我有一个只在mozilla和chrome上运行的jquery插件，并且不会在IE中运行＆lt; 10个版本，所以我必须使用备用插件，所以我如何运行这个脚本浏览器专门我尝试了这个，但没有工作。

 <![if gte IE 8]>
<script type="text/javascript">

</script>

<p>You're using a recent version of Internet Explorer.</p>
<![endif]>

<![if lt IE 7]>

<script type="text/javascript">

</script>

<![endif]>

<![if !IE]>
<script type="text/javascript">

    alert("IE 7");
</script>
<![endif]>

Answer 1

 <script type="text/javascript">
//userAgent in IE7 WinXP returns: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727)
//userAgent in IE11 Win7 returns: Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

if (navigator.userAgent.indexOf('MSIE') != -1)
 var detectIEregexp = /MSIE (\d+\.\d+);/ //test for MSIE x.x
else // if no "MSIE" string in userAgent
 var detectIEregexp = /Trident.*rv[ :]*(\d+\.\d+)/ //test for rv:x.x or rv x.x where Trident string exists

if (detectIEregexp.test(navigator.userAgent)){ //if some form of IE
 var ieversion=new Number(RegExp.$1) // capture x.x portion and store as a number
 if (ieversion>=1){
      alert("ie")
 }
}
else{
alert ("other brower");
}
