任何在Angular 6中自动调用函数的方法，看起来ng-init都不起作用

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

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    this.myFunction();
  }

  myFunction() {
    console.log('Function called automatically');
  }
}

import { Component } from '@angular/core';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent {

  constructor() {
    this.myFunction();
  }

  myFunction() {
    console.log('Function called automatically');
  }
}

import { Component, ViewChild, AfterViewInit } from '@angular/core';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent implements AfterViewInit {

  @ViewChild('myElement') myElement;

  constructor() { }

  ngAfterViewInit() {
    this.myFunction();
  }

  myFunction() {
    console.log('Function called automatically');
  }
}
