Событие возникает, когда пользователь нажимает кнопку повышения громкости.
document.addEventListener("volumeupbutton", yourCallbackFunction, false);
Если необходимо переопределить поведение по умолчанию кнопки увличения громкости вы можете зарегистрировать обработчик для события volumeupbutton
.
Приложения обычно должны использовать window.addEventListener
чтобы добавить обработчик события после того как произойдет событие deviceready
.
document.addEventListener("volumeupbutton", onVolumeUpKeyDown, false); function onVolumeUpKeyDown() { // Handle the volume up button }
