Demo : http://ads.sina.com.hk/demo/200909/browser_detection.html

var userAgent = navigator.userAgent.toLowerCase();
 
// Figure out what browser is being used
jQuery.browser = {
 version: (userAgent.match( /.+(?:rv|it|ra|ie|me)[\/: ]([\d.]+)/ ) || [])[1],
 chrome: /chrome/.test( userAgent ),
 safari: /webkit/.test( userAgent ) && !/chrome/.test( userAgent ),
 opera: /opera/.test( userAgent ),
 msie: /msie/.test( userAgent ) && !/opera/.test( userAgent ),
 mozilla: /mozilla/.test( userAgent ) && !/(compatible|webkit)/.test( userAgent )
};

var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );

$(document).ready(function(){ 
   $.each($.browser, function(i, val) {
  $("
" + i + " : " + val + "
")
  .appendTo(document.body);
   });
});
