How to do error handling when the submit event is fired on the form?

Question

JavaScript

There is a form in which there is an action attribute.

form.work-content__form#workForm(enctype="multipart/form-data" action='/api/works' method='post' )

The form is submitted when the button is clicked.
Here I take the "form" element. and call the submit event on the form. How to handle an error or a positive result in such a case?
document.getElementById("workForm").submit();

Make validation on the client, if everything is good then submit. Get a response from the server success or err and do what you want with it
