Getting a browser s name client-side

Question

Is there any object or method that returns data about the browser  client-side  For example  I need to detect if the browser is IE  Interner Explorer   Following is the code snippet  function isInternetExplorer         if navigator appName indexOf  quot Microsoft Internet Explorer quot      -1                return true            return false     Is there a better way

Based on is js you can write a helper file for getting browser name like this-  const Browser       const vendor    navigator  amp  amp  navigator vendor        toLowerCase    const userAgent    navigator  amp  amp  navigator userAgent        toLowerCase     Browser getBrowserName        gt      if isOpera    return  opera      Opera   else if isChrome    return  chrome      Chrome   else if isFirefox    return  firefox      Firefox   else if isSafari    return  safari      Safari   else if isInternetExplorer    return  ie      Internet Explorer        Start Detecting browser helpers functions function isOpera       const isOpera   userAgent match      opera   version opr     d        return isOpera     null     function isChrome       const isChrome    google inc  test vendor    userAgent match     chrome crios     d       null    return isChrome     null     function isFirefox       const isFirefox   userAgent match     firefox fxios     d        return isFirefox     null     function isSafari       const isSafari   userAgent match  version    d     safari      return isSafari     null     function isInternetExplorer       const isInternetExplorer   userAgent match     msie  trident     rv    d        return isInternetExplorer     null       End Detecting browser helpers functions  export default Browser    And just import this file where you need    import Browser from    Browser js    const userBrowserName   Browser getBrowserName      return your browser name                                                     opera   chrome   firefox   safari   ie

It s all about what you really want to do  but in times to come and right now  the best way is avoid browser detection and check for features  like Canvas  Audio  WebSockets  etc through simple javascript calls or in your CSS  for me your best approach is use a tool like ModernizR      Unlike with the traditional   but highly unreliable   method of doing    UA sniffing     which is detecting a browser by its  user-configurable  navigator userAgent property  Modernizr does actual feature detection to reliably discern what the various browsers can and cannot do     If using CSS  you can do this    no-js  glossy   no-cssgradients  glossy       background  url  images glossybutton png        cssgradients  glossy       background-image  linear-gradient top   555   333       as it will load and append all features as a class name in the  lt html gt  element and you will be able to do as you wish in terms of CSS   And you can even load files upon features  for example  load a polyfill js and css if the browser does not have native support  Modernizr load        Presentational polyfills            Logical list of things we would normally need     test   Modernizr fontface  amp  amp  Modernizr canvas  amp  amp  Modernizr cssgradients         Modernizr load loads css and javascript by default     nope     presentational-polyfill js    presentational css             Functional polyfills            This just has to be truthy     test   Modernizr websockets  amp  amp  window JSON         socket-io js and json2 js     nope    functional-polyfills js          You can also give arrays of resources to load      both      app js    extra js         complete   function               Run this after everything in this group has downloaded          and executed  as well everything in all previous groups       myApp init                    Run your analytics after you ve already kicked off all the rest      of your app     post-analytics js        a simple example of requesting features from javascript      http   jsbin com udoyic 1

The browser discloses it in navigator userAgent  If you re using jQuery  you re better off using jQuery browser as  Rab Nawaz said  However  as the API documentation says  it s better to check for feature support if possible  Quoting the documentation      We recommend against using this property  please try to use feature detection instead  see jQuery support   jQuery browser may be moved to a plugin in a future release of jQuery    Here is a code example   function isIE         if  window jQuery            return jQuery browser msie    false        else              adapted from jQuery s source          return navigator userAgent toLowerCase   indexOf  msie    gt   0

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   lt   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   lt br gt                     Full version      fullVersion   lt br gt                     Major version     majorVersion   lt br gt                     navigator appName     navigator appName   lt br gt                     navigator userAgent     navigator userAgent   lt br gt       From the source javascripter net

I found a purely Javascript solution here that seems to work for major browsers for both PC and Mac  I tested it in BrowserStack for both platforms and it works like a dream  The Javascript solution posted in this thread by Jason D Souza is really nice because it gives you a lot of information about the browser  but it has an issue identifying Edge which seems to look like Chrome to it  His code could probably be modified a bit with this solution to make it work for Edge too  Here is the snippet of code I found       var browser    function  agent        switch  true            case agent indexOf  edge    gt  -1  return  edge           case agent indexOf  edg    gt  -1  return  chromium based edge  dev or canary            case agent indexOf  opr    gt  -1  amp  amp    window opr  return  opera           case agent indexOf  chrome    gt  -1  amp  amp    window chrome  return  chrome           case agent indexOf  trident    gt  -1  return  ie           case agent indexOf  firefox    gt  -1  return  firefox           case agent indexOf  safari    gt  -1  return  safari           default  return  other            window navigator userAgent toLowerCase     console log window navigator userAgent toLowerCase       n    browser
