hi,

how to use a javascript pop-up/alert error message in yii captcha, instead of the ordinary

red colored flash message ?




<div id="captchaBox" style="border-bottom: 1px solid #E2E2E2; padding-bottom:10px;">

                            <?php $this->widget('CCaptcha', array('clickableImage' => true)); ?>

                         </div>
