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? }

This article is quite explanatory: http://msdn.microsoft.com/en-us/library/ms537509%28v=vs.85%29.aspx.

If your JS is unobtrusive, you can just use:

<![if !IE]>
   <script src...
<![endif]>

Solution 2

You can do something like this to include IE-specific javascript:

<!--[IF IE]>
    <script type="text/javascript">
        // IE stuff
    </script>
<![endif]-->

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.
}

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:

<script type="text/javascript">var runFancy = true;</script>
<!--[if IE]>
<script type="text/javascript">
    runFancy = false;
    //any other IE specific stuff here
</script>
<![endif]-->
<script type="text/javascript">
    if (runFancy) {
         //do your code that works with sane browsers
    }
</script>

var browserName=navigator.appName; if (browserName=="Microsoft Internet Explorer") { document.write("Your html for IE") }
