All of the above answers ignore the fact that you mention you have no window or navigator :-)

Then I openede developer console in IE11

and thats where it says

Object not found and needs to be re-evaluated.

and navigator, window, console, none of them exist and need to be re-evaluated. I've had that in emulation. just close and open the console a few times.

Use Navigator -  The navigator is an object that contains all information about the client machine s browser   navigator appName returns the name of the client machine s browser    x000D   x000D  navigator appName      Microsoft Internet Explorer         navigator userAgent match  Trident      navigator userAgent match  rv 11        typeof   browser      undefined   amp  amp    browser msie     1    alert  Please dont use IE      alert  This is not IE   x000D   lt script src  https   ajax googleapis com ajax libs jquery 2 1 1 jquery min js  gt  lt  script gt  x000D   x000D   x000D

A pretty safe  amp  concise way to detect IE 11 only is if window msCrypto           I m IE11 for sure    or something like this var IE11    window msCrypto   msCrypto is a prefixed version of the window crypto object and only implemented in IE  11  https   developer mozilla org en-US docs Web API Window crypto

Edit 18 Nov 2016  This code also work  for those who prefer another solution   without using ActiveX   var isIE11     window MSInputMethodContext  amp  amp    document documentMode       true on IE11      false on Edge and other IEs browsers    Original Answer  In order to check Ie11    you can use this      tested    or run this     window ActiveXObject   amp  amp   ActiveXObject  in window  I have all VMS of IE             Notice   this wont work for IE11     as you can see here   it returns true       So what can we do     Apparently   they added the machine bit space     ie11      Mozilla 5 0  Windows NT 6 3  WOW64  Trident 7 0   NET4 0E   NET4 0C   NET CLR 3 5 30729   NET CLR 2 0 50727   NET CLR 3 0 30729  rv 11 0  like Gecko    ie12      Mozilla 5 0  Windows NT 6 3  Win64  x64  Trident 7 0   NET4 0E   NET4 0C   NET CLR 3 5 30729   NET CLR 2 0 50727   NET CLR 3 0 30729  rv 11 0  like Gecko    so we can do     x64 x32 ig test window navigator userAgent    this will return true only for ie11

Using this RegExp seems works for IE 10 and IE 11   function isIE        return  Trident   MSIE  test window navigator userAgent       I do not have a IE older than IE 10 to test this

User · Answer

I found IE11 is giving more than one user agent strings in different environments   Instead of relying on MSIE  and other approaches  It s better to rely on Trident version  const isIE11   userAgent   gt  userAgent match  Trident     d          userAgent match  Trident     d       1   gt   7    Hope this helps

I use the following function to detect version 9  10 and 11 of IE   function ieVersion         var ua   window navigator userAgent      if  ua indexOf  Trident 7 0    gt  -1          return 11      else if  ua indexOf  Trident 6 0    gt  -1          return 10      else if  ua indexOf  Trident 5 0    gt  -1          return 9      else         return 0      not IE9  10 or 11
