I think the best way would be this:

From HTML5 boilerplate:

<pre><code>&lt;!--[if lt IE 7]&gt; &lt;html lang="en-us" class="no-js ie6 oldie"&gt; &lt;![endif]--&gt;
&lt;!--[if IE 7]&gt; &lt;html lang="en-us" class="no-js ie7 oldie"&gt; &lt;![endif]--&gt;

&lt;!--[if gt IE 8]&gt;&lt;!--&gt; &lt;html lang="en-us" class="no-js"&gt; &lt;!--&lt;![endif]--&gt;
</code></pre>

in JS:

<pre><code>if( $("html").hasClass("ie8") ) { /* do your things */ };
</code></pre>

especially since <a href="http://api.jquery.com/jQuery.browser/"><code>$.browser</code></a> has been removed from jQuery 1.9+.

&lt;/script&gt;
&lt;![endif]--&gt;

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

Assuming...

<ul>
<li>...that it's the crunky rendering engine of old versions of IE you're interested in detecting, to make a style look right in old IE (otherwise, use feature detection)</li>
<li>...that you can't just add conditional comments to the HTML - e.g. for JS plugins that can be applied to any page (otherwise, just do the trick of conditional classes on <code>&lt;body&gt;</code> or <code>&lt;html&gt;</code>)</li>
</ul>

...then this is probably the best trick (based on <a href="https://stackoverflow.com/a/10965203/568458">this non-jQuery, slightly less flexible variant</a>). It creates then tests for then removes an appropriate conditional comment. 

(Conditional comments are ignored in IE10+ 'standards mode' - but that should be fine since IE10+ 'standards mode' doesn't have a crazy rendering engine!)

Drop in this function:

<pre><code>function isIE( version, comparison ){
 var $div = $('&lt;div style="display:none;"/&gt;');

 // Don't chain these, in IE8 chaining stops some versions of jQuery writing the conditional comment properly
 $div.appendTo($('body'));
 $div.html('&lt;!--[if '+(comparison||'')+' IE '+(version||'')+']&gt;&lt;a&gt;&amp;nbsp;&lt;/a&gt;&lt;![endif]--&gt;');

 var ieTest = $div.find('a').length;
 $div.remove();
 return ieTest;
}
</code></pre>

Then use it like this:

<pre><code>if(isIE()){ /* runs in all versions of IE after 4 before standards-mode 10 */ }

if(isIE(8)){ /* runs in IE8 */ }

if(isIE(9)){ /* runs in IE9 */ }

if(isIE(8,'lte')){ /* runs in IE8 or below */ }

if(isIE(6,'lte')){ /* if you need this, I pity you... */ }
</code></pre>

I'd also suggest caching the results of this function so you don't have to repeat it. For example, you could use the string <code>(comparison||'')+' IE '+(version||'')</code> as a key to store and check for the result of this test in an object somewhere.

Note:

1) $.browser appears to be dropped in jQuery 1.9+ (as noted by Mandeep Jain). It is <a href="http://api.jquery.com/jQuery.browser/">recommended</a> to use <a href="http://api.jquery.com/jQuery.support/">.support</a> instead.

2) <a href="http://api.jquery.com/jQuery.browser/">$.browser.version</a> can return "7" in IE >7 when the browser is in "compatibility" mode.

3) As of IE 10, <a href="http://msdn.microsoft.com/en-us/library/ie/hh801214%28v=vs.85%29.aspx">conditional comments</a> will no longer work.

4) jQuery 2.0+ will drop <a href="http://blog.jquery.com/2012/06/28/jquery-core-version-1-9-and-beyond/">support for IE 6/7/8</a>

5) document.documentMode appears to be defined only in Internet Explorer 8+ browsers. The value returned will tell you in what "compatibility" mode Internet Explorer is running. Still not a good solution though.

I tried numerous .support() options, but it appears that when an IE browser (9+) is in compatibility mode, it will simply behave like IE 7 ... :(

So far I only found this to work (kind-a):

(if documentMode is not defined and htmlSerialize and opacity are not supported, then you're very likely looking at IE &lt;8 ...)

<pre><code>if(!document.documentMode &amp;&amp; !$.support.htmlSerialize &amp;&amp; !$.support.opacity)

You can use $.browser to detect the browser name. possible values are :

<ul>
<li>webkit (as of jQuery 1.4)</li>
<li>safari (deprecated)</li>
<li>opera</li>
<li>msie</li>
<li>mozilla</li>
</ul>

or get a boolean flag: $.browser.msie will be true if the browser is MSIE.

as for the version number, if you are only interested in the major release number - you can use parseInt($.browser.version, 10). no need to parse the $.browser.version string yourself.

Anyway, The $.support property is available for detection of support for particular features rather than relying on $.browser.

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 :

<pre><code>if (jQuery.browser.version &gt;= 8.0) {
dosomething}
</code></pre>

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.

How do I detect IE 8 with jQuery?

jQuery

HTML5

我不仅需要检测浏览器的类型，而且还需要使用jQuery检测版本。大多数情况下，我需要找出它是否是IE8。我不确定我做得是否正确。如果我这样做了：if (jQuery.browser.version >= 8.0) {dosomething}我不确定它是否能在8.123.45.6版本中工作，或者它能工作吗？编辑:请注意，JQuery 2+已放弃对IE8及更低版本的支持，因此不能再用于检测IE8。如果
