The navigator object

This script source file uses the function Exami to add a number of properties for the navigator and navigator.examined objects.

Properties set by Exami( )

This function works with JavaScript from language version 1.1 browsers. It should be executed by an event handler not before the document is fully loaded.

navigator.examined.nc4api

Returns a boolean value depending on compliance with Netscape proprietary DOM using document.layers and navigator.kin being "Netscape/4"

navigator.examined.msieapi

Returns a boolean value depending on compliance with Microsoft proprietary DOM using document.all and navigator.kin being "MSIE/4"

navigator.examined.w3cdom

Returns a boolean value depending on compliance with W3C industry DOM standard using document.getElementById and also applying document.getElementsByTagName and document.createElement

navigator.examined.domelementstyle

Returns a boolean value depending on compliance with W3C industry DOM standard (as above) and applying element.style on an element created by document.createElement

navigator.examined.domcreateevent

Returns a boolean value depending on compliance with W3C industry DOM standard (as above) and applying document.createEvent

navigator.appCodeNameSub

Returns a version string representing the compatibility version. The property is intentionally somewhat spoofable. Possible values:

• undefined or null if navigator.appCodeName is not set
• an empty string if the browser is not using Mozilla as the value of navigator.appCodeName
• 3.x (where "3.x" is a version string) JavaScript version 1.1 browsers
• 4.x (where "4.x" is a version string) Fourth generation DHTML browsers
• 5.x (where "5.x" is a version string) Fifth generation browsers returning true for navigator.examined.ecma3 and navigator.examined.w3cdom

navigator.product

This property is already set with a read-only value in some, notably Gecko, browsers as "Gecko". The function will set the property to other browsers. Possible values:

• Gecko
• Trident
• Netscape
• KDE
• Gecko_spoofer
• Opera
• Presto
• Java
• an empty string

The envir object

Exami( ) is calling the Envir function if it's present in order to use it for the creation of the envir object. If it's absent, which is the case if the uaenvir.js file isn't there or the browser wasn't allowed to read it, then it will create envir with one property only.

envir.noenvir

The property indicates the absence of all other envir properties. The boolean value is set to true if Envir( ) is not defined, hence no other properties of the envir object are defined.
