Bootstrap v5 modal show issue

2

I decided to go ahead and update my site to the latest version of Bootstrap, version 5.0 and am having difficulty getting modals to work. Reading the migration guide said nothing about breaking modals and my site worked perfectly before. My code uses javascript/jQuery to fire off the modal after the ajax loads the text. The ajax part still works fine, but it's not firing the modal after it retrieves it. I'm using the latest bootstrap.bundle.min.js.

$( document ).ready(function() {
$('.hourModal').click(function(){
    var obj_id = $(this).data('id');
    $.ajax({
        url: 'ajax-multi.php',
        type: 'POST',
        data: {obj_id: obj_id,role:'some_role'},
        //dataType: 'html',
        success: function(response){ 
            $('.modal-body').html(response);
            //$('#hourModal').modal('show'); //Old way that worked great
            var hourModal = new bootstrap.Modal(document.getElementById('hourModal'));
            hourModal.show(); // New way I tried from the Bootstrap documentation
        }
    });
});
});

        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

The error I get is: Uncaught TypeError: BACKDROP: Option "rootElement" provided type "null" but expected type "element".

Any help is greatly appreciated!

UPDATE: As described below, I had to move bootstrap.min.js to the end of the page, after </body> and leave where I call jquery.min.js at the top in the header. Anyone have any idea why it has to be done this way?

• You are mixing php and JS which is never a good idea. – SuperDJ May 7 at 19:26
