You can try following way to check Browser version        lt  DOCTYPE html gt       lt html gt       lt body gt       lt p gt What is the name s  of your browser  lt  p gt       lt button onclick  myFunction    gt Try it lt  button gt       lt p id  demo  gt  lt  p gt       lt script gt       function myFunction           if  navigator userAgent indexOf  Opera      navigator userAgent indexOf  OPR       -1                  alert  Opera              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  gt  10             alert  IE                 else               alert  unknown                     lt  script gt        lt  body gt       lt  html gt        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   lt  DOCTYPE html gt   lt html gt   lt body gt    lt p gt Click on Try button to check IE Browser version  lt  p gt    lt button onclick  getInternetExplorerVersion    gt Try it lt  button gt    lt p id  demo  gt  lt  p gt    lt script gt  function getInternetExplorerVersion        var ua   window navigator userAgent          var msie   ua indexOf  MSIE             var rv   -1           if  msie  gt  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  gt                  if  navigator appName     Netscape                         var ua   navigator userAgent                      var re   new RegExp  Trident   rv   0-9  1     0-9  0                           if  re exec ua     null                            rv   parseFloat RegExp  1                           alert rv                                                           else                       alert  otherbrowser                                                else                     For  lt  IE11                 alert parseInt ua substring msie   5  ua indexOf      msie                                return false              lt  script gt    lt  body gt   lt  html gt

There is also a less  hacky  method which works for all popular browsers  Google has included a browser-check in their Closure Library  In particular  have a look at goog userAgent and goog userAgent product  In this way  you are also up to date if something changes in the way the browsers present themselves  given that you always run the latest version of the closure compiler

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  Demo  https   jsfiddle net 6spj1059   x000D   x000D     Opera 8 0  var isOpera      window opr  amp  amp    opr addons       window opera    navigator userAgent indexOf   OPR     gt   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   amp  amp  window  safari   pushNotification        Internet Explorer 6-11 var isIE      cc on    false      document documentMode      Edge 20  var isEdge    isIE  amp  amp    window StyleMedia      Chrome 1 - 79 var isChrome     window chrome  amp  amp     window chrome webstore      window chrome runtime       Edge  based on chromium  detection var isEdgeChromium   isChrome  amp  amp   navigator userAgent indexOf  Edg      -1       Blink engine detection var isBlink    isChrome    isOpera   amp  amp    window CSS    var output    Detecting browsers by ducktyping  lt hr gt    output     isFirefox      isFirefox     lt br gt    output     isChrome      isChrome     lt br gt    output     isSafari      isSafari     lt br gt    output     isOpera      isOpera     lt br gt    output     isIE      isIE     lt br gt    output     isEdge      isEdge     lt br gt    output     isEdgeChromium      isEdgeChromium     lt br gt    output     isBlink      isBlink     lt br gt    document body innerHTML   output  x000D   x000D   x000D   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  quot Edg  version  quot  at the end  ex   quot 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 quot    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  quot OPR quot   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  amp  amp  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
