因此,当用户在Mac上时,我试图将"关闭"按钮移动到左侧,当用户在PC上时,我试图向右移动"关闭"按钮.现在我通过检查用户代理来做到这一点,但是对于可靠的OS检测来说,它太容易被欺骗了.有没有一种可靠的方法来检测运行浏览器的操作系统是Mac OS X还是Windows?如果没有,什么比用户代理嗅探更好?

该window.navigator.platform时的userAgent字符串改变没有欺骗性质.我在Mac上测试过如果我将userAgent更改为iPhone或Chrome Windows,navigator.platform仍然是MacIntel.
该物业也是只读的
我想出了下表
Mac电脑
Mac68K
Macintosh 68K系统.
MacPPC
Macintosh PowerPC系统.
MacIntel
Macintosh Intel系统.iOS设备
iPhone
苹果手机.
iPod
iPod Touch.
iPad
iPad兼容.
现代mac返回navigator.platform == "MacIntel"
但是为了给出一些"未来证明",不要使用完全匹配,希望它们会改变为类似MacARM
或MacQuantum
将来的东西.
var isMac = navigator.platform.toUpperCase().indexOf('MAC')>=0;

由于大多数操作系统使用右侧的关闭按钮,因此当用户使用MacLike操作系统时,您可以将关闭按钮向左移动,否则如果将其放在最常见的一侧(右侧)则不会出现问题.

就这么简单:
function isMacintosh() {
return navigator.platform.indexOf('Mac') > -1
}
function isWindows() {
return navigator.platform.indexOf('Win') > -1

你可以做有趣的事情,如:

var isPC = !isMacintosh();

补充说明:某些浏览器支持navigator.userAgentData.platform
,这是一个只读属性。
console.log(navigator.userAgentData.platform);

请注意,它Navigator.platform
已被弃用。
正如前面的答案中提到的,navigator.platform 已被弃用。\n我们应该使用 navigator.userAgentData,但它仍然缺乏支持(firefox、safari 在 2022 年不支持它)。
\n请注意,navigator.userAgentData 仅适用于通过 https 的兼容浏览器。
\n这是一个使用 UserAgentData 的脚本,并回退到旧的执行方式。
\nfunction get_platform() {\n // 2022 way of detecting. Note : this userAgentData feature is available only in secure contexts (HTTPS)\n if (typeof navigator.userAgentData !== 'undefined' && navigator.userAgentData != null) {\n return navigator.userAgentData.platform;\n }\n // Deprecated but still works for most of the browser\n if (typeof navigator.platform !== 'undefined') {\n if (typeof navigator.userAgent !== 'undefined' && /android/.test(navigator.userAgent.toLowerCase())) {\n // android device\xe2\x80\x99s navigator.platform is often set as 'linux', so let\xe2\x80\x99s use userAgent for them\n return 'android';\n }\n return navigator.platform;\n }\n return 'unknown';\n}\n\nlet platform = get_platform().toLowerCase();\n\nlet isOSX = /mac/.test(platform); // Mac desktop\nlet isIOS = ['iphone', 'ipad', 'ipod'].indexOf(platform) >= 0; // Mac iOs\nlet isApple = isOSX || isIOS; // Apple device (desktop or iOS)\nlet isWindows = /win/.test(platform); // Windows\nlet isAndroid = /android/.test(platform); // Android\nlet isLinux = /linux/.test(platform); // Linux\n
