Event binding is a technique in Angular 8 used to handle the events raised from the DOM like button click, mouse move etc. When the DOM event happens (eg. click, change, keyup, keydown), it calls the specified method in the component.
See an example of event binding. In this example, the playMusic() method from the component will be called when you will click the button:
For example:
In Angular 8, as in other versions of Angular, event binding is a fundamental concept that allows you to respond to user actions, such as button clicks, mouse movements, and keyboard inputs, by executing specific functions or methods in your component. The purpose of event binding is to establish a connection between the user interface (UI) and the component’s logic, enabling the application to respond dynamically to user interactions.
Event binding in Angular uses parentheses ( ) to bind an event from the template to a method or expression in the component class. For example, you might use event binding to handle a button click:
In the corresponding component class:
onButtonClick() {
// Handle the button click logic here
}
}
The purpose of event binding is to enhance the interactivity of your Angular applications, making them more responsive and user-friendly. It allows you to create dynamic and interactive user interfaces by triggering actions in response to user input events
