                          <input type="text" name="pass">
                          </form>
                      </div>
                          <td>
                          <a class="btn btn-sm btn-danger"  title="Keluar" ></i>
      Keluar</a></td>
                   </tr>
                    <?php 
                    endforeach ;?>
                </tbody>
              </table>

this image when document ready. why not all hidden? when I click one of the button masuk (class btn-primary) then show I want when clik click one of the button masuk (class btn-primary)then show and other still hidden

Change your ids to class.

It should be like the following

<div class='buttonmasuk'>
...
<div class='formmasuk'>

and the script be like the following

$('.formmasuk').hide();
$('.btn-primary').click(function() {
  $(this).closest('.formmasuk').show();
  $(this).closest('.buttonmasuk').hide();
});

Your html id-s should be unique for the page. Try to add unique id-s to the forms because now you are assingning them the same value "formmasuk"

you need to first add Jquery library to your dom add this link in your index.html

         ["http://code.jquery.com/jquery-2.2.4.min.js"
          integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44="
          crossorigin="anonymous"]

and remove the second line of the code datatable from your script then code is working fine and also please end your script tag properly.
