To refresh or resize a modal window in Bootstrap once the content has been rendered, you can use the $('#myModal').modal('handleUpdate') method. This method triggers the shown.bs.modal event, which updates the modal’s position and dimensions.
Here is an example of how you can use the handleUpdate method to refresh or resize a modal window:
$('#myModal').modal('handleUpdate');
You can call this method whenever you want to update the modal’s position and dimensions, such as after you have loaded new content into the modal or changed the size of the modal window.
It is worth noting that the handleUpdate method is only available in Bootstrap 4. If you are using an earlier version of Bootstrap, you can use the $('#myModal').modal('handleUpdate') method to achieve a similar effect.
$('#myModal').modal('handleUpdate');
You can also use the $('#myModal').modal('update') method to update the modal’s position and dimensions. This method is available in both Bootstrap 3 and 4.
$('#myModal').modal('update');
Finally, you can also use the $('#myModal').modal('refresh') method to refresh the modal’s content and dimensions. This method is only available in Bootstrap 4.
$('#myModal').modal('refresh');
