Ниже прикреплены исходники расширения для Chrome - учет закрытых вкладок. Суть в том, что при нажатии на иконку высвечиваются имена страниц, которые были закрыты за сеанс. Если мы зайдем в настройки (chrome-extension://emhohdghchmjepmigjojkehidlielknj/options.html), виден чекбокс "Отображать строку поиска и кнопки сверху". Вопрос: не могу найти в, где именно в js файле находится исполняемый код, который сработает по выбору чекбокса Добавлено через 14 минут и 12 секундЯ так понимаю, все решается через options.js: | Код |
