This article will provide example of how to call component function on button click event in angular 9/8 application. i want to show you angular 9/8 button click event and call a function example. it's very simple example of click event call function angular 9/8.

If you are new and very beginner with angular 9/8 application and if you are looking for simple example of button click event and call a component function then i will help you using bellow example.

<button (click)="clickFunction()">Click Me</button>
  
<div *ngFor="let post of posts">
   <button (click)="callFunction($event, post)">{{ post.title }}</button>   
</div>

aap.component.ts

import { Component } from '@angular/core';
   
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'appNgContent';
    
  posts = [
    {
      id: 1,
      title: 'Angular Http Post Request Example'
    },
    {
      id: 2,
      title: 'Angular 8 Routing and Nested Routing Tutorial With Example'
    },
    {

  ];
    
  callFunction(event, post){
    console.log(post);
  }
   
  clickFunction() {
    alert("clicked me!");
  }
