Question

如何在下面的代码片段中计算带有"绿色"值的单选按钮？

<tr id="1">
  <td style="color : blue;"><b>President Staff</b></td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1"  value="green" onClick="green('1')" required></td>

Answer 1

使用 CSS 属性选择器，input[value="green"] ，获取所有带有 .querySelectorAll() 的 .它将生成一个数组，因此您可以读取其length属性。

更具体地说，您也可以将其与[type="radio"]结合使用：

input[type="radio"][value="green"]

更新：

根据要求，要选择仅选中，请使用 CSS :checked

input[value="green"][type="radio"]:checked

console.log(document.querySelectorAll('input[value="green"][type="radio"]:checked').length)

<tr id="1">
  <td style="color : blue;"><b>President Staff</b></td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1"  value="green" onClick="green('1')" required></td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1"  value="red" onClick="red('1')" required></td>
</tr>
<tr id="2">
  <td>Corporate Planning & Program Office</td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan2"  value="green" onClick="green('2')" required></td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan2"  value="red" onClick="red('2')"required></td>
</tr>
<tr id="3">
  <td>Acquisitiom & Aircraft Management</td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan3"  value="green" onClick="green('3')"required></td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan3"  value="red" onClick="red('3')"required></td>
</tr>
<tr id="4">
  <td>Corporate Quality, Safety & Environmentak Management</td>
  <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan4"  value="green" onClick="green('4')"required></td>

Answer 2

使用 Document QuerySelector 属性尝试此操作，如 @wscourge 所述，这将记录选定的绿色和红色无线电

window.addEventListener("load", function() {
  var radioOption = document.querySelectorAll('input[type=radio][name^="jabatan"]');
  radioOption.forEach(function(e) {
    e.addEventListener("click", function() {
      console.clear();
      console.log('Green : ' + document.querySelectorAll('input[type=radio][value="green"]:checked').length + 'nRed : ' + document.querySelectorAll('input[type=radio][value="red"]:checked').length);
    });
  });
});

    <td style="color : blue;"><b>President Staff</b></td>
    <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1" value="green" onClick="green('1')" required></td>
    <td class="text-center" style="padding-left:40px;"><input type="radio" class="form-check-input" name="jabatan1" value="red" onClick="red('1')" required></td>
