Conditional comment for 'Except IE8'?

Question

I'm using  for targeting IE8, but there's some JS that I want to load for all browsers EXCEPT IE8, what conditional comment should I use?

Edit: I wonder if this would work: 

Thanks

The *lte* option will include the JS in IEs before 8.0 but not in non-IE browsers. — Siddhartha Reddy, Nov 07 '09 at 05:48
LTE means Less-Than-or-Equal. If you want strictly less-than, use LT instead. — EricLaw, Nov 24 '09 at 23:18

For something to appear in ‘other browsers’ that don't support CCs, you need a downlevel-revealed conditional comment.

<!--[if !IE 8]><!-->
    ....
<!--<![endif]-->

(this is slightly different to Microsoft's official syntax which is not valid HTML.)

“All browsers except IE8” is an unusual requirement, are you sure that's what you want? What about future versions of IE?

+1 That's one heck of a clever trick with the nested comments. – Raynos Feb 17 '11 at 13:06
I assume you could use your code with if "gte IE 8" if you want to hide it from future IE releases, right? – ph33nyx Sep 13 '12 at 15:40
@ph33nyx: Yes, that would be a much more usual kind of test than `if !IE8`. – bobince Dec 03 '13 at 17:50

I can think of a trick. Set a variable inside the IE conditional tag and include your JS code if that variable isn't set.

<script>
    var ie8 = false;
</script>

<!--[if IE 8]>
    <script>
        ie8 = true;
    </script>
<![endif]-->

<script>
    if (ie8 == false) {
        // any code here will not be executed by IE 8
        alert("Not IE 8!");
    }
</script>

The best solution to this problem I've come across, and I should know. I've spent the whole day trying to do this with purely conditional statements! – mickburkejnr Jul 08 '14 at 15:56
That was a very good trick, Siddhartha. And the ability to put your mind back in the dust of time that is IE ;) – narration_sd Jan 24 '15 at 01:03

Try negation, [if !IE 8] perhaps?

Then IE9 comes out and you will have rather interesting behavior. Of course at this point I wouldn't be surprised if IE displayed rainbows and unicorns instead of what I intended. – Matt Nov 07 '09 at 05:56
