[Chrome]点击页面元素后全屏

        function isFullScreen() {
            return (document.fullScreenElement && document.fullScreenElement !== null)
                 || document.mozFullScreen
                 || document.webkitIsFullScreen;
        }


        function requestFullScreen(element) {
            if (element.requestFullscreen)
                element.requestFullscreen();
            else if (element.msRequestFullscreen)
                element.msRequestFullscreen();
            else if (element.mozRequestFullScreen)
                element.mozRequestFullScreen();
            else if (element.webkitRequestFullscreen)
                element.webkitRequestFullscreen();
        }

        function cancelFullScreen() {
            if (document.exitFullscreen)
                document.exitFullscreen();
            else if (document.msExitFullscreen)
                document.msExitFullscreen();
            else if (document.mozCancelFullScreen)
                document.mozCancelFullScreen();
            else if (document.webkitExitFullscreen)
                document.webkitExitFullscreen();
        }

        function toggleFullScreen(element) {
            requestFullScreen(element || document.documentElement);
            cancelFullScreen();
        }

        $(document).ready(function () {
            $("#fullScreen").click(function () {
                toggleFullScreen(document.body);
            });

            $("#fullScreen").click();
        });

或者对桌面快捷方式加上命令 --kiosk （不能按 F11 退出全屏）
