下面是我整理的一些userAgent大家先看看格式

我的机器的
Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
Maxthon
傲游 1.x 系列的 UserAgent 值是 “Maxthon”，傲游 2.0 的 UserAgent 值是 “Maxthon 2.0″。所以只需要通过程序在 User-Agent 字符串中查找是否出现 “Maxthon” 或者 “Maxthon 2.0″
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322)

一般来讲只需要判断浏览器的内核就可以了
像遨游1.X版本腾讯的TT浏览器都是IE6的核心
如果没有特殊需要可以不加区分
下面的例子只按浏览器核心判断是那种浏览器
//获取userAgent
var sUserAgent = window.navigator.userAgent;
//获取红色字体的部分Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
var fAppVersion = parseFloat(window.navigator.appVersion);
//比较版本大小后面的程序会用到，如果不熟悉split和push方法请参照《JavaScript学习笔记1：Array类》
function compareVersions(sVersion1, sVersion2)
{
var aVersion1 = sVersion1.split(".");
var aVersion2 = sVersion2.split(".");
if (aVersion1.length > aVersion2.length)
{
for (var i = 0; i < aVersion1.length - aVersion2.length; i++)
{
aVersion2.push("0");
}
}
else if (aVersion1.length < aVersion2.length)
{
for (var i = 0; i < aVersion2.length - aVersion1.length; i++)
{
aVersion1.push("0");
}
}
for (var i = 0; i < aVersion1.length; i++)
{
if (aVersion1[i] < aVersion2[i])
{
return -1;
}
else if (aVersion1[i] > aVersion2[i])
{
return 1;
}
}
return 0;
}
//判断userAgent字符串里面是否有Opera字段，有则设isOpera为true，下面还会用到
var isOpera = sUserAgent.indexOf("Opera") > -1;
var isMinOpera4 = isMinOpera5 = isMinOpera6 = isMinOpera7 = isMinOpera7_5 = false;

if (window.navigator.appName == "Opera")
{

}
//这里判断的是伪装后的（某些伪装情况下在userAgent中不会出现Opera字样对这种情况我们无能为力，不过毕竟是极少
//数），关于Opera的伪装请自己查看相关资料
else

注意：上面的对操作系统和浏览器判断的先后顺序是不能改变的，类似于排除法
现在好多的Ajax框架里都有这个东东可以拿来直接用，
写的有点匆忙，后面很多地方和前面用的方法相同就没有复述
如果你和我一样是新手欢迎和我交流，我的邮箱是zyyn2000【at】21cn.com，最近正在学ASP.NET Ajax相关的技术，也请高手指点
如果你想看自己的userAgent在浏览器上敲这个就可以了^_^ javascript:document.write(navigator.userAgent)
这个东西我还写了一个C#版的，方便一次性识别大量的userAgent^_^
我的作文很少及格写的不好大家见笑了，欢迎批评指正。
