Is it possible to somehow display the successful upload of a file (file attachment) Contact Form 7?

Question

WordPress

Hello!

Contact form 7 has a dom-event "wpcf7mailsent" and can add a "message sent" dialog. Is it possible to make some kind of indication for the button (color change or loading effect) when a [file] is added?

Answer 1

As far as I remember, we simply attach the file, and it is loaded after submitting the form. Therefore here for a start it is necessary to add such logic.
