如何在cakephp 2.x中的ajax渲染期间传递变量

Question

I want to pass a variable to my ajax rendering function.Something like this

$this->render('tempcomment/'.$id, 'ajax');

and my tempcomment action is

public function tempcomment($id) {
    $commentdata = $this->Post->Comment->findByPostid($pid);
    $this->set('commentdata', $commentdata);
}

but rendering is not working.

See below to start with:

public function tempcomment($id) {
                        //   ^ ------ ...
    $commentdata = $this->Post->Comment->findByPostid($pid);
                                                 //    ^--- this is different!
    $this->set('commentdata', $commentdata);
}
