Angular 2 templates have a special let syntax that allows you to define and pass a context when they’re being generated.
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,
{
desc: ‘Good‘
}
)
}
}
We pass in an Object "desc: Good", to the template, in tempalte, we use "let-" keyword to define the variable which we can reference to, and the object will be the ‘context‘ for the template.
<template #template let-desc="desc"> <h3>tempalte {{desc}}</h3> <section>tempalte {{desc}}</section> <footer>template {{desc}}</footer> </template>
