Autofocus Input Element on Modal Open Bootstrap 4

Question

I am trying to autofocus input element on bootstrap 4 modal open . I have tried below code from http://getbootstrap.com/docs/4.0/components/modal/ but this is not working.

Can someone help me to give working demo

$('#myModal').on('shown.bs.modal', function () {
  $('#myInput').trigger('focus')
})

Answer 1

Try the snippet below. Perhaps you need $(document).ready()

$(document).ready(function() {
  $('#myModal').on('shown.bs.modal', function() {
    $('#myInput').trigger('focus');
  });
});

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">

</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
