How to get the PC's OS version in Javascript?
I need to find OS version of a user's device. For the mobile device, I know how it's done and had successfully done that for Ios and Android but I need to find PC's OS versions too.
Suppose I am a user who is using Ubuntu 16.04 then I need to get this from my script but right now I get
"Linux"as OS
I have tried this too. but oscpu key is not provided in the navigator
var user = {}
user.device = {};
function findBrowserDetails() {
user.device = {};
var unknown = '-';
// screen
var screenSize = '';
if (screen.width) {
width = (screen.width) ? screen.width : '';
height = (screen.height) ? screen.height : '';
screenSize += '' + width + " x " + height;
}
console.log("What i get from above link is--", navigator);
// browser
var nVer = navigator.appVersion;
var nAgt = navigator.userAgent || navigator.vendor || window.opera;
var browser = navigator.appName;
var version = '' + parseFloat(navigator.appVersion);
var majorVersion = parseInt(navigator.appVersion, 10);
var nameOffset, verOffset, ix;
// Opera
if ((verOffset = nAgt.indexOf('Opera')) != -1) {
browser = 'Opera';
version = nAgt.substring(verOffset + 6);
if ((verOffset = nAgt.indexOf('Version')) != -1) {
version = nAgt.substring(verOffset + 8);
}
}
// Opera Next
if ((verOffset = nAgt.indexOf('OPR')) != -1) {
browser = 'Opera';
version = nAgt.substring(verOffset + 4);
}
// Edge
else if ((verOffset = nAgt.indexOf('Edge')) != -1) {
browser = 'Microsoft Edge';
version = nAgt.substring(verOffset + 5);
}
// MSIE
else if ((verOffset = nAgt.indexOf('MSIE')) != -1) {
browser = 'Microsoft Internet Explorer';
version = nAgt.substring(verOffset + 5);
}
// Chrome
else if ((verOffset = nAgt.indexOf('Chrome')) != -1) {
browser = 'Chrome';
version = nAgt.substring(verOffset + 7);
}
// Safari
else if ((verOffset = nAgt.indexOf('Safari')) != -1) {
browser = 'Safari';
version = nAgt.substring(verOffset + 7);
if ((verOffset = nAgt.indexOf('Version')) != -1) {
version = nAgt.substring(verOffset + 8);
}
}
// Firefox
else if ((verOffset = nAgt.indexOf('Firefox')) != -1) {
browser = 'Firefox';
version = nAgt.substring(verOffset + 8);
}
// MSIE 11+
else if (nAgt.indexOf('Trident/') != -1) {
browser = 'Microsoft Internet Explorer';
version = nAgt.substring(nAgt.indexOf('rv:') + 3);
}
// Other browsers
else if ((nameOffset = nAgt.lastIndexOf(' ') + 1) < (verOffset = nAgt.lastIndexOf('/'))) {
browser = nAgt.substring(nameOffset, verOffset);
version = nAgt.substring(verOffset + 1);
if (browser.toLowerCase() == browser.toUpperCase()) {
browser = navigator.appName;
}
}
// trim the version string
if ((ix = version.indexOf(';')) != -1) version = version.substring(0, ix);
if ((ix = version.indexOf(' ')) != -1) version = version.substring(0, ix);
if ((ix = version.indexOf(')')) != -1) version = version.substring(0, ix);
majorVersion = parseInt('' + version, 10);
if (isNaN(majorVersion)) {
version = '' + parseFloat(navigator.appVersion);
majorVersion = parseInt(navigator.appVersion, 10);
}

navigator.platform
this will give you the OS name like
UPDATE
var OSName = "Unknown OS";
if (navigator.appVersion.indexOf("Win") != -1) OSName = "Windows";
if (navigator.appVersion.indexOf("Mac") != -1) OSName = "MacOS";
if (navigator.appVersion.indexOf("X11") != -1) OSName = "UNIX";
if (navigator.appVersion.indexOf("Linux") != -1) OSName = "Linux";
console.log('Your OS: ' + OSName);On your system, this script yields the following result:
Your OS: Linux
(To get more detailed OS information, your script should perform a more sophisticated analysis of navigator.appVersion or navigator.userAgent, but the idea would be the same.)
