Hi, I need help cuz I have no idea how to use AJAX yet. I would appreciate if someone could show me an example how can I change style of textfield depending on value.




                                                <div class="row">

                                                <?php echo $form->labelEx($model,'number'); ?>

                                                <?php echo $form->textField($model,'number'); ?>

                                                <?php echo $form->error($model,'number'); ?>

                                                </div> 

                                        </td>

                                       

					<td>

                                                <div class="row">

						<?php echo $form->labelEx($model,'price'); ?>

                                                <?php echo $form->textField($model,'price'); ?>

                                                <?php echo $form->error($model,'price'); ?>

                                                </div> 

                                        </td>

Now how can I change background or only font color of price if number >= price ?? Thx in advance ;)
