[英]How to call another component function?
import { Router, NavigationExtras } from '@angular/router';
export class HomeComponent OnInit {
price;
constructor(private router: Router) { }
async onSubmit(customerData): Promise<any>{
this.price = customerData.price //price = 2500
}
//This is the function help to send the data to another function
test(){
const navigationExtras: NavigationExtras = {state: {price: this.price }};
this.router.navigate(['price-data'], navigationExtras);//this is going to /price-data component
}
}
<span (click)="test()">Start</span></button>
现在,当我单击按钮时,我想调用homecomponent test() function。 两者都是不是父母或孩子的两个组成部分。 那么它是怎么做的呢?
您能显示包含按钮组件的 HTML 吗?
为此,按钮组件应具有 output 属性
@Output("buttonClicked") buttonClicked = new EventEmitter();
然后父母会像这样连接它:
<app-button>
(buttonClicked)='onButtonClicked()'
</app-button>
在父代码中会有这样的:
onButtonClicked(){
//do something in parent component
}
