Add custom js to add functionality to themes options-page on Wordpress admin-panel?

I 开发者_如何学Chave a theme, which has a options-page. I need to create tabs for it, so I need to include my custom js-file.

I've tried this:

function add_js() {
    echo '<script type="text/javascript" src="'.get_bloginfo('template_url').'/options/js.js'.'"></script>';
}

add_action('wp_head','add_js');

However, this obiviously adds the script to the blog itself, but not the admin-panel. How to include this js-file only in options-page?

Thanks, Martti Laine
