Add nofollow noopener noreferrer to cart button / functions.php / child theme

Hello

Recently i added this function to my child theme’s functions.php file. to add nofollow noopener noreferrer on cart button link

Is it correct to put all three on the same line? (‘nofollow noopener noreferrer’)

It is right like this?

/*  Add nofollow to cart button*/
add_action('wp_footer', 'ava_add_rel_nofollow');
function ava_add_rel_nofollow(){
	?>
	<script type="text/javascript">
		(function($) {
			$('.single_add_to_cart_button').attr('rel', 'nofollow noopener noreferrer');
		})(jQuery);
	</script>
	<?php
}

Thanks
