如何使用JavaScript查找操作系统版本？

如果您使用列出所有window.navigator的属性

console.log(navigator);

你会看到这样的东西 

# 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，该oscpu属性为您提供Windows版本。另外，您应该知道：

'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)'

当我在Windows 7的4种主要浏览器上对oscpu进行测试时，oscpu的工作始终不一致。@ Ludwig的解决方案始终如一地工作。

根据wikpedia的说法，en.wikipedia.org / wiki / Windows_NT_6.1 Windows NT 6.1可以是win 7，win 2008服务器或Windows Small Business Server，是否有办法确定哪个是哪个？

不错的解决方案，但是不幸的是，它不适用于Opera Next（en.wikipedia.org/wiki/…）。它被检测为Chrome。为了进行检查，请在用户代理中获取“ OPR”的索引。

@Ludwig的解决方案很棒。几个修复程序（与操作系统无关，并且我不能对他的原始帖子发表评论，因为这太长了）：

  1. IE 11不再将自己标识为MS IE。
  2. IOS上的Chrome伪装成Safari

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

使用它来提取您需要（并且可以）的任何细节。注意，不能保证客户端实际使用该平台，因为可以通过多种方式轻松地对其进行修改。

platform.js似乎是一个不错的文件库。

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'

      windowsPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE'],
      iosPlatforms = ['iPhone', 'iPad', 'iPod'],
      os = null;

  if (macosPlatforms.indexOf(platform) !== -1) {
    os = 'Mac OS';
  } else if (iosPlatforms.indexOf(platform) !== -1) {
    os = 'iOS';
  } else if (windowsPlatforms.indexOf(platform) !== -1) {
    os = 'Windows';
  } else if (/Android/.test(userAgent)) {
    os = 'Android';
  } else if (!os && /Linux/.test(platform)) {
    os = 'Linux';
  }

  return os;
}

navigator正如其他人回答的那样，您可以在对象中找到操作系统名称和版本。可在该navigator.userAgent属性中找到标准的跨浏览器位置。但是，用户代理字符串因操作系统和浏览器而有很大差异。

因此，我创建了一个脚本来封装此逻辑并以熟悉的方式报告最常见的OS和浏览器，例如http://www.whatsmybrowser.org。

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

我创建了一个用于解析用户代理字符串的库，称为Voodoo。但是请注意，不应将其用作特征检测。

Voodoo所做的是，它解析了在导航器对象（window.navigator）中找到的userAgent字符串。并非所有浏览器都传递可靠的userAgent字符串，因此，尽管这是正常的方式，但仍不能始终信任userAgent。

我无法对@Ian Ippolito答案发表评论（因为如果我有代表，我将有评论），但是根据他的评论所链接的文档，我相当确定您可以找到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，例如Mac OS X）AppleWebKit / 602.1.50（KHTML，例如Gecko） CriOS / 56.0.2924.75移动/ 14E5239e Safari / 602.1

所以这应该工作：

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（否则我会改善他的回答），以确保自从iPad在家中而且我在工作时，但我认为应该将它放在那里。

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

例如：

<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，并按以下方式导入它：

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），因此您可以获取它的其他详细信息，例如浏览器，设备，引擎等。它可以与node js一起使用也一样

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