Результат выполнения еще одного «тестового задания». ..И в который раз затрудняюсь с выбором кавычек. Выкладываю коды здесь, вдруг да когда пригодится. Использовался фреймворк Prototype. Сам текст задания, возможно, выложу позже.
Известные проблемы и ограничения в рамках тестового задания
- при добавления большого количества вкладок отсутствуют боковые границы рядов;
- на странице main.html не отслеживается обновление (через F5) страницы child.html
- в IE 6 было замечено вертикальное смещение правой границы динамически созданных вкладок;
- на странице child.html не отслеживается наличие открывающего документа
document.opener (main.html); - скрипт бесполезно проверять инструментами вроде IETester. Как правило, эти инструменты не отслеживают
document.opener; - отключена возможность удаления активной вкладки с помощью CSS, отсутствует контроль этого процесса средствами javascript.
