| Sniffer Script |
| Description: This browser sniffer detects all the major browsers currently out there, and passes the results on as variables to facilitate your browser detection needs. It differentiates between Windows, Mac and Linux, and the most commonly used DHTML browsers - IE4/5/6, Netscape 4/6/7/other Gecko, Konqueror 2.2+, Safari, Opera 5/6/7. All other browsers are grouped together under a single exclude variable, to protect them from complex scripting. |
| Directions: Simply paste the following script at the beginning of the <HEAD> section, so that other scripts on the same page can have access to its variables. If you use it on more than one page, consider saving the script as an external .js file, so that it caches: |
