title: Do SubmitEvents made by a 'submit' event contain the form values?
body: <p>I have an HTML form with multiple inputs and a submit button. I created an eventlistener on the form that listens for 'submit' events. This passes a SubmitEvent into the callback function.</p>
  <p>What I'm wondering, is there a getter or quick object property that can take in the input name (AKA input[name=&quot;XYZ&quot;] and return what the input's value was at the time of submission?</p>
