Everytime MS comes out with a new browser I have great expectation for it and they never fail to dissapoint. They always make more work for us developers instead of making sure that they are as close to 100% w3 standards compliant, javascript compliant, and just compliant. We are at the breaking point of not supporting any IE browsers any more because of all the hassle.

Dave, IE8 is W3C compliant with HTML 4 and CSS 2.1. It's more compliant than any other browser! Is there anything in particular you think it should behave in a different way in IE8? I'm happy to discuss openly on existing issues, as long as the conversation is constructive and it's not based on browser religions or bad assumptions :-)

Thanks!

Thanks for the code, Now I have another question. Since my original javascript code to detect IE 8 was wrong how do I know my detection for Windows 7 is correct. To note: I do not have a computer which has windows 7 on it now to test this. I have also search the web and could not find anything good.

Here is the code I have so far:

var OSName="Unknown OS";

var OS = navigator.appVersion;

if (!ie)

{

//document.write("THIS IS NOT IE");

OS = navigator.userAgent;

}

if (OS.indexOf("Win")!=-1) {

if ((OS.indexOf("Windows NT 5.1")!=-1) || (OS.indexOf("Windows XP")!=-1))

OSName="Win XP";

else if ((OS.indexOf("Windows NT 7.0")!=-1))

OSName="Win 7";

else if ((OS.indexOf("Windows NT 6.0")!=-1))

OSName="Win Vista/Server 08";

else if (OS.indexOf("Windows ME")!=-1)

OSName="Win ME";

else if ((OS.indexOf("Windows NT 4.0")!=-1) || (OS.indexOf("WinNT4.0")!=-1) || (OS.indexOf("WinNT")!=-1))

OSName="Win NT";

else if ((OS.indexOf("Windows NT 5.2")!=-1))

OSName="Win Server 03";

else if ((OS.indexOf("Windows NT 5.0")!=-1) || (OS.indexOf("Windows 2000")!=-1))

OSName="Win 2000";

else if ((OS.indexOf("Windows 98")!=-1) || (OS.indexOf("Win98")!=-1))

OSName="Win 98";

else if ((OS.indexOf("Windows 95")!=-1) || (OS.indexOf("Win95")!=-1) || (OS.indexOf("Windows_95")!=-1))

OSName="Win 95";

else if ((OS.indexOf("Win16")!=-1))

OSName="Win 3.1";

else

OSName="Win Ver. Unknown";

if (OS.indexOf("WOW64")!=-1) OSName=OSName+"(x64)"

else OSName=OSName+"(x32)"

}

else if (OS.indexOf("Mac")!=-1) OSName="MacOS";

else if (OS.indexOf("X11")!=-1) OSName="UNIX";

else if (OS.indexOf("Linux")!=-1) OSName="Linux";

Hi Doug,

if the OS is Windows 7, the userAgent will contain

the new Windows NT token: Windows NT 6.1.

Check out this post for more information:

Hope this helps

I may have found it on this website.

It did not come right out say "here is the code"

But it did say

The major version for windows 7 =6

And the minor version for windows 7 = 1

or add this javascript code:

|| (OS.indexOf("Windows NT 6.1")!=-1))

to the windows 7 detection line.

OF COURSE I STILL HAVE NO WAY TO TEST THIS....

PLEASE HELP.

Thanks,

I tried the following code for an alternate style sheet under IE8 (tried on XP) another under previous IE versions and the last for all other navigators and it doesn't work.

it returns the alert message -1 when i'm under IE8

here is the code:

function getInternetExplorerVersion()

// Returns the version of Internet Explorer or a -1

// (indicating the use of another browser).

{

var rv = -1; // Return value assumes failure.

if (navigator.appName == 'Microsoft Internet Explorer')

{

var ua = navigator.userAgent;

var re = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");

if (re.exec(ua) != null)

rv = parseFloat( RegExp.$1 );

}

return rv;

}

var ver = getInternetExplorerVersion();

if ( ver = -1 )

{

document.write("<link rel='stylesheet' href='css/vcod.css' type='text/css'>");

alert (ver);

}

else if (( ver > -1 ) && ( ver < 8.0 ))

{

document.write("<link rel='stylesheet' href='css/vcod_IE.css' type='text/css'>");

alert (ver);

}

else if ( ver >= 8.0 )

{

alert (ver);

document.write("<link rel='stylesheet' href='css/vcod_IE8.css' type='text/css'>");

}

help may be useful
