Опубликовано: 24 Августа, 2022
В этой статье мы реализуем конвертер валют , который просто преобразует валюту в валюту любой другой страны.
Предпосылки:
- Базовый HTML, CSS, JavaScript .
Подход:
- HTML-код реализован для графического интерфейса пользователя для ввода суммы и двух валют.
- Выберите валюту, кнопка « Конвертировать » отобразит конвертированную сумму.
- Кнопка Reset сбрасывает данные.
- Функции и пользовательские методы JavaScript используются для реализации конвертации валюты, например, addEventListener().
- API обмена валюты используется в файле скрипта.
HTML-код: следующий HTML-код реализует графический интерфейс для пользовательских записей, таких как сумма и обе валюты, для которых необходимо выполнить преобразование.
