JScript code

var SysLan = window.navigator.systemLanguage;
if(SysLan == "zh-cn")window.location = "http://www.baidu.com";
if(SysLan == "en-us")window.location = "index.php?id=471"; 
// JS代码是没问题的
你的location路径不对  应该是绝对路径

------解决方案--------------------
var wn=window.navigator;
if (wn.systemLanguage=="zh-cn" || wn.language=="zh-CN") {  
window.location.href = "index.php?id=191";
}else if (wn.systemLanguage=="en" || wn.language=="zh-EN") {  
window.location.href = "index.php?id=471";
} else{
window.location.href = "index.php?id=191";//默认中文页面
}

楼主可以在不同的浏览器下运行以下脚本看看结果：

JScript code

<script type="text/javascript">
document.write(navigator.browserLanguage+'<br>');
document.write(navigator.platform+'<br>');
document.write(navigator.cookieEnabled+'<br>');
document.write(navigator.cpuClass+'<br>');
document.write(navigator.onLine+'<br>');
document.write(navigator.platform+'<br>');
document.write(navigator.systemLanguage+'<br>');
document.write(navigator.userAgent+'&
