Hi guys Thanks for helping
I find code which is I need :
requestFullscreen = () => {
if (!document.fullscreenElement) {
document.documentElement.requestFullscreen();
} else if (document.exitFullscreen) {
document.exitFullscreen();
}
};
then I called this function onClick event on Button. After that I will check when User try to left page (alt+f4, alt+tab .. etc) I will show alert for "Are you sure for left page "
