Включение технологии JavaScript в браузере Opera
Достаточно большое количество ресурсов в интернете с помощью технологии JavaScript воспроизводят видео и подгружают данные. Поэтому актуальным остается вопрос, как запустить данную функцию в различных браузерах. Рассмотрим, как её включить в веб-обозревателе Opera.
Активация JavaScript в Opera
Активировать JavaScript можно как глобально для всех сайтов, так и только для тех из них, которым вы больше всего доверяете. Рассмотрим алгоритм действий для обоих этих вариантов.
Вариант 1: Глобальная активация
Для начала рассмотрим, как включить JavaScript в браузере Opera для всех веб-ресурсов без исключения.
-
Чтобы активировать описываемую технологию, необходимо перейти в настройки браузера. Для этого кликните по логотипу Оперы в левом верхнем углу. В открывшемся меню выберите пункт «Настройки» либо просто примените сочетание горячих клавиш Alt+P.
Вариант 2: Включение для отдельных сайтов
Описываемую технологию можно также активировать в Opera только для отдельных, доверенных ресурсов в интернете.
- Для начала необходимо перейти в окно настроек JavaScript, действуя по тому алгоритму, который описан в предыдущем способе по пункт 5 включительно. Далее, оставив переключатель напротив параметра «Разрешено» в деактивированном состоянии, щелкните по кнопке «Добавить» напротив параметра «Разрешить».
- Откроется диалоговое окошко «Добавить сайт». В его единственном поле впишите доменное имя веб-ресурса, для которого вы желаете включить описываемую функцию.
- Затем нажмите кнопку «Добавить».
- После этого указанный домен отобразится в окне настроек JavaScript в блоке «Разрешить». Теперь на этом сайте функция будет активирована. Таким же образом при необходимости можно добавить и другие веб-ресурсы в исключения.
Как видим, с помощью внутренних настроек браузера Opera имеется возможность включить технологию JavaScript как для всех сайтов без исключения, так и так и только для отдельных, доверенных веб-ресурсов.
