如何使用JavaScript找到操作系统名称和操作系统版本?


当前回答

如果你列出所有的窗口。Navigator的属性使用

console.log(导航);

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] }

注意,oscpu属性提供了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)'

JavaScript可以访问window.navigator.platform——一个表示浏览器平台的字符串: https://developer.mozilla.org/en-US/docs/Web/API/NavigatorID/platform

使用它来提取您需要(并且可以)的任何细节。请注意,并不能保证客户端实际使用了该平台,因为这可以很容易地以多种方式进行修改。

试一试:

console.log (window.navigator.platform);

您可以在导航器对象中找到操作系统名称和版本,就像其他人回答的那样。跨浏览器查找这些信息的标准位置是导航器。userAgent财产。但是,用户代理字符串因操作系统和浏览器的不同而有很大差异。

因此,我创建了一个脚本来封装这个逻辑,并以一种熟悉的方式(如http://www.whatsmybrowser.org)报告最常见的操作系统和浏览器。

我开源了脚本,并上传到github, https://github.com/keithws/browser-report。拉请求是受欢迎的!

如前所述,导航器。平台已弃用。我们应该使用导航器。但它仍然缺乏支持(firefox, safari在2022年不支持它)。

注意导航器。userAgentData只适用于通过https兼容的浏览器。

下面是一个脚本,它将使用UserAgentData,并返回到旧的操作方式。

function get_platform() {
    // 2022 way of detecting. Note : this userAgentData feature is available only in secure contexts (HTTPS)
    if (typeof navigator.userAgentData !== 'undefined' && navigator.userAgentData != null) {
        return navigator.userAgentData.platform;
    }
    // Deprecated but still works for most of the browser
    if (typeof navigator.platform !== 'undefined') {
        if (typeof navigator.userAgent !== 'undefined' && /android/.test(navigator.userAgent.toLowerCase())) {
            // android device’s navigator.platform is often set as 'linux', so let’s use userAgent for them
            return 'android';
        }
        return navigator.platform;
    }
    return 'unknown';
}

let platform = get_platform();

// examples of use
let isOSX = /mac/.test(platform.toLowerCase()); // Mac desktop
let isIOS = ['iphone', 'ipad', 'ipod'].indexOf(platform.toLowerCase()) !== -1; // Mac iOs
let isApple = isOSX || isIOS; // Apple device (desktop or iOS)
let isWindows = /win/.test(platform.toLowerCase()); // Windows
let isAndroid = /android/.test(platform.toLowerCase()); // Android
let isLinux = /linux/.test(platform.toLowerCase()); // Linux

我创建了一个用于解析User Agent字符串的库,名为Voodoo。但是要注意,不应该用它来代替特征检测。

Voodoo所做的是解析userAgent字符串,该字符串在Navigator对象(window.navigator)中找到。并不是所有浏览器都会传递可靠的userAgent字符串,所以即使这是正常的方式,userAgent也不总是可信的。

你可以使用这个javascript函数来检查用户的操作系统

  function getOS() {
  var userAgent = window.navigator.userAgent,
      platform = window.navigator.platform,
      macosPlatforms = ['Macintosh', 'MacIntel', 'MacPPC', 'Mac68K'],
      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;
}

alert(getOS());
