The uaenvirsniff.js help file

If a property or value is struck, it is deprecated and would possibly be undefined in later releases of the script.

The navigator object

This script source file uses the functions Exami and xbDetectBrowser to set a number of properties for the exami and navigator objects.

Properties set or modified by xbDetectBrowser

This is partly derivative work on the now dated Practical Browser Sniffer.

navigator.version

Initially set to equal navigator.appVersion. Returns a number. The property value will normally be changed to the brand specific version number. However, if the browser is spoofing as another browser, notably Opera like Internet Explorer, the spoofed version number will be used instead.

navigator.rversion

The release version number for Gecko based browsers will be reported in double floating points, i.e. version 1.7 will read "1.07" and version 1.7.5 "1.0705". Other browsers will report 0.

navigator.rv

The actual release version (cp. navigator.rversion above).

• string

navigator.prettyName

The popular name (or brand) of the browser. It will equal the navigator.vendor value, if the browser, notably Gecko browsers, has that property set other than to an empty string. Possible values for other browsers:

• Internet Explorer
• OmniWeb
• ANT Fresco
• Konqueror
• iCab
• AOL
• HotJava Browser
• Opera
• Apple
• Netscape
• Compuserve
• Mozilla
• an other string (based on the first part of navigator.userAgent)
• an empty string

navigator.product

navigator.product is already set in some browsers. The script will set the property to other browsers. If not specified below, it will equal the formerly used navigator.family property, but with an upper-case first letter.

Note that navigator.product is normally not spoofable, but Safari calls its product for "Gecko".

• "Opera" all Opera browsers (regardless of spoofing attempts)

• "Trident" Internet Explorer versions 4 and later (the name is an early denomination for the rendering engine)

• "Netscape" Netscape Navigator 3.x or 4.x browsers

• "Gecko" Gecko based browsers (regardless of spoofing attempts) and Safari

• "Gecko_spoofer" browsers presumably trying to spoof as Gecko

• "KDE" KHTML based browsers, e.g. Konqueror

navigator.productSub

navigator.productSub is already set in some browsers as the build date. The script will set the property to other browsers as an empty string.

navigator.kin

navigator.kin contains a string referring to the browsers’ assumed kinship. It differs from the formerly used navigator.family by applying to all browsers and it is not influenced by the user agent string. The string is a combination of navigator.appName and navigator.appVersion. Case is preserved.

Note that navigator.kin is spoofable.

navigator.appName+'/'+parseInt(navigator.appVersion) is resolving the string for all browsers, except for Internet Explorer. Examples are listed below.

• "Opera/N" Opera browsers (if spoofing is not used) where "N" represents the application version number 3, 4, 5, 6, 7 or 8

• "MSIE/4" Internet Explorer versions 4 and later

• "Netscape/N" Netscape Navigator 3.x or 4.x browsers

• "Netscape/5" Gecko based browsers such as Netscape versions 6 and later or Mozilla 1.x

Properties set or modified by Exami

navigator.appCodeNameSub

navigator.appCodeNameSub is representing the browser's "generation". It's based on the number next to "Mozilla/" in the user agent string, but it is evaluated in the context of the DHTML capabilities of the browser, and may accordingly have been adjusted. This somewhat spoofable property will return a string.

• "3.x" e.g. Netscape Navigator 3.x (where x is a stringed number)

• "4.x" DHTML browsers (where x is a stringed number)

• "5.x" Standards compliant browsers using "DOCTYPE switching" (where x is a stringed number)

• "" if the browser is not using "Mozilla" as the value of navigator.appCodeName

navigator.js

The JavaScript version number is set to 1.1, 1.2 or 1.3*

• number

  *The special indicator of version 1.5 has been removed.

The exami object

exami.foe

If the browser is identified by this property the script will simply stop and nothing will happen. exami.foe is intended to refuse certain browsers.

• boolean

exami.ECMA

The browser is compliant with the ECMA-262 standard for script languages.

• boolean

exami.productSub

The build date (cp. navigator.productSub).

• number, e.g. 20040306

• NaN -- if navigator.productSub was an empty string

exami.appCodeNameSub

The browser "generation" (cp. navigator.appCodeNameSub).

• number, e.g. 5
