How do people show a confirmation popup?

What is the best way to display a confirmation popup when a form is submitted?

I tried the Formit successMessage as an advanced parameter, but that doesn’t seem to do anything, so I’m not sure if I’m doing something wrong with that one.

I also tried setting up some hidden html and triggering a modal popup with javascript, which works on my test page, but I can’t figure out how to tie it to the Formalicious Submit button since it doesn’t expose a custom class or ID for the button.

What do others do about this?

I’d appreciate any help on this too.

I need to either not use redirect or at least redirect to the same page when the form is successfully submitted.

Can’t work out how to get a “Thank You” message on that same page.

Like @ebc I tried successMessage with no joy.

Any help appreciated.
