如果单击左上角的笔记本徽标，您会看到在Mac OS X上的Safari（我仅对其进行过测试）上，该页面会自动全屏显示，我如何实现此功能？

这将帮助您（将其命名为fs.js）并：

/*global Element */
(function( window, document ) {
    'use strict';

    var keyboardAllowed = typeof Element !== 'undefined' && 'ALLOW_KEYBOARD_INPUT' in Element, // IE6 throws without typeof check

        fn = (function() {
