Try to use this codes in your php file:

function zumra_scripts() {
          wp_register_script( 'remove-prodduct-from-list', get_template_directory_uri() . '/js/remove-product.js', array('jquery'), false, true );

          wp_localize_script( 'remove-prodduct-from-list', 'sfl_ajax', array(
            'ajaxurl'         => admin_url( 'admin-ajax.php' ),
            'user'.           => get_current_user_id(),
            'post_id'         => get_the_ID(),
            'user_product'    => get_the_ID(), // custom function if any
            'response'        => your_custom_function(), // if any
          );

          if ( is_page( 'savelist' ) ) {
             wp_enqueue_script('remove-prodduct-from-list');
          }
}

add_action( 'wp_enqueue_scripts', 'zumra_scripts' );
