I have code like this

<table id='data-table'>
 <thead>
   <tr>
     <th>No</th>
     <th>Name Items</th>
     <th>Qty</th>
     <th>Price</th>
     <th>Action</th>
     <th>Check</th>
   </tr>
 </thead>
 <tbody>
   <php foreach($data as $d) : ?>
     <tr>
     <td><?= $no++ ?></td>
     <td><?= $d['name'] ?></td>
     <td><?= $d['qty'] ?></td>
     <td><?= $d['price'] ?></td>
     <td><button type='button' class='btn' name='up'>up</button></td>
     <td><input type='checkbox'></td>
     </tr>
   <php endforeach ?>
 </tbody>

</table>

I want when click button, that qty update data and checkbox if that check then uncheck, I’m use jquery like this but i don’t know how can i uncheckbox when button click.
Thank you in advance

 $('#data-table tbody').on('click', '.btn[name="up"]', function() {
    const row = $(this).closest('tr')[0];
    const qty = Number(row.cells[2].innerHTML);
    const tqty = qty + 1;
    row.cells[2].innerHTML = tqty;
  });

>Solution :

You should use jQuery all the way or not at all

Also you are missing <tr></tr>

$('#data-table tbody').on('click', '.btn[name="up"]', function() {
  const $row = $(this).closest('tr');
  const $cells = $row.find("td");
  const $qtyCell = $cells.eq(2);
  const qty = +$qtyCell.text()
  $qtyCell.text(qty + 1);
  $cells.eq(5).find("[type=checkbox]").prop("checked",false);
});
