#javascript #html #pagination
#javascript #HTML #разбивка на страницы
Вопрос:
У меня возникли небольшие проблемы с добавлением некоторой разбивки на страницы на этой странице. Цель состоит в том, чтобы на каждой странице одновременно отображалось только 10 элементов списка. Мне нужно добавить событие к кнопкам, чтобы при нажатии на них отображались соответствующие элементы.
Вот что у меня есть до сих пор в этом codepen http://codepen.io/temovargas/pen/mAqjaA

Ответ №1:
Вы пробовали плагин, такой как DataTables или Jquery.paginate? Я обнаружил, что такого рода элементы домашнего приготовления предоставляют слишком много пользовательских обращений, с которыми придется иметь дело позже. По моему опыту, разработанный плагин будет расширен для обработки крайних случаев и т. Д.
