使用Coldfusion获取浏览器和版本

Question

是否有什么可以让我知道浏览器和版本号在浏览我的网站的Cold聚变？是否有一些现有的库可以让我做到这一点？

除了简单的if语句检测IE之外，我的google并没有展示很多其他的东西。

我确实在Chrome中转储了cgi.http_user_agent变量：

Mozilla/5.0 (WindowsNT5.1) AppleWebKit/534.24 (KHTML，类似壁虎) Chrome/11.0.696.77 Safari/534.24

里面有三种不同的浏览器！如果执行一条if语句，查找这两种语句都会返回true。一定要有更正式的方法吗？

有一个用户定义的函数可以解析出user_agent字符串.

browserDetect

<cfscript>
/**
 * Detects 130+ browsers.
 * v2 by Daniel Harvey, adds Flock/Chrome and Safari fix.
 * 
 * @param UserAgent      User agent string to parse. Defaults to cgi.http_user_agent. (Optional)
 * @return Returns a string. 
 * @author John Bartlett (jbartlett@strangejourney.net) 
 * @version 4, June 28, 2009 
 */
function browserDetect() {

// Default User Agent to the CGI browser string
var UserAgent=CGI.HTTP_USER_AGENT;

// Regex to parse out version numbers
var VerNo="/?v?_? ?v?[\(?]?([A-Z0-9]*\.){0,9}[A-Z0-9\-.]*(?=[^A-Z0-9])";

// List of browser names
var BrowserList="";

// Identified browser info
var BrowserName="";
var BrowserVer="";

// Working variables
var Browser="";
var tmp="";
var tmp2="";
var x=0;


// If a value was passed to the function, use it as the User Agent
if (ArrayLen(Arguments) EQ 1) UserAgent=Arguments[1];

// Allow regex to match on EOL and instring
UserAgent=UserAgent & " ";

// Browser List (Allows regex - see BlackBerry for example)

Answer 2

这比之前提交的复杂函数容易得多.

<CFIF FindNoCase('Chrome','#CGI.HTTP_USER_AGENT#') GREATER THAN 0>
  <CFSET browser = 'Chrome'>
</CFIF>

你能不能不要用javascript代替？http://cssuseragent.org/

CSSUA非常棒，它将简单的类添加到标记中，并允许您使用ua-ie-6等类来实现CSS/Javascript中的目标内容。
