private vcRef: ViewContainerRef,
        private resolver: ComponentFactoryResolver) { }


        ngOnInit() {
            //What code do i need here?
        }
}

<div #dynamicChild></div>

<!-- Old implementation!

    <div *ngIf="!showSource" [innerHTML]="page">
    </div>
-->

来自不同帖子的通用HTML outlete(Angular 2.1.0动态创建子组件,动态)可用于呈现带有自定义指令的模板.

不要忘记导入包含要渲染的所有自定义组件的模块!

export function createComponentFactory(compiler: Compiler, metadata: Component): Promise<ComponentFactory<any>> {
const cmpClass = class DynamicComponent {};
const decoratedCmp = Component(metadata)(cmpClass);

// Import the module with required components here
@NgModule({ imports: [CommonModule, RouterModule, SharedModule], declarations: [decoratedCmp] })
class DynamicHtmlModule { }

return compiler.compileModuleAndAllComponentsAsync(DynamicHtmlModule)
   .then((moduleWithComponentFactory: ModuleWithComponentFactories<any>) => {
    return moduleWithComponentFactory.componentFactories.find(x => x.componentType === decoratedCmp);
  });
}
