问题描述
在Angular2中,我有一个模板代码,只要用户单击按钮,我都会在其中克隆它们,就像在这里回答
如何在angular2中动态添加一个克隆节点(等效于cloneNode)
In Angular2 I have a template code that I am cloning whenever the user clicks a button, just like answered here How to dynamically add a cloned node in angular2 (equivalent to cloneNode)
我正在尝试将变量传递给它,但是它不起作用。
I am trying to pass a variable to it, but it doesn't work. What's wrong?
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 {}
