| The javascript browser snifer makes an extensive use of regular expressions and the search() and match() functions.
By this function, you can know following information:
[1] browser type
[2] browser version
[3] os type
[4] os version
[5] flash installation information
Actually this script is effective when making web log.
The following is the example of Javascript based Browser Sniffing.
<script type="text/javascript" src="js/brwsniff.js"></script>
<script type="text/javascript">
var br=new Array(4);
var os=new Array(2);
var flash=new Array(2);
br=getBrowser();
os=getOS();
flash=hasFlashPlugin();
document.write("Browser identifier: "+br[0]+"<br />");
document.write("Browser version: "+br[1]+"<br />");
document.write("Browser major version: "+getMajorVersion(br[1])+"<br />");
document.write("Browser minor version: "+getMinorVersion(br[1])+"<br />");
document.write("Browser engine: "+br[2]+"<br />");
document.write("Browser engine version: "+br[3]+"<br />");
document.write("Full user agent string: "+getFullUAString()+"<br />");
document.write("Operating system identifier: "+os[0]+"<br />");
document.write("Operating system version: "+os[1]+"<br />");
document.write("Is Flash installed? " + (flash[0]==2 ? "Yes" : (flash[0] == 1 ? "No" : "unknown")) + "<br />");
document.write("Flash version: "+flash[1]+"<br />");
</script>
