        </div>

on selecting test_type i need to send the value of student_track_class_branch as data in test_type via ajax if any one know how to pass this value kindly help me here.

Answer 1

You may specify dropdown id manualy and use it or get it with [[CHtml::activeId()]] if it generated by default. So to get another dropdown value you just need this

'data'=> array( 'std_id' => 'js:$("#'.CHtml::activeId($stmodel,'student_track_class_branch').'").val()'

Answer 2

            <?php echo $form->dropdownlist($model, 'test_type', $this->_test_type,
                                            array(  'empty'=>'--Select--',
                                                    'class'=>'form-control',
                                                        'ajax'=>array('type'=>'POST',
                                                                    'url'=>$this->createUrl('MarkDetails/CreateTestView'),
                                                                    'data'=>'js:$("#StudentTracker_student_track_class_branch").val()',
                                                                    'update'=>'#detail'
                                                                    )
                                                    )
                                                ); ?>

Try this one.
