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

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);
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 XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',

'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
