Angular component fails to display

Below is the code snippet:

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['../assets/css/app.component.css']
})
export class MainVisualComponent {
  main_visual_img:string = "";
  main_visual_desc:string = "";
  main_visual_title:string = "";
  constructor(main_visual_img:string, main_visual_desc:string, main_visual_title:string){
    this.main_visual_img = main_visual_img;
    this.main_visual_desc = main_visual_desc;
    this.main_visual_title = main_visual_title;
  }
}

HTML Code:

<section style="text-align:center">
  <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
    <visual-item></visual-item>
    <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    </a>
    <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    </a>
  </div>
</section>

Answer №1

It turned out to be a simple issue with the component and template binding.

Here is the code snippet that didn't work:

<aria-selected="{{first}}" aria-hidden="{{last}}" aria-controls="SliderItem0{{i+1}}" data-target="#carousel-example-generic" data-slide-to="{{i}}">

After some adjustments, this code now works:

<[attr.aria-selected]="first" [attr.aria-controls]="'SliderItem0'+(i+1)"  data-target="#carousel-example-generic" [attr.data-slide-to]="i">

Answer №2

The identifier for the component is app-root.

To make the change, simply swap out

<visual-item></visual-item>
with
<app-root></app-root>
.

Your updated code will look like this:

<section style="text-align:center">
  <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
    <app-root></app-root>
    <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    </a>
    <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    </a>
  </div>
</section>
