Is it possible to use Bootstrap 4 modals as a "block ui" feature to fade the screen dynamically during an AJAX call and display a "wait a minute..." message or sandglasses?
Although modals in the framework can be used for UI blocking functionality, I have not been able to find any official documentation or API samples demonstrating how to do so.
My Solution:
I implemented this code on every page that required "block UI" functionality, which was actually added to the root template:
<div class="modal " id="blockAppliactionDialog" tabindex="-1" role="status" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content" style="background-color: transparent; border-width:0;">
<div class="container pt-4 px-5" style="color:white; font-size:large">
<h3>Wait a moment..</h3>
</div>
</div>
</div>
</div>
Subsequently, I activated it using JavaScript:
this.$('#blockAppliactionDialog').modal({
backdrop: 'static',
keyboard: false
});
