时间:2022-02-12 13:51:07

Angular 2 Components have templates, but you can also create templates inside of your templates using Angular 2 ViewContainer’s createEmbeddedView for more visual control of how you want to generate elements inside of your Angular 2 templates.

import {Component, ViewChild, ViewContainerRef, ComponentFactoryResolver, ViewChild} from '@angular/core';
import {SimpleService} from "../../serivces/simple.service";
import {WidgetThree} from "../widgets/widget-three.component"; @Component({
moduleId: module.id,
selector: 'home',
templateUrl: 'home.component.html'
})
export class HomeComponent { @ViewChild('container', {
read: ViewContainerRef
}) container;
@ViewChild('template') template; constructor(private resolver: ComponentFactoryResolver, private simpleService: SimpleService) {
} ngAfterContentInit(){
const WidgetFactory = this.resolver.resolveComponentFactory(WidgetThree);
this.container.createComponent(WidgetFactory);
this.container.createComponent(WidgetFactory);
this.container.createComponent(WidgetFactory);
this.container.createComponent(WidgetFactory);
this.container.createComponent(WidgetFactory);
} onClick(){
this.container.createEmbeddedView(
this.template
)
} }
<template #template>
<h3>tempalte title</h3>
<section>tempalte section</section>
<footer>template footer</footer>
</template>
