            }
        });

is it possible to generate url from js

Answer 1

it is possible to transfer url from php to js through registerScript . And then in js to replace the necessary parts.
PHP:

$js = 'var myUrl = "' . Yii::app()->createUrl('bla/bla/bla', array('id' => 'REPLACE_HERE')) . '";';
Yii::app()->getClientScript()->registerScript('carramba', $js, CClientScript::POS_HEAD )

JS:
var realUrl = myUrl.replace('REPLACE_HERE', id);
