document.addEventListener("keydown", function(e) {
if (e.keyCode == 13) {
toggleFullScreen();
}
}, false);
function toggleFullScreen() {
if (!document.fullscreenElement) {
document.documentElement.requestFullscreen();
} else {
if (document.exitFullscreen) {
document.exitFullscreen();
}
}
}
- document下没有requestFullscreen
- requestFullscreen方法只能由用户触发，比如：在onload事件中不能触发、Vue的mounted内不能触发
