Нумерованная постраничная навигация Блогспот, Blogger

Пост (в основном) для пользователей:

Blogger, Блоггер (Blogspot, Блогспот)

Постепенно выполняю заявки читателей. Речь сегодня пойдет о нумерованной постраничной навигации для Блогспот, Blogger.

Вот так она выглядит

Признаюсь честно, было нелегко оформить код одним блоком, что бы без "ковыряний" в шаблоне и других "телодвижений" можно было внедрить виджет одним действием. Однако получилось и теперь вы можете в  Дизайн - Добавить гаджет - HTML/JavaScript, добавить следующий код:

Можно изменить следующие параметры:

var displayPageNum=2 - количество страниц, которые будут показаны на виджете.

var pageCount=4- количество сообщений на одной странице.
