Thanks, in the meantime I’m using the jQuery plugin jquery.are-you-sure but I don’t think it’s supported anymore. Seems to work though.

I integrated it into my site. For those interested, get the plugin from Here then put the following code into functions.php of your child theme or use the code snippets plugin.

// Check if there are unsaved changes and show warning
add_action( 'wpuf_before_form_render', 'wpuf_unsaved_changes' );
function wpuf_unsaved_changes( $form_id ) {
	?>
		<script type="text/javascript" src= "path/to/js/jquery.are-you-sure.js"></script>
		<script>
		jQuery( document ).ready(function($) {
			$('form').areYouSure();
		});
		</script>
	<?php
}

Make sure you use the correct

path/to

in the code above. There may be a more elegant solution but this works for me.
