To detect operating system using JavaScript it is better to use navigator userAgent instead of navigator appVersion    x000D   x000D    x000D    var OSName    Unknown OS   x000D    if  navigator userAgent indexOf  Win      -1  OSName    Windows   x000D    if  navigator userAgent indexOf  Mac      -1  OSName    Macintosh   x000D    if  navigator userAgent indexOf  Linux      -1  OSName    Linux   x000D    if  navigator userAgent indexOf  Android      -1  OSName    Android   x000D    if  navigator userAgent indexOf  like Mac      -1  OSName    iOS   x000D    console log  Your OS      OSName   x000D    x000D   x000D   x000D

I m sad to say  We are sh t out of luck on this one   I d like to refer you to the author of WhichBrowser  Everybody lies   Basically  no browser is being honest  No matter if you use Chrome or IE  they both will tell you that they are  Mozilla Netscape  with Gecko and Safari support  Try it yourself on any of the fiddles flying around in this thread   hims056 s fiddle  Hariharan s fiddle  or any other    Try it with Chrome  which might still succeed   then try it with a recent version of IE  and you will cry  Of course  there are heuristics  to get it all right  but it will be tedious to grasp all the edge cases  and they will very likely not work anymore in a year s time   Take your code  for example    lt div id  example  gt  lt  div gt   lt script type  text javascript  gt  txt     lt p gt Browser CodeName      navigator appCodeName     lt  p gt    txt     lt p gt Browser Name      navigator appName     lt  p gt    txt     lt p gt Browser Version      navigator appVersion     lt  p gt    txt     lt p gt Cookies Enabled      navigator cookieEnabled     lt  p gt    txt     lt p gt Platform      navigator platform     lt  p gt    txt     lt p gt User-agent header      navigator userAgent     lt  p gt    document getElementById  example   innerHTML txt   lt  script gt    Chrome says      Browser CodeName  Mozilla      Browser Name  Netscape      Browser Version  5 0  Windows NT 6 1  WOW64  AppleWebKit 537 36    KHTML  like Gecko  Chrome 40 0 2214 115 Safari 537 36      Cookies Enabled  true      Platform  Win32      User-agent header  Mozilla 5 0  Windows NT 6 1  WOW64    AppleWebKit 537 36  KHTML  like Gecko  Chrome 40 0 2214 115   Safari 537 36   IE says      Browser CodeName  Mozilla      Browser Name  Netscape      Browser Version  5 0  Windows NT 6 1  WOW64  Trident 7 0  SLCC2   NET   CLR 2 0 50727   NET CLR 3 5 30729   NET CLR 3 0 30729  Media Center PC   6 0   NET4 0C   NET4 0E  InfoPath 3  rv 11 0  like Gecko      Cookies Enabled  true      Platform  Win32      User-agent header  Mozilla 5 0  Windows NT 6 1  WOW64  Trident 7 0    SLCC2   NET CLR 2 0 50727   NET CLR 3 5 30729   NET CLR 3 0 30729    Media Center PC 6 0   NET4 0C   NET4 0E  InfoPath 3  rv 11 0  like   Gecko   At least Chrome still has a string that contains  Chrome  with the exact version number  But  for IE you must extrapolate from the things it supports to actually figure it out  who else would boast that they support  NET or Media Center  P   and then match it against the rv  at the very end to get the version number  Of course  even such sophisticated heuristics might very likely fail as soon as IE 12  or whatever they want to call it  comes out
