Getting a browser’s name client-side

JavaScript side — you can get browser name like these ways.

if(window.navigator.appName == "") OR if(window.navigator.userAgent == "") 

This is pure JavaScript solution . Which I was required.
I tried on different browsers. It is working fine. Hope it helps.

How do I detect the browser name ?

You can use the navigator.appName and navigator.userAgent properties. The userAgent property is more reliable than appName because, for example, Firefox (and some other browsers) may return the string «Netscape» as the value of navigator.appName for compatibility with Netscape Navigator.

Note, however, that navigator.userAgent may be spoofed, too – that is, clients may substitute virtually any string for their userAgent . Therefore, whatever we deduce from either appName or userAgent should be taken with a grain of salt.

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); >// In Chrome, the true version is after "Chrome" else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) < browserName = "Chrome"; fullVersion = nAgt.substring(verOffset+7); >// In Safari, the true version is after "Safari" or after "Version" else if ((verOffset=nAgt.indexOf("Safari"))!=-1) < browserName = "Safari"; fullVersion = nAgt.substring(verOffset+7); if ((verOffset=nAgt.indexOf("Version"))!=-1) fullVersion = nAgt.substring(verOffset+8); >// In Firefox, the true version is after "Firefox" else if ((verOffset=nAgt.indexOf("Firefox"))!=-1) < browserName = "Firefox"; fullVersion = nAgt.substring(verOffset+8); >// In most other browsers, "name/version" is at the end of userAgent else if ( (nameOffset=nAgt.lastIndexOf(' ')+1) < (verOffset=nAgt.lastIndexOf('/')) ) < browserName = nAgt.substring(nameOffset,verOffset); fullVersion = nAgt.substring(verOffset+1); if (browserName.toLowerCase()==browserName.toUpperCase()) < browserName = navigator.appName; >> // trim the fullVersion string at semicolon/space if present if ((ix=fullVersion.indexOf(";"))!=-1) fullVersion=fullVersion.substring(0,ix); if ((ix=fullVersion.indexOf(" "))!=-1) fullVersion=fullVersion.substring(0,ix); majorVersion = parseInt(''+fullVersion,10); if (isNaN(majorVersion)) < fullVersion = ''+parseFloat(navigator.appVersion); majorVersion = parseInt(navigator.appVersion,10); >document.write('' +'Browser name = '+browserName+'

jQuery.browser and jQuery.browser.version

How can you detect the version of a browser using, To detect the browser version on the client machine, your script can analyze the value of navigator.appVersion or navigator.userAgent. Example console.log (navigator.appVersion) Output This will give the output based on your browser and its version −

What is a RELIABLE way to detect a client’s browser and its version number?

There is no reliable way to perform browser sniffing. My best suggestion would be to take a look at WhichBrowser — the power behing http://html5test.com/

Everybody lies — House M.D.

This is a extremely complicated and almost completely useless browser sniffing library. Useless because you shouldn’t use browser sniffing. So stop right now and go read something about feature detecting instead. I’m serious. Go away. You’ll thank me later.

But why almost completely useless and not completely useless?

Well, there is always an exception to the rule. There is one valid reason to do browser sniffing: to gather intelligence about which browsers are used on your website. My website is html5test.com and I wanted to know which score belongs to which browser. And to do that you need a browser sniffing library.

Why is it extremely complicated?

Because everybody lies. Seriously, there is not a single browser that is completely truthful. Almost all browsers say they are Netscape 5 and almost all WebKit browsers say they are based on Gecko. Even Internet Explorer 11 now no longer claims to be IE at all, but instead an unnamed browser that is like Gecko. And it gets worse. That is why it is complicated.

The main part of this library runs on the server and looks at the headers send by the browser, but it also collects various data from the browser itself. The first thing it looks at is the user-agent header, but there are many more headers that contain clues about the identity of the browser. Once the server finds the identity of the browser, it then looks at the data from the browser itself and check some additional characteristics and tries to determine if the headers where perhaps lying. It then gives you the result.

Notes on install/requirements

How to install it

Place the files in a directory on your server. The server should be able to handle PHP and included is a .htaccess file that instructs the server to also use PHP to parse the detect.js file. This is required and if your server does not support .htaccess files you need to find a way to make your server do the same.

Notes to help you with getting it working on IIS rather than apache

Translate .htaccess Content to IIS web.config

If you get it working on IIS then you may want to post some further notes on how to achieve this.

How to detect Safari, Chrome, IE, Firefox and Opera browser?

Googling for browser reliable detection often results in checking the User agent string. This method is not reliable, because it’s trivial to spoof this value.
I’ve written a method to detect browsers by duck-typing.

Only use the browser detection method if it’s truly necessary, such as showing browser-specific instructions to install an extension. Use feature detection when possible.

// Opera 8.0+ var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0; // Firefox 1.0+ var isFirefox = typeof InstallTrigger !== 'undefined'; // Safari 3.0+ "[object HTMLElementConstructor]" var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) < return p.toString() === "[object SafariRemoteNotification]"; >)(!window['safari'] || (typeof safari !== 'undefined' && window['safari'].pushNotification)); // Internet Explorer 6-11 var isIE = /*@cc_on!@*/false || !!document.documentMode; // Edge 20+ var isEdge = !isIE && !!window.StyleMedia; // Chrome 1 - 79 var isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime); // Edge (based on chromium) detection var isEdgeChromium = isChrome && (navigator.userAgent.indexOf("Edg") != -1); // Blink engine detection var isBlink = (isChrome || isOpera) && !!window.CSS; var output = 'Detecting browsers by ducktyping:
'; output += 'isFirefox: ' + isFirefox + '
'; output += 'isChrome: ' + isChrome + '
'; output += 'isSafari: ' + isSafari + '
'; output += 'isOpera: ' + isOpera + '
'; output += 'isIE: ' + isIE + '
'; output += 'isEdge: ' + isEdge + '
'; output += 'isEdgeChromium: ' + isEdgeChromium + '
'; output += 'isBlink: ' + isBlink + '
'; document.body.innerHTML = output;

Analysis of reliability

The previous method depended on properties of the rendering engine ( -moz-box-sizing and -webkit-transform ) to detect the browser. These prefixes will eventually be dropped, so to make detection even more robust, I switched to browser-specific characteristics:

• Internet Explorer: JScript’s Conditional compilation (up until IE9) and document.documentMode .
• Edge: In Trident and Edge browsers, Microsoft’s implementation exposes the StyleMedia constructor. Excluding Trident leaves us with Edge.
• Edge (based on chromium): The user agent include the value «Edg/[version]» at the end (ex: «Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.16 Safari/537.36 Edg/80.0.361.9 «).
• Firefox: Firefox’s API to install add-ons: InstallTrigger
• Chrome: The global chrome object, containing several properties including a documented chrome.webstore object.
• Update 3 chrome.webstore is deprecated and undefined in recent versions
• Safari: A unique naming pattern in its naming of constructors. This is the least durable method of all listed properties and guess what? In Safari 9.1.3 it was fixed. So we are checking against SafariRemoteNotification , which was introduced after version 7.1, to cover all Safaris from 3.0 and upwards.
• Opera: window.opera has existed for years, but will be dropped when Opera replaces its engine with Blink + V8 (used by Chromium).
• Update 1: Opera 15 has been released, its UA string looks like Chrome, but with the addition of «OPR». In this version the chrome object is defined (but chrome.webstore isn’t). Since Opera tries hard to clone Chrome, I use user agent sniffing for this purpose.
• Update 2: !!window.opr && opr.addons can be used to detect Opera 20+ (evergreen).
• Blink: CSS.supports() was introduced in Blink once Google switched on Chrome 28. It’s of course, the same Blink used in Opera.

Successfully tested in:

• Firefox 0.8 — 61
• Chrome 1.0 — 71
• Opera 8.0 — 34
• Safari 3.0 — 10
• IE 6 — 11
• Edge — 20-42
• Edge Dev — 80.0.361.9

Updated in November 2016 to include detection of Safari browsers from 9.1.3 and upwards

Updated in August 2018 to update the latest successful tests on chrome, firefox IE and edge.

Updated in January 2019 to fix chrome detection (because of the window.chrome.webstore deprecation) and include the latest successful tests on chrome.

Updated in December 2019 to add Edge based on Chromium detection (based on the @Nimesh comment).

You can try following way to check Browser version.

    
What is the name(s) of your browser?
 Try it 
function myFunction() < if((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1 ) < alert('Opera'); >else if(navigator.userAgent.indexOf("Edg") != -1 ) < alert('Edge'); >else if(navigator.userAgent.indexOf("Chrome") != -1 ) < alert('Chrome'); >else if(navigator.userAgent.indexOf("Safari") != -1) < alert('Safari'); >else if(navigator.userAgent.indexOf("Firefox") != -1 ) < alert('Firefox'); >else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10 < alert('IE'); >else < alert('unknown'); >>   

And if you need to know only IE Browser version then you can follow below code. This code works well for version IE6 to IE11

   
Click on Try button to check IE Browser version.
 Try it 
0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer, return version number < if (isNaN(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))))) < //For IE 11 >if (navigator.appName == 'Netscape') < var ua = navigator.userAgent; var re = new RegExp("Trident/.*rv:(8[\.0-9])"); if (re.exec(ua) != null) < rv = parseFloat(RegExp.$1); alert(rv); >> else < alert('otherbrowser'); >> else < //For < IE11 alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie)))); >return false; >>   

I know it may be overkill to use a lib for that, but just to enrich the thread, you could check is.js way of doing this:

is.firefox(); is.ie(6); is.not.safari(); 

Browser detection: server side or client side?, Normally you want to detect the browser in the client but you could just as well detect it at the server. Just know that the user agent string can be faked so you can’t depend on it. The only sure fire way is to have the user choose the browser but you could use browser detection to suggest. Here is the client side …
