Use the following code in the functions.php file at your theme’s folder
function my_enqueue($hook) {
if ( 'edit.php' == $hook ) {
return;
}
wp_register_script( 'xxx', get_template_directory_uri() . '/includes/js/slider.js', array( 'jquery' ) );
wp_enqueue_script( 'xxx' );
}
add_action( 'admin_enqueue_scripts', 'my_enqueue' );
The admin_enqueue_scripts action hook can also be used to target a specific admin page.
