$(document).keypress(function (e) {
            // 回车键事件  
            if (e.which == 13) {
                $(‘input[type="button"]‘).click();
            }
        });

var fullscreen = function () {
            elem = document.body;
            if (elem.webkitRequestFullScreen) {
                elem.webkitRequestFullScreen();
            } else if (elem.mozRequestFullScreen) {
                elem.mozRequestFullScreen();
            } else if (elem.requestFullScreen) {
                elem.requestFullscreen();
            } else {
                //浏览器不支持全屏API或已被禁用  
            }
        }
