Portfolio Grid Pagination goes to top of page

Dear support,
i tried this solution to avoid the scroll to top, when clicking the next page button. But it does not work. Is there any other solution which works?
Thanks and Regards

//avoid scroll to top when clickin next page

function add_custom_script(){
?>
<script type="text/javascript">
(function($){
function b(id) {
		$('.pagination .inactive').click(function(e) {
			e.preventDefault();

			var section = $(id),
				link = $(this).attr('href'),
				anchor = $(section ).attr('id');

				if(!section.length) return;

				var link = link + '#' + anchor;
				window.location.href = link;
		});
	}
        
        $(document).ready( function() {
            b('#referenzen');
        });
})(jQuery);
</script>
