Hi, isn't there a function or a return. When i try this:

    event.preventDefault();
    event.target.classList.add('was-validated');

i always get an undefined. Also when the form is valid or no. Normally i should get something like true or false, or not?

When i add:

         <div class="valid-feedback">
                     Looks good!
         </div>

It is also display:none.

Hi there,

There is a way, but You'll have to code Your own form verification functions and add 'disable' attribute to button conditionally.

Best regards
