如何使用JavaScript找到操作系统名称和操作系统版本?
当前回答
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.");

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)'
js似乎是一个很好的文件库。
使用的例子:
// 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'

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。
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);
