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!

我正在使用这个:)
getPlatform() {
const allPlatforms = ['Win32', 'Win64', 'Windows', 'WinCE', 'Android', 'iPhone', 'iPad', 'iPod'];
return allPlatforms.find(item => item === navigator.platform);
}
var OSName = "Unknown";
if (window.navigator.userAgent.indexOf("Windows NT 10.0")!= -1) OSName="Windows 10";
if (window.navigator.userAgent.indexOf("Windows NT 6.3") != -1) OSName="Windows 8.1";
if (window.navigator.userAgent.indexOf("Windows NT 6.2") != -1) OSName="Windows 8";
if (window.navigator.userAgent.indexOf("Windows NT 6.1") != -1) OSName="Windows 7";
if (window.navigator.userAgent.indexOf("Windows NT 6.0") != -1) OSName="Windows Vista";
if (window.navigator.userAgent.indexOf("Windows NT 5.1") != -1) OSName="Windows XP";
if (window.navigator.userAgent.indexOf("Windows NT 5.0") != -1) OSName="Windows 2000";
if (window.navigator.userAgent.indexOf("Mac") != -1) OSName="Mac/iOS";
if (window.navigator.userAgent.indexOf("X11") != -1) OSName="UNIX";
if (window.navigator.userAgent.indexOf("Linux") != -1) OSName="Linux";
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
他们是:
