我正在尝试构建一个动态附加另一个组件的组件.这里的例子是我的父类:

import { Component, ComponentRef, ViewChild, ViewContainerRef, ComponentFactoryResolver } from '@angular/core';

@Component({
    templateUrl: './app/sample-component.component.html',
    selector: 'sample-component'
})
export class SampleComponent {

    @ViewChild('dynamicContent', { read: ViewContainerRef })
    protected dynamicComponentTarget: ViewContainerRef;
    private currentComponent: ComponentRef<any>;
    private selectedValue: any;

    constructor(private componentResolver: ComponentFactoryResolver) {

    }

    private appendComponent(componentType: any) {
        var factory = this.componentResolver.resolveComponentFactory(componentType);
        this.currentComponent = this.dynamicComponentTarget.createComponent(factory);
    }
}

sample-component.component.html:

<div #dynamicContent></div>

它可以附加一个元素,但我不知道如何动态绑定双向,就像我在静态组件中一样: [(ngModel)]="selectedValue"
