Yes, you can add an event listener to listen for a click on the submit button to run the JavaScript. See here for more information on event listeners:

Keep in mind that there is more than one way to submit a form, for example if a user is navigating the form with their keyboard and they hit the Enter key on the button, the form will submit and your JavaScript won't run. So you'll need to account for other event listeners. jQuery has some short-hand syntax, like this:

$(document).ready(function() {
    $('.Sumbit').click(function() {
        alert('Submit button clicked!');
    });
})
