我正在嘗試使用 javascript（沒有 jquery）在 HTML 中進行個性測驗，但我不知道我的問題出在哪里。我知道我需要把 return false 但我不知道是不知道怎么用好值function count() {  var first = document.querySelector('input[name=first]').value;  var second = document.querySelector('input[name=second]').value;  var dps = 0;  var tank = 0;  var sup = 0;  if (first == 'dps') {    dps++;  }  if (first == 'tank') {    tank++;  }  if (first == 'sup') {    sup++;  }  if (second == 'dps') {    dps++;  }  if (second == 'tank') {    tank++;  }  if (second == 'sup') {    sup++;  }  var count2;  if (dps > tank && dps > sup) {    count2 = "dps";  }  if (tank > dps && tank > sup) {    count2 = "tank";  }  if (sup > dps && sup > tank) {    count2 = "sup";  }  var result = document.getElementById("motek");  result.innerText = count2;}<form id='hello' onsubmit="count()">  <h3>what your favorite food?</h3>  <input type="radio" name="first" value="tank">hghjghj<br>  <input type="radio" name="first" value="dps">hghjfgsfghj<br>  <input type="radio" name="first" value="sup">hghsgdsdqqwj<br>  <h3>what your favoritsfde food?</h3>  <input type="radio" name="second" value="tank">hghfsghj<br>  <input type="radio" name="second" value="dps">hghesfghj<br>  <input type="radio" name="second" value="sup">hghsfdqwj<br>  <input type="submit" value="submit"></form><div id="motek"></div>
