EN

def studentDelete():
    rec_id = request.args(0)
    crud.delete(db.student, rec_id,next=URL('Home','Students_List'))

<div class='btn-group btn-group-justified JpositionA'><a class='btn btn-warning Jview btn-xs opciones'><span class='glyphicon glyphicon-remove'></span></a></div>;

<script>
$(document).on('click', '.opciones', function(e){
      e.preventDefault();
      btn = $(this);
      var tr = $(this).closest('tr');
      var row = tabla.row( tr );
      var datos=row.data();
      var id_record=datos.student.id;

      $('#myModal').modal('show')
     .one('click', '#warning', function(e) {
                     ajax('{{=URL('Tools', 'studentDelete')}}' + '?value=' + id_record);
          });
        });
     });
