如何使用JavaScript找到操作系统名称和操作系统版本?
当前回答
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 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
'Windows 10' => '(Windows 10.0)|(Windows NT 10.0)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD' => 'OpenBSD',
'Sun OS' => 'SunOS',
'Linux' => '(Linux)|(X11)',
'Mac OS' => '(Mac_PowerPC)|(Macintosh)',
'QNX' => 'QNX',
'BeOS' => 'BeOS',
'OS/2' => 'OS/2',
'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp)|(MSNBot)|(Ask Jeeves/Teoma)|(ia_archiver)'

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。

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);
}
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。
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 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)|(WOW64)',
'Windows 10' => '(Windows 10.0)|(Windows NT 10.0)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME',
'Open BSD' => 'OpenBSD',
'Sun OS' => 'SunOS',
'Linux' => '(Linux)|(X11)',
'Mac OS' => '(Mac_PowerPC)|(Macintosh)',
'QNX' => 'QNX',
'BeOS' => 'BeOS',
'OS/2' => 'OS/2',
'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp)|(MSNBot)|(Ask Jeeves/Teoma)|(ia_archiver)'
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!
