Angular2，如何将变量传递给克隆的模板

Question

在 Angular2 中，我有一个模板代码，只要用户单击一个按钮，我就会克隆它，就像这里回答的那样

我正在尝试向它传递一个变量，但它不起作用。怎么了？

import {Component, NgModule, ViewChild, ViewContainerRef} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

@Component({
  selector: 'my-app',
  template: `
    <template #clone let-session>
     <div [id]="session">eps {{session}} ya</div>
    </template>

    <div #container></div>

    <div>
      <button (click)="create()">Hello</button>
    </div>
  `,
})
export class App {
  name:string;

    @ViewChild('clone') clone:any;
    @ViewChild('container', {read:ViewContainerRef}) container:any;

  constructor() {
    this.name = 'Angular2'
  }

  create(){
    let session = 'testing';
        this.container.createEmbeddedView(this.clone, {context: {$implicit: session}});
  }
}

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

Answer 1

create_new_session(s : string) {
    this.container.createEmbeddedView(this.clone, {context: {$implicit: session}});
}

<template #clone let-session>
<section [id]="session"
    [bookmark_draggable_target]="{event_type:'moving_sessions',zone:'title_template'}"
    (drop_here)="onDrop($event)">
</section>
</template>

Answer 2

我已经更新了你的plunkr, basically answer could be found in #8368：

<template #clone let-context="context">
 <div [id]="context.session">eps {{context.session}} ya</div>
</template>

this.container.createEmbeddedView(this.clone, {context: {session: session}});
