Answer

Have a look at this

  1. You need to wrap in a form before you can do submit and/or reset – your form tag cannot be in the head of the page
  2. I preventDefault here to not submit you will have to think of a way to do submit or the user cannot see the result – for examplel another submit button or using AJAX

document.getElementById("feedback").addEventListener("submit", function(e) {
  e.preventDefault(); // stop submission
  const html = [...this.elements]
    .filter(ele => {
      if (ele.type === "text" || ele.type==="email") return true;
      if (ele.type === "checkbox" && ele.checked) return true;
      if (ele.type === "submit" || ele.type === "reset") return false;
    })
    .map(ele => {
      const name = ele.name
      const value = ele.value;
      if (ele.classList.contains("thingslike")) return `<tr class="thingslike"><td>${ele.name}</td><td>&nbsp;</td></tr>`
      else return `<tr><td>${ele.name}</td><td>${ele.value}</td></tr>`
    }).join("");
  document.getElementById("res").innerHTML = `You answered: <br/><table id="answer">
   <tbody>${html}</tbody>
   </table>`;
   const like = document.querySelector("#answer .thingslike");
   if (like) like.insertAdjacentHTML("beforebegin",`<tr><td colspan="2">Things you like:</td></tr>`)
})
