To detect the operating system on the client machine, one can simply use navigator. appVersion or navigator. userAgent property. The Navigator appVersion property is a read-only property and it returns a string which represents the version information of the browser.
To detect the browser version and browser name, we can use the userAgent in JavaScript.
appName returns the string “Mozilla Firefox”. If it is Edge, navigator. appName returns the string “Microsoft Edge”. Using both objects, we can create an alert box to display what web browser the client is using and this navigator object contain all the information about web browser version, name, and more.
To detect the operating system on running website, one can simply use navigator. appVersion or navigator. userAgent property. The Navigator app Version or userAgent property is a read-only property and it returns a string which represents the operating system information of the browser.
Detecting browser's details:
var nVer = navigator.appVersion;
var nAgt = navigator.userAgent;
var browserName = navigator.appName;
var fullVersion = ''+parseFloat(navigator.appVersion);
var majorVersion = parseInt(navigator.appVersion,10);
var nameOffset,verOffset,ix;
// In Opera, the true version is after "Opera" or after "Version"
if ((verOffset=nAgt.indexOf("Opera"))!=-1) {
browserName = "Opera";
fullVersion = nAgt.substring(verOffset+6);
if ((verOffset=nAgt.indexOf("Version"))!=-1)
fullVersion = nAgt.substring(verOffset+8);
}
// In MSIE, the true version is after "MSIE" in userAgent
else if ((verOffset=nAgt.indexOf("MSIE"))!=-1) {
browserName = "Microsoft Internet Explorer";
fullVersion = nAgt.substring(verOffset+5);

I had some good experiences with Platform.js (demo here), but still, caution is adviced:
I'd like to refer you to the author of WhichBrowser: Everybody lies.
Basically, no browser is being honest. No matter if you use Chrome or IE, they both will tell you that they are "Mozilla Netscape" with Gecko and Safari support. Try it yourself on any of the fiddles flying around in this thread:
hims056's fiddle
Hariharan's fiddle
or any other... Try it with Chrome (which might still succeed), then try it with a recent version of IE, and you will cry. Of course, there are heuristics, to get it all right, but it will be tedious to grasp all the edge cases, and they will very likely not work anymore in a year's time.
Take your code, for example:
<div id="example"></div>
<script type="text/javascript">
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
document.getElementById("example").innerHTML=txt;
</script>
Chrome says:
Browser CodeName: Mozilla
Browser Name: Netscape
Browser Version: 5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36
Cookies Enabled: true
Platform: Win32
User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36
IE says:
Browser CodeName: Mozilla
Browser Name: Netscape
Browser Version: 5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko
Cookies Enabled: true
Platform: Win32
User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko
At least Chrome still has a string that contains "Chrome" with the exact version number. But, for IE you must extrapolate from the things it supports to actually figure it out (who else would boast that they support .NET
or Media Center
:P), and then match it against the rv:
at the very end to get the version number. Of course, even such sophisticated heuristics might very likely fail as soon as IE 12 (or whatever they want to call it) comes out.
There is a library for this purpose: https://github.com/bestiejs/platform.js#readme
Then you can use it this way
// example 1
platform.os; // 'Windows Server 2008 R2 / 7 x64'
// example 2 on an iPad
platform.os; // 'iOS 5.0'
// you can also access on the browser and some other properties
platform.name; // 'Safari'
platform.version; // '5.1'
platform.product; // 'iPad'
platform.manufacturer; // 'Apple'
platform.layout; // 'WebKit'
// or use the description to put all together
platform.description; // 'Safari 5.1 on Apple iPad (iOS 5.0)'
To detect operating system using JavaScript it is better to use navigator.userAgent instead of navigator.appVersion
{
var OSName = "Unknown OS";
if (navigator.userAgent.indexOf("Win") != -1) OSName = "Windows";
if (navigator.userAgent.indexOf("Mac") != -1) OSName = "Macintosh";
if (navigator.userAgent.indexOf("Linux") != -1) OSName = "Linux";
if (navigator.userAgent.indexOf("Android") != -1) OSName = "Android";
if (navigator.userAgent.indexOf("like Mac") != -1) OSName = "iOS";
console.log('Your OS: ' + OSName);
}
PPK's script is THE authority for this kind of things, as @Jalpesh said, this might point you in the right way
var wn = window.navigator,
platform = wn.platform.toString().toLowerCase(),
userAgent = wn.userAgent.toLowerCase(),
storedName;
// ie
if (userAgent.indexOf('msie',0) !== -1) {
browserName = 'ie';
os = 'win';
storedName = userAgent.match(/msie[ ]\d{1}/).toString();
version = storedName.replace(/msie[ ]/,'');
browserOsVersion = browserName + version;
}
Taken from https://github.com/leopic/jquery.detectBrowser.js/blob/sans-jquery/jquery.detectBrowser.sansjQuery.js
Try this one..
// Browser with version Detection
navigator.sayswho= (function(){
var N= navigator.appName, ua= navigator.userAgent, tem;
var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
return M;
})();
var browser_version = navigator.sayswho;
alert("Welcome to " + browser_version);
