Angular Click Event on Input Example

Angular Click Event on Input is an Angular event binding it triggers when user click or tap any DOM element and it fires a event of (click). Input events in angular can be handled using input and output decorators and in this tutorial we will learn Angular Click Event on Input with Example. In core javascript we use onclick event to handle the click events of elements but in angular it there is different way to handle the input events like for Click event we use @output decorator to input element and to handle the event of click we use (click) attribute.

Angular is most popular frontend framework and it has its on guidelines to handle events, forms, rendering etc. In this example we will implement a Simple click Event and then we will handle it in typescript component file.

this example of (click) in angular will work in all angular version including angular 2, angular 6, angular 7, angular 8, angular 9, angular 10, angular 11, angular 12, angular 13 and angular 14 application.

Simplest way to use click is as follow

<button (click)="handleClick($event)" 
    type="button"     
>Submit</button> 

handleClick(event) {
     alert("You just clicked");
}

Here we simply assigned the (click) to button element and then handled the event in component as above.

Let’s take an example of it

Step 1 : Create an angular app

First step is to setup an angular app using below command

ng new example-app

Step 2: Create a Component

Create a component and a method

ng g c hello-world

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-hello-world',
  templateUrl: './hello-world.component.html',
  styleUrls: ['./hello-world.component.css'],
})
export class HelloWorldComponent implements OnInit {
  
  constructor() {
  }
  handleClick(event) {
     alert("You just clicked");
  }
  ngOnInit() {}
}

Here we used to click method to handle the input

Step 3 : Create template and add html

Now, add simple html template with button element

<button (click)="handleClick($event)" 
    type="button"     
>Submit</button>
