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

其他回答
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。
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。
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!
