use it like.

    <form method='post' id='userform' action='test2.php'> <tr>
        <td>Trouble Type</td>
        <td>
        <input type='checkbox' name='checkboxvar[]' class="check" value='1'>1<br>
        <input type='checkbox' name='checkboxvar[]' class="check"  value='1'>2<br>
        <input type='checkbox' name='checkboxvar[]'  class="check"  value='1'>3
        </td> </tr> </table> <input type='button' class='buttons'> </form>

<script type="text/javascript">
        $(document).ready(function(){
            $('.buttons').click(function(){
                var checkbox_arr = [];
                $('.check').each(function(){
                    checkbox_arr.push(+$(this).is( ':checked' ));
                });
                console.log(checkbox_arr);
            });
        });
    </script>
