我想检测用户是否使用IE和Firefox,但我找不到脚本.

我的代码如下:

$(document).ready(function(e) {
    $.browser.chrome = /chrom(e|ium)/.test(navigator.userAgent.toLowerCase()); 
    if($.browser.chrome){
        alert(1);
             //this work well
    }
            else if(//the browser is IE){alert(2);}
            else if(//the browser is Firefox){alert(3);}

   //The problem is that I don't know how to write a script for IE and FireFox browser for chrome is work fine
 )};

I have the PHP code as below:

<?php
  echo "<tr></tr>";
  //ouput I want : <tr></tr>
?>

当输出我想要显示<tr></tr>.但我不知道我应该使用的whitch功能,任何人都知道请帮帮我,谢谢
