Browser Name =========================== - browser.isMozilla true if the browser is Mozilla (and not Netscape 6.x); false otherwise. Note, no revision version information is available for Mozilla browsers (Mozilla 0.9.8 will have a navigator.versionMinor of 5) - for Mozilla and all Gecko-based browsers, use the navigator.geckoVersion for version information. - browser.isNS true if the browser is any version of Netscape; false otherwise. - browser.isNS4x true if the browser is any version of Netscape 4.x; false otherwise. - browser.isNS40x true if the browser is any version of Netscape 4.0x (4.00 to 4.08); false otherwise. - browser.isNS47x true if the browser is any version of Netscape 4.7x (4.70 - 4.79); false otherwise. - browser.isNS4up true if the browser is any version of Netscape 4.00 or higher; false otherwise. - browser.isNS6x true if the browser is any version of Netscape 6.x; false otherwise. - browser.isNS6up true if the browser is any version of Netscape 6.00 or higher; false otherwise. - browser.isNS7x true if the browser is any version of Netscape 7.x; false otherwise. - browser.isNS7up true if the browser is any version of Netscape 7.00 or higher; false otherwise. - browser.isIE true if the browser is any version of IE; false otherwise. - browser.isIE4x true if the browser is any version of IE 4.x; false otherwise. - browser.isIE4xMac true if the browser is any version of IE 4.x on the Mac; false otherwise. - browser.isIE4up true if the browser is any version of IE 4.00 or greater; false otherwise. - browser.isIE5x true if the browser is any version of IE 5.x; false otherwise. - browser.isIE55 true if the browser is IE 5.5; false otherwise. - browser.isIE5up true if the browser is any version of IE 5.00 or greater; false otherwise. - browser.isIE6x true if the browser is any version of IE 6.x; false otherwise. - browser.isIE6up true if the browser is any version of IE 6.00 or greater; false otherwise. - browser.isOpera true if the browser is any version of Opera; false otherwise. - browser.isSafari true if the browser is any version of Safari; false otherwise. - browser.isOmniweb true if the browser is any version of OmniWeb; false otherwise. - browser.isKonqueror true if the browser is any version of Konqueror (assuming a default user-agent configuration); false otherwise. - browser.isIcab true if the browser is any version of iCab (assuming a default user-agent configuration); false otherwise. - browser.isAol true if the browser is any version of AOL; false otherwise. - browser.isNSCompatible true if the browser reports itself to be Netscape or Mozilla but isn't; false otherwise. - browser.isIECompatible true if the browser reports itself to be IE but isn't; false otherwise. Browser Engine Version =========================== - browser.geckoVersion Contains the Gecko version date (in YYYYMMDD format) for Gecko-based browsers; for non-Gecko browsers, it will evaluate to -1. - browser.equivalentMozilla Contains the version number of Mozilla that would be equivalent to current browser for Gecko-based browsers (NS6+, Firebird, K-Meleon, Camino, Galeon, etc); for non-Gecko browsers, it will evaluate to -1. - browser.appleWebKitVersion Contains the AppleWebKit build number for AppleWebKit-based browsers (Safari, OmniWeb4.5+); for non-AppleWebKit browsers, it will evaluate to -1. Browser Version =========================== - browser.versionMajor Contains the integer version number for the browser (for instance, the value of navigator.versionMajor for Netscape 4.07 is 4). - browser.versionMinor Contains the full version number for the browser (for instance, the value of navigator.versionMajor for Netscape 4.07 is 4.07). Browser Capabilities =========================== - browser.isDOM1 true if the browser supports DOM level 1; false otherwise. - browser.isDOM2Event true if the browser supports DOM level 2 events; false otherwise. - browser.mode Mirrors document.compatMode but available in all browsers - BackCompat for quirks mode or CSS1Compat for Strict mode. Platform / Operating System =========================== - browser.isWin true if the platform is Windows-based; false otherwise. - browser.isWin32 true if the platform is Windows 32bit (Win95, Win98, WinNT, Win2000, WinME); false otherwise. - browser.isMac true if the platform is a Macintosh; false otherwise. - browser.isUnix true if the platform is a Unix, SunOS or BSD variant; false otherwise. Because of the huge number of *nix operating systems, this property isn't foolproof. - browser.isLinux true if the platform is a Linux variant; false otherwise. Because of the huge number of *nix operating systems, this property isn't foolproof. --------------------------------------------------------------------------------- ===============================================================================*/ function BrowserDetect() { var ua = navigator.userAgent.toLowerCase(); // browser engine name this.isGecko = (ua.indexOf('gecko') != -1 && ua.indexOf('safari') == -1); this.isAppleWebKit = (ua.indexOf('applewebkit') != -1); // browser name this.isKonqueror = (ua.indexOf('konqueror') != -1); this.isSafari = (ua.indexOf('safari') != - 1); this.isOmniweb = (ua.indexOf('omniweb') != - 1); this.isOpera = (ua.indexOf('opera') != -1); this.isIcab = (ua.indexOf('icab') != -1); this.isAol = (ua.indexOf('aol') != -1); this.isIE = (ua.indexOf('msie') != -1 && !this.isOpera && (ua.indexOf('webtv') == -1) ); this.isMozilla = (this.isGecko && ua.indexOf('gecko/') + 14 == ua.length); this.isFirebird = (ua.indexOf('firebird/') != -1); this.isNS = ( (this.isGecko) ?
