bootstrap - modal close button not closing - css

Question

I am using bootstrap 4 and I added a modal in my form in laravel project.
Code:
........
<div class="col-md-12">
<div class="row">
<div class="col-md-12">
<button type="button" id="order-btn" class="btn btn-yellow-hub rounded-pill px-30">Procced</button>
</div>
</div>
</div>
</div>
</div>
</div>
<!-- Modal -->
<div class="modal fade" id="confirmOrder" tabindex="-1" role="dialog" aria-labelledby="ModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content modal-content-height">
<div class="modal-header" style="background-color: #D0D0D0">
<h5 class="modal-title">Order Confirmation</h5>
</div>
<div class="modal-body">
<p>Your credit balance will be charge RM{{$rate->cost}} for the invoice. Proceed this order?</p>
<div class="text-center">
<button type="submit" class="btn btn-primary confirm-pay-now ">Pay Now</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
</form>
Basically, the data dismiss for close button is not working and nothing happens when I clicked it. I checked the bootstrap documentation and everything seems to be in order. Some of the solutions I have tried is removing fade class which does nothing. I also tried adding $('#closeButtonID').modal('hide'); but it does not seem to work as well.
How do I fix this?

Answer 1

Make sure If you use CDN then check you your internet connectivity or you use local library then try to go at view page source check that you local library correctly integrate with you webpage..
or I think you need to go through with below reference link try it

Answer 2

Can you try
$('#confirmOrder').modal('hide');
instead of
$('#closeButtonID').modal('hide');
Can you try giving it to the event handler of the button click as
$('. btn-secondary').on('click', function() {
$('#confirmOrder').modal('hide');
})
