Detect browser version in javascript

[Andy]

Hi,

I'm trying to use javascript to detect the version of internet explorer
before running an active x control. I'm after the full version number
(eg not just IE6 but 6.0.2800.1106). Is there any way of getting this
using javascript?

If not, can anybody suggest how i could go about getting it?

many thanks in advance,

andy

As far as I know, no. Since what you are looking for is an IE browser,
you might want to use JScript or VBScript if they are capable of
detecting the browser's minor version (note that other browsers, such
as FireFox and Netscape, will ignore JScript and VBScript scripts).

When properly identified, a user agent should ignore a language it
doesn't understand. However, JScript is merely another implementation of
ECMAScript, like Mozilla's JavaScript, and many other implementations .

Other user agents may ignore Microsoft-specific extensions like
conditional comments, but not the basic language itself.

var IEVerNumber = prompt('What revision IE do you have?','Click
Help>About Internet Explorer and it will show it to you')

Meaning, you ask the user. Or, you have the ActiveX Control determine
whether it can execute what it wants to or not.

What exactly are you trying to do?

JScript and Javascript, in IE, are synonymous.

for (i in navigator){
document.write( i + ' = ' + navigator[i] + '<br>');
}

Will show you the information that is available from the navigator
object and the Revision Number is not one of them.

No. The HTTP-User-Agent header and so the `userAgent' property of the
object referred to by the global proprietary `navigator' property can
be forged.

Since it more depends on the ActiveX version installed instead of the UA
version (note that Netscape 4+ supports ActiveX as well), it would be more
reasonable to cure the illness instead of the symptoms. Why not check for
the ActiveX support and version and handle missing support accordingly?
