How do I detect IE 8 with jQuery?

I need to detect not only the browser type but version as well using jQuery. Mostly I need to find out if it is IE 8 or not.

I am not sure if I am doing it correctly.

If I do :

if (jQuery.browser.version >= 8.0) {
dosomething}

I am not sure it will work for version 8.123.45.6 or will it?

Edit: Note that JQuery 2+ has dropped support for IE8 and below, and therefore can no longer be used to detect IE8. If using a current version of JQuery, it is necessary to use a Non-JQuery solution.

It is documented in jQuery API Documentation. Check for Internet Explorer with $.browser.msie and then check its version with $.browser.version.

UPDATE: $.browser removed in jQuery 1.9

The jQuery.browser() method has been deprecated since jQuery 1.3 and is removed in 1.9. If needed, it is available as part of the jQuery Migrate plugin. We recommend using feature detection with a library such as Modernizr.

Don't forget that you can also use HTML to detect IE8.

<!--[if IE 8]>
<script type="text/javascript">
    ie = 8;
</script>
<![endif]-->

Having that before all your scripts will let you just check the "ie" variable or whatever.

document.documentMode is undefined if the browser is not IE8,

it returns 8 for standards mode and 7 for 'compatable to IE7'

If it is running as IE7 there are a lot of css and dom features that won't be supported.

You should also look at jQuery.support. Feature detection is a lot more reliable than browser detection for coding your functionality (unless you are just trying to log browser versions).
