Создать то, что показывает пример, на самом деле довольно просто.Вам просто нужно расширить библиотеку пагинации, чтобы приспособиться к этому.Я был в состоянии сделать это.Независимо от того, сколько страниц вы показываете, на нем по-прежнему отображаются первая, последняя, стрелка назад и стрелка вперед.
Если вы хотите, чтобы все 5 страниц отображались с перемоткой вперед и назад, у вас должно быть столькорезультаты, чтобы заполнить эту страницу.Затем вы устанавливаете num_links на то, что вы хотите до и после, если на 3-й странице.Таким образом, это будет 2. Мои изменения, если вы находитесь на 1-й странице, заставляют его отображаться на 4 страницах позже, когда это применимо.Смотрите изображение ниже.Белый это текущая страница.Зеленый - это доступные страницы.
Надеюсь, я все правильно объяснил, и это работает для вас.Дайте мне знать.
