How to prevent a page from reloading on a post request

Hi, I am making an web application using NodeJS, pug, client-side JS and css. When someone fills out a form, the page doesn't stop reloading, i tried the following:

const form = document.getElementById("mainForm");
form.addEventListener("submit", (e) => {
e.preventDefault();
});

That stopped the page from reloading, but my server was not getting any info back. Can someone please help? Thanks in advance (NOTE: I do not want to redirect to a new page)

You're partway there. Now that you have caught the submit event and disabled the default handling, send the data to the server as an AJAX request but just don't do anything when it succeeds.

I'd be willing to help if you give it your best "good faith" try and have trouble making it work.

If you haven't done them already, you might want to take the AJAX Basics and Working with the Fetch API courses first.
