Topic: How to autofocus on dynamic modal's form control

galileo premium asked 4 months ago


Expected behavior When opening a modal window containing a form through modalService I want a default form field control (textArea) to be focused, but adding autofocus to textArea tag doesn't work. I've also followed this outdated tutorial and it didn't work:

https://mdbootstrap.com/support/angular/how-to-set-focus-on-input-in-modal/

Actual behavior Nothing happens (form field is not focused)

Resources (screenshots, code snippets etc.)

Please try to add a delay by wrapping your code in setTimeout function. Here is an example code that you can use in your modal component ts file (in this case you need to add #input template variable to the HTML element you want to focus):

  @ViewChild('input', { static: true }) input: ElementRef<HTMLInputElement>;

  constructor(public modalRef: MDBModalRef) {}

  ngOnInit() {
    setTimeout(() => {
      this.input.nativeElement.focus();
    }, 0);
  }
