如果您使用

列出所有window.navigator的属性 
console.log(navigator);

你会看到类似这样的东西

# platform = Win32
# appCodeName = Mozilla
# appName = Netscape
# appVersion = 5.0 (Windows; en-US)
# language = en-US
# mimeTypes = [object MimeTypeArray]
# oscpu = Windows NT 5.1
# vendor = Firefox
# vendorSub = 1.0.7
# product = Gecko
# productSub = 20050915
# plugins = [object PluginArray]
# securityPolicy =
# userAgent = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
# cookieEnabled = true
# javaEnabled = function javaEnabled() { [native code] }
# taintEnabled = function taintEnabled() { [native code] }
# preference = function preference() { [native code] }

请注意，oscpu属性为您提供Windows版本。另外，你应该知道：

'Windows 3.11' => 'Win16',
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
'Windows 10' => '(Windows 10.0)|(Windows NT 10.0)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD' => 'OpenBSD',
'Sun OS' => 'SunOS',
'Linux' => '(Linux)|(X11)',
'Mac OS' => '(Mac_PowerPC)|(Macintosh)',
'QNX' => 'QNX',
'BeOS' => 'BeOS',
'OS/2' => 'OS/2',
'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp)|(MSNBot)|(Ask Jeeves/Teoma)|(ia_archiver)'

@Ludwig的解决方案很棒。一些修复（与操作系统没有关系，我不能将其作为对原始帖子的评论，因为这太长了）：

  1. IE 11不再将自己标识为MS IE。
  2. IOS上的Chrome欺骗自己为Safari

    3. 他们是：

JavaScript可以访问window.navigator.platform - 表示浏览器平台的字符串：https://developer.mozilla.org/en/DOM/window.navigator.platform

用它来提取你需要的任何细节（也可以）。请注意，无法保证客户端实际使用该平台，因为这可以通过多种方式轻松修改。

platform.js似乎是一个很好的文件库。

用法示例：

// on IE10 x86 platform preview running in IE7 compatibility mode on Windows 7 64 bit edition
platform.name; // 'IE'
platform.version; // '10.0'
platform.layout; // 'Trident'
platform.os; // 'Windows Server 2008 R2 / 7 x64'
platform.description; // 'IE 10.0 x86 (platform preview; running in IE 7 mode) on Windows Server 2008 R2 / 7 x64'

// or on an iPad
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
platform.os; // 'iOS 5.0'
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'

// or parsing a given UA string
var info = platform.parse('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7.2; en; rv:2.0) Gecko/20100101 Firefox/4.0 Opera 11.52');
info.name; // 'Opera'
info.version; // '11.52'
info.layout; // 'Presto'
info.os; // 'Mac OS X 10.7.2'
info.description; // 'Opera 11.52 (identifying as Firefox 4.0) on Mac OS X 10.7.2'

您可以使用此static功能来检查用户的操作系统

答案 7 :(得分：3)

您可以在navigator对象中找到操作系统名称和版本，正如其他人已经回答的那样。用于查找此信息的标准跨浏览器位置位于navigator.userAgent属性中。但是，用户代理字符串因操作系统和浏览器而异。

因此，我创建了一个脚本来封装这个逻辑，并以熟悉的方式报告最常见的操作系统和浏览器，例如http://www.whatsmybrowser.org。

我开源脚本并将其上传到github，https://github.com/keithws/browser-report。拉请求是受欢迎的！

我已经创建了一个用于解析名为Voodoo的用户代理字符串的库。但要注意，这应该不而不是功能检测。

Voodoo的作用是解析userAgent字符串，该字符串位于Navigator对象（window.navigator）中。并非所有浏览器都传递可靠的userAgent字符串，因此即使这是正常的方式，也不能始终信任userAgent。

我无法评论@Ian Ippolito答案（因为如果我有代表，我会有）但根据他的评论链接的文件，我相当肯定你可以找到IOS的Chrome版本。 https://developer.chrome.com/multidevice/user-agent?hl=ja将UA列为：Mozilla / 5.0（iPhone; CPU iPhone OS 10_3，如Mac OS X）AppleWebKit / 602.1.50（KHTML，如Gecko）CriOS / 56.0.2924.75 Mobile / 14E5239e Safari / 602.1

所以这应该有效：

if ((verOffset = nAgt.indexOf('CriOS')) != -1) {
                //Chrome on iPad spoofing Safari...correct it.
                browser = 'Chrome';
                version = nAgt.substring(verOffset + 6);//should get the criOS ver.
            }

无法测试（否则我会改进他的答案）它确保我的iPad在家里而且我在工作，但我想我会把它放在那里。

为快速解决方案，您可以考虑以下库：UAPARSER-https://www.npmjs.com/package/ua-parser-js

示例：

<script type="text/javascript" src="ua-parser.min.js"></script>
<script type="text/javascript">

var parser = new UAParser();
console.log(parser.getOS()) // will log  {name: "", version:""}

您还可以通过npm安装该库，并按如下所示导入它：

import { UAParser } from 'ua-parser-js';
let parser = new UAParser();
parser.getOS();

该库是一个基于JS的用户代理字符串解析器（window.navigator.userAgent是浏览器上的用户代理），因此您还可以获取其他详细信息，例如浏览器，设备，引擎等，并且可以正常工作以及节点js。

如果您需要输入库：https://www.npmjs.com/package/@types/ua-parser-js
