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”!

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
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:
(function (window) {
{
/* test cases

'browserInfo result: OS: ' + browserInfo.os +' '+ browserInfo.osVersion + '\n'+
'Browser: ' + browserInfo.browser +' '+ browserInfo.browserVersion + '\n' +

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!
