here code
function previous(){ new_page = parseint($('#current_page').val()) - 1; //if there item before current active link run function if($('.active_page').prev('.page_link').length==true){ go_to_page(new_page); } } function next(){ new_page = parseint($('#current_page').val()) + 1; //if there item after current active link run function if($('.active_page').next('.page_link').length==true){ go_to_page(new_page); } } function go_to_page(page_num){ //get number of items shown per page var show_per_page = parseint($('#show_per_page').val()); //get element number start slice start_from = page_num * show_per_page; //get element number end slice end_on = start_from + show_per_page; //hide children elements of ayah_image div, specific items , show them $('#ayah_image').children().css('display', 'none').slice(start_from, end_on).css('display', 'block'); /*get page link has longdesc attribute of current page , add active_page class , remove class active page link*/ $('.page_link[longdesc=' + page_num +']').addclass('active_page').siblings('.active_page').removeclass('active_page'); //update current page input field $('#current_page').val(page_num); } $( document ).ready(function() { var show_per_page = 1; //getting amount of elements inside ayah_image div var number_of_items = $('#ayah_image').children().size(); //calculate number of pages going have var number_of_pages = math.ceil(number_of_items/show_per_page); //set value of our hidden input fields $('#current_page').val(0); $('#show_per_page').val(show_per_page); //now when got need navigation let's make ' /* going have in navigation? - link previous page - links specific pages - link next page */ var navigation_html = '<a class="previous_link" href="javascript:previous();">prev</a>'; var current_link = 0; while(number_of_pages > current_link){ navigation_html += '<a class="page_link" style="height:20px; width:30px;" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>'; current_link++; } navigation_html += '<a class="next_link" href="javascript:next();">next</a>'; $('#page_navigation').html(navigation_html); //add active_page class first page link $('#page_navigation .page_link:first').addclass('active_page'); $('#ayah_image').children().css('display', 'none'); //and show first n (show_per_page) elements $('#ayah_image').children().slice(0, show_per_page).css('display', 'block'); });
sounds need couple things:
- update pagination links whenever click nav link.
- only show set number of page links around selected page.
so move page link generating logic function like:
function generatepagelinks(curpage) { var max_page_links = 10; var navigation_html = '<a class="previous_link" href="javascript:previous();">prev</a>'; var current_link = curpage - (max_page_links / 2); while(current_link < (max_page_links / 2) && number_of_pages > current_link){ navigation_html += '<a class="page_link" style="height:20px; width:30px;" href="javascript:go_to_page(' + current_link +')" longdesc="' + current_link +'">'+ (current_link + 1) +'</a>'; current_link++; } navigation_html += '<a class="next_link" href="javascript:next();">next</a>'; return navigation_html; }
and call link go_to_page (and initial call in doc.ready).
untested, sounds reasonable in head ;).
