如果您正在使用Electron创建网站或创建桌面应用程序，您可能需要获取客户端使用的操作系统的信息。在这种情况下，你可以使用全局属性window。navigator。 如果您使用console.log(navigator)在控制台中记录属性，您将看到包含浏览器、操作系统等信息的子属性的整个对象。

同样，如果你想创建一个本地NodeJS应用程序也是可以的!只需使用const os = require("os");;调用os模块。然后在控制台中记录常量。你会得到一个完整的对象，但如果你想看到平台的名称，你可以输入console.log(os.platform());，并确保在os后添加一对圆括号。平台作为平台在这里是一个功能!

希望这能有所帮助!

我不能评论@Ian Ippolito的回答(因为如果我有代表的话我会评论的)，但根据他的评论链接，我相当确定你可以找到IOS的Chrome版本。https://developer.chrome.com/multidevice/user-agent?hl=ja列出的UA为:Mozilla/5.0 (iPhone;CPU iPhone OS 10_3像Mac OS X) AppleWebKit/602.1.50 (KHTML，像壁虎)CriOS/56.0.2924.75移动/14E5239e Safari/602.1

所以这应该是可行的:

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.
            }

我还没能测试一下(否则我会改进他的答案)，因为我的iPad在家里，而我在工作，但我想我应该把它放在那里。

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)'

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

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());

使用DetectOS.js。这是一个简单的JS定义，适用于没有依赖关系的流行操作系统和浏览器:

class DetectOS { constructor() { this.browser = this.searchString(this.dataBrowser()) this.version = this.searchVersion(navigator.userAgent) || this.searchVersion(navigator.appVersion) this.OS = this.searchString(this.dataOS()) } searchString(data) { for (let i = 0; i < data.length; i++) { let dataString = data[i].string, dataProp = data[i].prop this.versionSearchString = data[i].versionSearch || data[i].identity if (dataString) { if (dataString.indexOf(data[i].subString) !== -1) { return data[i].identity } } else if (dataProp) { return data[i].identity } } } searchVersion(dataString) { let index = dataString.indexOf(this.versionSearchString) if (index === -1) return return parseFloat(dataString.substring(index+this.versionSearchString.length + 1)) } dataBrowser() { return [ /*************** * Chrome ***************/ { string: navigator.userAgent, subString: "Chrome", identity: "Chrome" }, /*************** * Safari ***************/ { string: navigator.vendor, subString: "Apple", identity: "Safari", versionSearch: "Version" }, /*************** * For Older Opera (12.18-) ***************/ { prop: window.opera, identity: "Opera", versionSearch: "Version" }, /*************** * Internet Explorer 10 ***************/ { string: navigator.userAgent, subString: "MSIE", identity: "IE10", versionSearch: "MSIE" }, /*************** * Internet Explorer 11 ***************/ { string: navigator.userAgent, subString: "Trident", identity: "IE11", versionSearch: "rv" }, /*************** * Edge ***************/ { string: navigator.userAgent, subString: "Edge", identity: "Edge", versionSearch: "Edge" }, /*************** * Firefox ***************/ { string: navigator.userAgent, subString: "Firefox", identity: "Firefox" }, { string: navigator.userAgent, subString: "Gecko", identity: "Mozilla", versionSearch: "rv" }, /*************** * For Older Netscapes (4-) ***************/ { string: navigator.userAgent, subString: "Mozilla", identity: "Netscape", versionSearch: "Mozilla" }, /*************** * For Newer Netscapes (6+) ***************/ { string: navigator.userAgent, subString: "Netscape", identity: "Netscape" }, /*************** * Other Browsers ***************/ { string: navigator.userAgent, subString: "OmniWeb", versionSearch: "OmniWeb/", identity: "OmniWeb" }, { string: navigator.vendor, subString: "iCab", identity: "iCab" }, { string: navigator.vendor, subString: "KDE", identity: "Konqueror" }, { string: navigator.vendor, subString: "Camino", identity: "Camino" } ] } dataOS() { return [ { string: navigator.platform, subString: 'Win', identity: 'Windows' }, { string: navigator.platform, subString: 'Mac', identity: 'macOS' }, { string: navigator.userAgent, subString: 'iPhone', identity: 'iOS' }, { string: navigator.userAgent, subString: 'iPad', identity: 'iOS' }, { string: navigator.userAgent, subString: 'iPod', identity: 'iOS' }, { string: navigator.userAgent, subString: 'Android', identity: 'Android' }, { string: navigator.platform, subString: 'Linux', identity: 'Linux' } ] } } const Detect = new DetectOS() console.log("We know your browser – it's " + Detect.browser + " " + Detect.version); console.log("We know your OS – it's " + Detect.OS); console.log("We know everything about you.");
