如何使用JavaScript找到操作系统名称和操作系统版本?
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);
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。
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)'
我开始写一个脚本来读取操作系统和浏览器版本，可以在小提琴上测试。请随意使用和扩展。 断变化: 自2020年9月以来，新的Edge被检测到。所以“Microsoft Edge”是基于Chromium的新版本，旧Edge现在被检测为“Microsoft Legacy Edge”!

路德维希的解决方案太棒了。有几个修复(与操作系统无关，我不能把他的原始帖子作为评论，因为这太长了):
IE 11不再自称为MS IE。 IOS上的Chrome把自己伪装成Safari

js似乎是一个很好的文件库。
使用的例子:

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'
我分叉@路德维希代码和删除swfobject的必要性。
我只是使用swfobject代码来检测flash版本。

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!
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。
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.");
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());
嘿，一个快速的解决方案，你可以考虑下面的库:UAPARSER - https://www.npmjs.com/package/ua-parser-js
例子:
<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:""}
你也可以通过npm安装这个库，然后像这样导入它:
import { UAParser } from 'ua-parser-js';
let parser = new UAParser();
parser.getOS();
这个库是一个基于JS的用户代理字符串解析器(window.navigator. JS)。userAgent是浏览器上的用户代理)，所以你可以使用它获得其他细节，如浏览器，设备，引擎等，它也可以与node js一起工作。
如果你需要输入库:https://www.npmjs.com/package/@types/ua-parser-js
我正在使用这个:)
getPlatform() {
const allPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE', 'Android', 'iPhone', 'iPad', 'iPod'];
return allPlatforms.find(item => item === navigator.platform);
}
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!
User-Agent字符串对于获取平台信息(OS, OS版本，cpu-arch等)不再可靠，因为可以重写它们，甚至浏览器的默认设置也不准确。 在浏览器控制台中尝试"console.log(navigator)"并检查User-Agent字段。
为了解决上述问题，W3有一个新的提议(https://wicg.github.io/ua-client-hints/)，它将允许用户请求关于平台的特定信息。截至2021年5月11日，只有基于铬的浏览器(Chrome、Edge、Opera、Brave……)实现了该规范(该提案仍是非正式的)。
获取平台信息的一种方法是服务器通过向初始响应添加'Accept-CH: Sec-CH-UA-Platform-Version'这样的报头来请求特定的信息，来自客户端的任何后续请求都将包含平台信息报头。欲了解更多信息，请参阅上面的链接。
通过Javascript在客户端获取信息，下面的代码可以使用(复制并粘贴在chrome控制台)。
let platformDetails = await navigator.userAgentData.getHighEntropyValues(["architecture",
"platform", "platformVersion", "model", "bitness", "uaFullVersion"]);
console.log(platformDetails);
https://developer.mozilla.org/en-US/docs/Web/API/NavigatorUAData/platform
console.log (navigator.userAgentData.platform)
例如:macOS, Windows
警告:window.navigator.platform已弃用
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
