表格行中已选中复选框的总和？

Question

我正在寻找解决方案，如何动态计算表格行中已选中的复选框，并将已检查的总和传递给另一个单元格。 有我的例子：

<table>
  <thead>
    <tr>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>X</th>
      <th class='ptak'>Counter</th>
      <th class='up'>Time</th>
      <th class='name'>Match</th>
    </tr>
  </thead>
  <tr>
    <td class='a'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='b'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='c'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='d'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='e'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='f'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='g'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='h'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='i'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='j'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td style="text-align: center;">0</td>
    <td class='up'><span class="table-matches__time">02:00</span></td>
    <td class='up'>River Plate Ecuador vs Delfin</td>
  </tr>
  <tr>
    <td class='a'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='b'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='c'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='d'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='e'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='f'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='g'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='h'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='i'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td class='j'>
      <div><input type='checkbox' name='chkboxarray' class='ptaszek'></div>
    </td>
    <td style="text-align: center;">0</td>
    <td class='up'><span class="table-matches__time">05:00</span></td>
    <td class='up'>Warriors vs Home United</td>
  </tr>
</table>

我每行有10个复选框和“计数器”单元格。 不知道如何分隔行中的复选框。

我找到了这个解决方案，但它无法在任何地方工作：

function submitFunction() {
  alert("call countchecks");
  countChecks();
  alert("checkedsizes populated");
  alert("continue with submit");
}

function countChecks() {
  $('.authors-list tr').each(function() {
    var count = 0;
    var hdn = $(this).find('input[name^="checkedsizes"]');
    count = $(this).find(':checkbox:checked').length;
    hdn.val(count);
  });
}

<table class="authors-list">
