Codeigniter使用Bootstrap模态确认删除记录

Question

大家好我想在从我的表中删除记录之前使用bootstrap模式作为确认。

到目前为止我尝试了什么：

  <script type="text/javascript">
      $(function(){
        $(".btn-show-modal").on('click', function(e){
          e.preventDefault(); 
          var id = $(this).attr('id'); 
          var modal_id = "modal"+id; 
          $("#"+modal_id).modal('show'); 
        });
        $(".btn btn-danger").on('click', function(e){
          var id = $(this).attr('id');
          var modal_id = "modal"+id;

          $("#"+modal_id).modal('hide');
        }); 

      });
</script> 

View.php

    <tbody>
    <?php foreach ($sale_list as $u_key){ ?>
    <tr>
    <td><?php echo $u_key->sales_id; ?></td>
    <td><?php $formatted_date = strtotime($u_key->transaction_date);
            echo date('F d, Y H:i:s A', $formatted_date); ?></td></td>
    <td><?php echo $u_key->product_code; ?></td>
    <td><?php echo $u_key->trace_number; ?></td>
    <td><?php echo '0' .$u_key->recipient; ?></td>
    <td><?php echo $u_key->is_paid; ?></td>
    <td><?php echo $u_key->load_balance; ?></td>
    <td><?php echo anchor('customer/view_customer/' . $u_key->customer_id, $u_key->c_fname . ' ' . $u_key->c_lname, array('title' => 'View Customer')); ?></td>
    <td>
        <?php 
            echo anchor('sales/view_sale/' . $u_key->sales_id, '<span class="glyphicon glyphicon-search"></span>', array('title' => 'View Record')  ) . ' | ' .
            anchor('sales/edit_sale/' . $u_key->sales_id, '<span class="glyphicon glyphicon-pencil"></span>', array('title' => 'Update Record') ) . ' | ' .
            anchor('#modal', '<span class="glyphicon glyphicon-remove"></span>', 
                array('title' => 'Delete Record', 'data-toggle' => 'modal', 'class' => 'btn-show-modal', 'id' => $u_key->sales_id ) );

        ?>
    </td>
    </tr>
    <?php }?>
    </tbody>

但这不起作用。我需要将id传递给我的jquery代码，但我不知道该怎么做。
