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

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);
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
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());
