this is my code that i wrote contained in the jQuery(doc).prepared…:

jQuery("#slider-wp").slider()

and in my capabilities.php file i wrote this code to name the jQuery library particular to slider():

perform jquery_scripts(){
wp_enqueue_script('jquery');
wp_enqueue_script('jquery-ui-slider'); 
}

add_action( 'admin_enqueue_scripts', 'jquery_scripts');
