Bootstrap 5 模态不会关闭

Question

All my modal forms are working fine. But here's one I ported from Bootstrap 4 to Bootstrap 5 and it won't close. The Close button (the X at the top of the popup) won't close the modal. And the Cancel button won't close the modal.

I updated data-dismiss to data-bs-dismiss . I don't know what else I'm missing. There are no JavaScript errors.

 $('#open-modal').on('click', function() { var $modal = $('#date-filter-modal'); $modal.show(); });

Can anyone suggest what I might have missed?

Answer 1

I looks like you did not initialize the modal. Remove display: block from the modal and "show" it properly like so:

 let modal = new bootstrap.Modal('#date-filter-modal') modal.show()

Answer 2

Looks like I found the issue.

Under Bootstrap 4, I would display the modal like this:

$modal.modal();

This does nothing under Bootstrap 5, so I changed it to this:

$modal.show();

That works, but I guess it is no longer using the Bootstrap modal logic. It's simply making the form visible. Either way, it prevents the normal dismiss logic from working.

The correct syntax is:

$modal.modal('show');

You can try adding a function for .btn-close .

 let modal = new bootstrap.Modal('#date-filter-modal') modal.hide() $('#open-modal').on('click', function() { var $modal = $('#date-filter-modal'); modal.show(); }); $('.btn-close').on('click', function() { var $modal = $('#date-filter-modal'); modal.hide(); });
