ajax pagination

ajax_pagination_.js

var $pagination = $("#demo1 ul");
	$pagination.delegate('.jPag-current', 'click', function() {
		var $$this = $(this);
		$$this.closest('li').addClass('cached');
		$pagination.find("#currentPage").removeAttr('id').wrapInner($('<a>', {'class':'pagenumbers', 'href':'book_data.php?keywords='+keywords}));
		$$this.closest('li').attr('id','currentPage').html( $$this.text() );
		
		$.ajax({
			type	: "GET",
			cache	: false,
			url		: "book_data.php",
			data	: { keywords : keywords, page : $$this.text() },
			success : show_results
		});

		return false;
	});

Need to implement some sort of slicing, to manage page numbers.
