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

<p>If your JS is unobtrusive, you can just use:</p>

<pre><code>&lt;![if !IE]&gt;
   &lt;script src...
&lt;![endif]&gt;
</code></pre>


blocks|key|5412804|text|您可以这样做，以包含特定于IE的javascript：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5412805||code-block|syntax|javascript|5412806|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>You can do something like this to include IE-specific javascript: </p>

<pre><code>&lt;!--[IF IE]&gt;
    &lt;script type="text/javascript"&gt;
        // IE stuff
    &lt;/script&gt;
&lt;![endif]--&gt;
</code></pre>


blocks|key|5412926|text|对于IE10%2B标准条件不起作用的原因是发动机更换或其他一些原因，原因，你知道，这是MSIE。但是对于IE10%2B，你需要在你的脚本中运行类似这样的东西：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5412927|if+(navigator.userAgent.match(/Trident\/7\./))+{
++//+do+stuff+for+IE.
}|code-block|syntax|javascript|5412928|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>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:</p>

<pre class="lang-js prettyprint-override"><code>if (navigator.userAgent.match(/Trident\/7\./)) {
  // do stuff for IE.
}
</code></pre>


blocks|key|1884841|text|您定义了一个布尔值，其默认值为true，然后在IE+conditional+comment中，将该值设置为false，并使用该值来确定高级代码是否应该运行。类似于：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1884842|<script+type="text/javascript">var+runFancy+=+true;</script>

<script+type="text/javascript">
++++if+(runFancy)+{

</script>|code-block|syntax|javascript|1884843|entityMap|0|LINK|mutability|MUTABLE|url|http://www.quirksmode.org/css/condcom.html^0|N|M|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$G|H]]|$1|I|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

<p>You define a boolean value with default of true, and then inside an <a href="http://www.quirksmode.org/css/condcom.html" rel="noreferrer">IE conditional comment</a>, set the value to false, and use the value of this to determine whether your advanced code should run.  Something like:</p>

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

blocks|key|1563724|text|这是我使用的脚本，它的效果很不错。我使用了Ender建议的布尔方法，因为其他方法只使用IE特定的脚本，向IE添加了一些东西，但没有取出原始代码。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1563725|++++<script>runFancy+=+true;</script>


++++//+Below+is+the+script+used+for+all+other+browsers:

<p>Here is the script i used and it works like a charm. I used the boolean method Ender suggested as the other ones using only the IE specific script adds something to IE but doesn´t take the original code out.</p>

<pre><code>    &lt;script&gt;runFancy = true;&lt;/script&gt;
&lt;!--[if IE]&gt;
&lt;script type="text/javascript"&gt;
    runFancy = false;
 &lt;/script&gt; // &lt;div&gt;The HTML version for IE went here&lt;/div&gt;
&lt;![endif]--&gt;

    // Below is the script used for all other browsers:
    &lt;script src="accmenu/acac1.js" charset="utf-8" type="text/javascript"&gt;&lt;/script&gt;&lt;script&gt;ac1init_doc('',0)&lt;/script&gt; 
</code></pre>


blocks|key|1560255|text|试试这个:+systemLanguage和userLanguage在所有浏览器中都是未定义的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1560256|if(navigator.userLanguage+!==+"undefined"+&&+navigator.systemLanguage+!==+"undefined"+&&+navigator.userAgent.match(/trident/i))+{

<p>Try this:
The systemLanguage and the userLanguage is undefined in all browser. </p>

<pre><code>if(navigator.userLanguage !== "undefined" &amp;&amp; navigator.systemLanguage !== "undefined" &amp;&amp; navigator.userAgent.match(/trident/i)) {
    alert("hello explorer i catch U :D")
  }
</code></pre>


blocks|key|1884925|text|注意，您还可以在纯js中确定您的脚本是通过哪个浏览器执行的:+window.navigator.userAgent|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1884926|但是，这不是推荐的方式，因为它可以在浏览器设置中进行配置。欲了解更多信息，请访问：https://developer.mozilla.org/fr/docs/DOM/window.navigator.userAgent|offset|length|1884927|entityMap|0|LINK|mutability|MUTABLE|url|https://developer.mozilla.org/fr/docs/DOM/window.navigator.userAgent^0|0|15|1W|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

<p>Note that you can also determine in pure js in what browser you script is beeing executed through : window.navigator.userAgent</p>

<p>However, that's not a recommended way as it's configurable in the browser settings. More info available there: <a href="https://developer.mozilla.org/fr/docs/DOM/window.navigator.userAgent" rel="nofollow">https://developer.mozilla.org/fr/docs/DOM/window.navigator.userAgent</a></p>

<p>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. </p>

<p>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?</p>

<p><code>var browserName=navigator.appName; 
if (browserName=="Microsoft Internet Explorer")
{
// what command can i use?
}</code></p>


If Browser is Internet Explorer: run an alternative script instead
