js控制网页全屏显示

// 请求全屏
function enterFullscreen(element) {
    if (element.requestFullscreen) {
        element.requestFullscreen();
    } else if (element.mozRequestFullScreen) { // Firefox
        element.mozRequestFullScreen();
    } else if (element.webkitRequestFullscreen) { // Chrome, Safari and Opera
        element.webkitRequestFullscreen();
    } else if (element.msRequestFullscreen) { // IE/Edge
        element.msRequestFullscreen();
    }
}

// 退出全屏
function exitFullscreen() {
    if (document.exitFullscreen) {
        document.exitFullscreen();
    } else if (document.mozCancelFullScreen) { // Firefox
        document.mozCancelFullScreen();
    } else if (document.webkitExitFullscreen) { // Chrome, Safari and Opera
        document.webkitExitFullscreen();
    } else if (document.msExitFullscreen) { // IE/Edge
        document.msExitFullscreen();
    }
}

// 使用示例
const videoElement = document.getElementById('myVideo');
enterFullscreen(videoElement); // 进入全屏
// exitFullscreen(); // 退出全屏

@media screen and (fullscreen) {
    /* 全屏模式下的样式 */
}
