Check if user is using IE

Question

I am calling a function like the one below by click on divs with a certain class    Is there a way I can check when starting the function if a user is using Internet Explorer and abort   cancel it if they are using other browsers so that it only runs for IE users   The users here would all be on IE8 or higher versions so I would not need to cover IE7 and lower versions   If I could tell which browser they are using that would be great but is not required   Example function       myClass   on  click   function event           my function

This is how the Angularjs team is doing it  v 1 6 5    var msie     holds major version number for IE  or NaN if UA is not IE      Support  IE 9-11 only        documentMode is an IE-only property    http   msdn microsoft com en-us library ie cc196988 v vs 85  aspx     msie   window document documentMode    Then there are several lines of code scattered throughout using it as a number such as   if  event      input   amp  amp  msie  lt   11  return false    and  if  enabled  amp  amp  msie  lt  8

SpiderCode s solution does not work with IE 11  Here is the best solution that I used henceforth in my code where I need browser detection for particular feature   IE11 no longer reports as MSIE  according to this list of changes  it s intentional to avoid mis-detection   What you can do if you really want to know it s IE is to detect the Trident  string in the user agent if navigator appName returns Netscape  something like  the untested    Thanks to this answer  function isIE       var rv   -1    if  navigator appName     Microsoft Internet Explorer           var ua   navigator userAgent      var re    new RegExp  MSIE   0-9  1     0-9  0           if  re exec ua     null        rv   parseFloat  RegExp  1          else 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          return rv    -1   false  true

Update to SpiderCode s answer to fix issues where the string  MSIE  returns -1 but it matches  Trident   It used to return NAN  but now returns 11 for that version of IE      function msieversion            var ua   window navigator userAgent         var msie   ua indexOf  MSIE            if  msie  gt  -1               return ua substring msie   5  ua indexOf      msie             else if  navigator userAgent match  Trident  rv  11                   return 11           else              return false

If you don t want to use the useragent  you could also just do this for checking if the browser is IE   The commented code actually runs in IE browsers and turns the  false  to  true    var isIE      cc on    false  if isIE         The browser is IE   else        The browser is NOT IE

If all you want to know is if the browser is IE or not  you can do this   var isIE   false  var ua   window navigator userAgent  var old ie   ua indexOf  MSIE     var new ie   ua indexOf  Trident      if   old ie  gt  -1      new ie  gt  -1         isIE   true     if   isIE           IE specific code goes here     Update 1  A better method  I recommend this now  It is still very readable and is far less code     var ua   window navigator userAgent  var isIE    MSIE Trident  test ua    if   isIE         IE specific code goes here     Thanks to JohnnyFun in the comments for the shortened answer     Update 2  Testing for IE in CSS  Firstly  if you can  you should use  supports statements instead of JS for checking if a browser supports a certain CSS feature    element        styles for all browsers        supports  display  grid       element          styles for browsers that support display  grid             Note that IE doesn t support  supports at all and will ignore any styles placed inside an  supports statement    If the issue can t be resolved with  supports then you can do this      JS  var ua   window navigator userAgent  var isIE    MSIE Trident  test ua    if   isIE       document documentElement classList add  ie          CSS      element        styles that apply everywhere        ie  element        styles that only apply in IE         Note  classList is relatively new to JS and I think  out of the IE browsers  it only works in IE11  Possibly also IE10    If you are using SCSS  Sass  in your project  this can be simplified to      SCSS  Sass       element        styles that apply everywhere        ie  amp           styles that only apply in IE            Update 3  Adding Microsoft Edge  not recommended   If you also want to add Microsoft Edge into the list  you can do the following  However I do not recommend it as Edge is a much more competent browser than IE   var ua   window navigator userAgent  var isIE    MSIE Trident Edge    test ua    if   isIE         IE  amp  Edge specific code goes here

Many answers here  and I d like to add my input  IE 11 was being such an ass concerning flexbox  see all its issues and inconsistencies here  that I really needed an easy way to check if a user is using any IE browser  up to and including 11  but excluding Edge  because Edge is actually pretty nice   Based on the answers given here  I wrote a simple function returning a global boolean variable which you can then use down the line  It s very easy to check for IE   var isIE   function         var ua   window navigator userAgent          msie   ua indexOf  MSIE             trident   ua indexOf  Trident          isIE    msie  gt  -1    trident  gt  -1    true   false         if  isIE        alert  I am an Internet Explorer         This way you only have to do the look up once  and you store the result in a variable  rather than having to fetch the result on each function call   As far as I know you don t even have to wait for document ready to execute this code as the user-agent is not related to the DOM
