和我的父组件.ts是:
import { Component, ViewChild, AfterViewInit } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements AfterViewInit {
// @ViewChild('test') appgreetcomponentreetComponent;
ngAfterViewInit(): void {
}
constructor() {
}
}
和我想在其中使用ush(or us = ush)的父HTML
<app-greet-component>
<h1 class="head">Hello {{ us }}</h1><br>
<br><button type="button" btnp>Click here {{ us }}</button>
</app-greet-component>
和我的子组件.ts,我将'ush'变量放在名为'us'的公共变量中(但未定义),并将在我的父html中使用它:
import { Component, OnInit, Input, Output, ViewChild, ElementRef } from '@angular/core';
@Component({
selector: 'app-greet-component',
templateUrl: './greet-component.component.html',
styleUrls: ['./greet-component.component.css']
})
export class GreetComponentComponent implements OnInit {
ush:any;
public us = this.ush;
clic(){
console.log(this.us);
}
greet = 'Welcom to our restaurant! We are best in service.';
constructor() { }
ngOnInit() {
}
}
和我由ngModel带到这里的孩子Html,想要在上面的我的父html中使用它:
<div>
your name:
<input type="text" #userName [(ngModel)]="ush">
<ng-content select=".head"></ng-content>
{{ greet }}<br>
<ng-content select="[btnp]"></ng-content>
<br><br><br>
<button type="button" (click)="clic()">click</button>
</div>
请帮助我做到这一点,这意味着我应该添加或删除什么?
