Many JavaScript libraries  especially non-recent ones  do not handle IE9 well because it breaks with IE8 in the handling of a lot of things   JS code that sniffs for IE will fail quite frequently in IE9  unless such code is rewritten to handle IE9 specifically   Before the JS code is updated  you should use the  X-UA-Compatible  meta tag to force your web page into IE8 mode   EDIT  Can t believe that  3 years later and we re onto IE11  and there are still up-votes for this    -   Many JS libraries should now at least support IE9 natively and most support IE10  so it is unlikely that you ll need the meta tag these days  unless you don t intend to upgrade your JS library   But beware that IE10 changes things regarding to cross-domain scripting and some CDN-based library code breaks   Check your library version   For example  Dojo 1 9 on the CDN will break on IE10  but 1 9 1 solves it   EDIT 2  You REALLY need to get your acts together now   We are now in mid-2014     I am STILL getting up-votes for this   Revise your sites to get rid of old-IE hard-coded dependencies   Sigh     If I had known that this would be by far my most popular answer  I d probably have spent more time polishing it     EDIT 3  It is now almost 2016  Upvotes still ticking up     I guess there are lots of legacy code out there     One day our programs will out-live us

You could also get this error if you are viewing accessing the page locally  via file    instead of http        There is some discussion about this here  https   github com jeromegn Backbone localStorage issues 55

Well  you should also try adding the Javascript code into a function  then calling the function after document body has loaded  it worked for me

I have written code that sniffs IE4 or greater and is currently functioning perfectly in sites for my company s clients  as well as my own personal sites     Include the following enumerated constant and function variables into a javascript include file on your page       methods var BrowserTypes         Unknown  0      FireFox  1      Chrome  2      Safari  3      IE  4      IE7  5      IE8  6      IE9  7      IE10  8      IE11  8      IE12  8     var Browser   function          try             declares         var type          var version          var sVersion             process         switch  navigator appName toLowerCase                  case  microsoft internet explorer                   type   BrowserTypes IE                  sVersion   navigator appVersion substring navigator appVersion indexOf  MSIE     5  navigator appVersion length                   version   parseFloat sVersion split      0                    switch  parseInt version                         case 7                          type   BrowserTypes IE7                          break                      case 8                          type   BrowserTypes IE8                          break                      case 9                          type   BrowserTypes IE9                          break                      case 10                          type   BrowserTypes IE10                          break                      case 11                          type   BrowserTypes IE11                          break                      case 12                          type   BrowserTypes IE12                          break                                    break              case  netscape                   if  navigator userAgent toLowerCase   indexOf  chrome    gt  -1    type   BrowserTypes Chrome                    else   if  navigator userAgent toLowerCase   indexOf  firefox    gt  -1    type   BrowserTypes FireFox                      break              default                  type   BrowserTypes Unknown                  break                       returns         return type        catch  ex               Then all you have to do is use any conditional functionality such as     ie  value    Browser    gt   BrowserTypes IE    node text   node textContent   or WindowWidth      Browser    gt   BrowserTypes IE9      Browser    lt  BrowserTypes IE     window innerWidth   document documentElement clientWidth    or sJSON    Browser    gt   BrowserTypes IE    xmlElement text   xmlElement textContent   Get the idea   Hope this helps   Oh  you might want to keep it in mind to QA the Browser   function after IE10 is released  just to verify they didn t change the rules
