Typescript is unable to detect the buttons

Currently, I am working on a "simple" program in TypeScript and HTML. My comments are in my native language but they are not providing much information. Despite trying various approaches, I can't seem to get my buttons to function properly.

I am aware that ngOnInit is triggered at the beginning of the website, but I included saveNumbers() there just to monitor the progress of the program over time.

Moreover, the input numbers remain static and do not change.

Component's template:

<body>
  <h1>{{ title }}</h1>

  <div id="grid">
    ...
  </div>
  
  <div id="stevila">
    ...
  </div>

  <div id="grid2">
    ...
  </div>

  <router-outlet></router-outlet>
</body>

Component:

import { Component, OnInit, ViewChild, ElementRef } from '@angular/core';
import { clearInterval } from 'node:timers';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  @ViewChild('inputElement') inputElement!: ElementRef;
  ...

Answer №1

Upon reviewing your ngOnInit function, I observed the following line of code: this.stevila = this.saveNumbers();

The issue here is that saveNumbers() returns the same instance each time it is called. This means that the change detection mechanism will not be able to detect any changes because the array object remains the same. To resolve this, you should modify the function to create a new array, push the data into it, and then return the updated variable.
