i want a javascript code to disable the script i made if the user is browsing using Internet explorer 8.

4Generally speaking "If using IE8" is a very poor decision point. What is the problem with 8 that you don't have with 7 or 9? Why can't you fix it? Why can't you test for the problem instead of the browser?Quentin– Quentin2011-07-20 14:43:09 +00:00Commented Jul 20, 2011 at 14:43

why disable? you should write javascript code that works on all major browsers and should work on ie8 / 9 tried it with jquery?user753676– user7536762011-07-20 15:05:11 +00:00Commented Jul 20, 2011 at 15:05

Try this.
For disabling script for IE 8
<!--[if !(IE 8)]><!-->
<script src="path/to/external/script"></script>
<script>
// your inline script goes here
</script>
<!--<![endif]-->
For disabling script for IE 8 and above
<!--[if !(gte IE 8)]><!-->
<script src="path/to/external/script"></script>
<script>
// your inline script goes here
</script>
<!--<![endif]-->

in the "path/to/external/script" i will replace it with the external javascript file i want to disable right? What i must add to " // your inline script goes here" ?? I want just to disable the script on IE8

This disable the call in other browsers than IE8+, so it won't work for chrome nor firefox:(
One way to do this would be to use another script, enclosed in IE-specific conditional comments, to deactivate the first one. Of course, this means you need to have some way to deactivate the 1st one, but that's not an IE-specific issue.
Something like this:
<!--[if (gte IE 8) ]><script>deactivate1stScript();</script><![endif]-->
By using the conditional comments, you are letting IE do the work, and no other browser will have to process any extra JavaScript because only IE will pay attention to the code in the comments (and IE8 specifically)
However, I do agree with @Quentin that targeting specific browsers is usually not the best idea. If there is certain functionality that your script needs, such as Canvas or SVG support, using a feature-detection library such as Modernizr is a much better way to deal with this.

See very straightforward solution here How to detect IE8 using JavaScript
The main idea is to run javascript functuion which return version of a current browser and than construct your script usng conditional statements like if, switch

@Wesley Murch: Hey, I wont copy paste content across a intrawebs, the hyperlink specially designed for this purposes. Sometimes hyperlink to a good solution better than posting ugly code or copy paste thm without whole article notes which could be vital, so I'm not sure whether you're right when downvoting my answer

See here: en.wikipedia.org/wiki/Link_rot and here Are answers that just contain links elsewhere really "good answers"? and here Why is linking bad? Adding at least some context to your answer is perfectly fine, especially if you attribute the source as you are doing.

Thanks for the links, I'll read and than reconsider my point of view

The only problem with this solution is that all browsers are penalized because they all will have to run that javascript to determine if they are IE8. People using well behaved browsers (I'm assuming IE8 is not well behaved which is why the other script needs to be deactivated) should not be penalized for IE8 behaving poorly.
