If Browser is Internet Explorer run an alternative script instead

Question

I m using an image carousel script that is quite heavy on the browser  It works great in Opera and Chrome  half decent in FF and absolutely breaks my balls in IE  So i d like to give IE users an alternative of simple HTML without any action JS    The script doesn t use MT or jQuery and its like 380 lines of JS  Would it be possible to give IE users a plain HTML alternative   var browserName navigator appName   if  browserName   Microsoft Internet Explorer        what command can i use

You define a boolean value with default of true  and then inside an IE conditional comment  set the value to false  and use the value of this to determine whether your advanced code should run   Something like    lt script type  text javascript  gt var runFancy   true  lt  script gt   lt  -- if IE  gt   lt script type  text javascript  gt      runFancy   false        any other IE specific stuff here  lt  script gt   lt   endif -- gt   lt script type  text javascript  gt      if  runFancy               do your code that works with sane browsers        lt  script gt

Here is the script i used and it works like a charm  I used the boolean method Ender suggested as the other ones using only the IE specific script adds something to IE but doesn  t take the original code out        lt script gt runFancy   true  lt  script gt   lt  -- if IE  gt   lt script type  text javascript  gt      runFancy   false    lt  script gt      lt div gt The HTML version for IE went here lt  div gt   lt   endif -- gt          Below is the script used for all other browsers       lt script src  accmenu acac1 js  charset  utf-8  type  text javascript  gt  lt  script gt  lt script gt ac1init doc    0  lt  script gt

Note that you can also determine in pure js in what browser you script is beeing executed through   window navigator userAgent  However  that s not a recommended way as it s configurable in the browser settings  More info available there  https   developer mozilla org fr docs DOM window navigator userAgent

For IE10  standard conditions don t work cause of engine change or some another reasons  cause  you know  it s MSIE  But for IE10  you need to run something like this in your scripts   if  navigator userAgent match  Trident  7             do stuff for IE

this code works well on my site because it detects whether its ie or not and activates the javascript if it is its below you can check it out live on ie or other browser Just a demo of the if ie javascript in action   lt script type  text javascript  gt   lt  -- if IE  gt  window location href    http   yoursite com     lt   endif -- gt   lt  script gt
