Question

I've many input boxes in a div and I need to focus one of them programmatically.

How to do it?

It's something like:

<input type="text" name="txt2" />
<input type="text" name="txt3" />
<input type="text" name="txt4" />
<input type="text" name="txt5" />
<input type="text" name="txt6" />
</div>
<button (click)="selectSample()" />

selectSample() {
    ?????????('txt3').focus();
    console.log('Button pressed, txt3 has been selected');
}

Answer 1

@Component({
  selector: 'my-app',
  template: `
<div>
<input #input type="text" name="txt1" />
<input #input type="text" name="txt2" />
<input #input type="text" name="txt3" />
<input #input type="text" name="txt4" />
<input #input type="text" name="txt5" />
<input #input type="text" name="txt6" />
</div>
<button (click)="selectSample()">click</button>
`
})
export class App {
  @ViewChildren('input') inputs;

  selectSample() {
    // console.debug(this.inputs.toArray().find((e) => {
    //  return e.nativeElement.getAttribute('name') == 'txt3';
    //}).nativeElement.value);

    this.inputs.toArray().find((e) => {
      return e.nativeElement.getAttribute('name') == 'txt3';
    }).nativeElement.focus();

  }
}
