Enqueueing scripts if a file exists

I work with wordpress. I would like to auto-enqueue jQuery script CodXXX.js on page id XXX if the relative file exists.

I wrote:

/* Enqueue CondXXX.js on page XXX if file CondXXX.js exists */
function carica_scripts() {
 $pageId = get_the_ID();
 $myBaseURL = get_stylesheet_directory_uri() . '/js/';
 $hookName = 'Cond' . $pageId;
 $condFile = $myBaseURL . $hookName . '.js';
 if (file_exists($condFile)) {
  wp_enqueue_script($hookName, $condFile, array('jquery'));
 }
}
add_action( 'wp_enqueue_scripts', 'carica_scripts' ); 

But I can't manage to have the scripts loaded.

Any idea on how to make it?
