Need a script which detects browser version ?

[chrbar]

Hello,

I would like to use ThickBox script in my Web page (http://jquery.com/demo/thickbox/), but this script is supported on Safari 2.0.4+ and my Web page has to be compatible with Safari 2.0.3 too!

Do you know a script which detects browser version?

A script which allows to use a specific code line depending of the browser version, like:

if Safari 2.0.4 =
<a href="ajaxOverFlow.html?height=300&width=300" title="add a caption to title attribute / or leave blank" class="thickbox">Scrolling content</a>
(ThickBox code)

if Safari 2.0.3 =
<a href="test.html" target="_parent">test</a>
(classic code)

Thanks a lot your help ;)
