Angular 7 triggers the event on only the initial click

I am facing an unusual problem while trying to implement a file upload feature in my Angular application. The issue is that the event only gets triggered on the first click.

template

<input 
        multiple
        type="file" 
        (change)="onFileSelected($event)"
        id="file"
        class="upload-box__btn__file-input"/>
      <label class="upload-box__btn__file-label" for="file">Upload file from PC</label>

component

onFileSelected(event: Event) {
    console.log(event)
    const file = (event.target as HTMLInputElement).files[0];
    // if (file.length >= 1) {
    //   this.fileToUpload = file;
    // }
  }

Answer №1

It seems like the problem lies in attaching a change event to the input type file, which will only trigger if a new file is selected.
