How to call class privat variable inside sockent.on function in angular?

Question

  export class AppComponent {
  title = 'my-app';

  constructor(private notifyService : NotificationService) {}

  ngOnInit() {

    socket.on("laravel_database_chat:test", function(message){
        //I WANT TO CALL NOTIFICATION SERVICE HERE, BUT NOT WORKING
        this.notifyService.showSuccess();

  });

I am trying to call notification service inside socket.io class, but not working.

Answer 1

Change normal function to arrow function to get access to this outside current scope.

ngOnInit() {
    socket.on("laravel_database_chat:test", (message) => {
       this.notifyService.showSuccess();
    });
}
