$10 by PayPal to the first person who replies with a working javascript I can include in my HTML that will load an external javascript file (in the format JavascriptFile.js) only if the visitor is running Internet Explorer 5 or lower under Windows 98 or lower. If you're going to PM or email, also reply here saying that, so there's no debate about who responded first. There are scripts like this all over that just need a little tweaking to do exactly what I want, so it shouldn't be too hard for someone who knows what they are doing. Unfortunately, that's not me (Grin).

This should do it:

Code:

<script language="JavaScript">

<!-- begin head script

var browserName = navigator.appName

var browserVersion = navigator.appVersion

var browserVersionNum = parseFloat(browserVersion)

var agt=navigator.userAgent

var yourOS="unknown"

osok=0

if ((agt.indexOf("Win95")!=-1)||(agt.indexOf("Windows 95")!=-1)) 

   {
   yourOS='Windows 95'
   osok=0
   }
   

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

   {
   yourOS='Windows 98'
   osok=0
   }

if ((agt.indexOf("WinNT")!=-1)||(agt.indexOf("Windows NT")!=-1))

   {
   yourOS='Windows NT'
   osok=1
   }

if ((agt.indexOf("Win16")!=-1)||(agt.indexOf("Windows 3.1")!=-1))

   {
   yourOS='Windows 3.<i>x</i>'
   osok=0
   }



//Detect IE5.5+
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])
browserok=0
}

if (version<=5) //NON IE browser will return 0
	{browserok=1}

dontallow=0
if (osok==0)
	dontallow=1
if (browserok==0)
	dontallow=1
	
if (dontallow==1)
	document.write('<script language="JavaScript" src="filetoinclude.js"><\/script>')



//-->

</script>

It seems to work on my computer but It'll need to be tested a bit more.

As shown in my Apache log file, using the above script, in the last few minutes the server has given the "filetoinclude.js" script to the following browser types:

Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC)
Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)

So, it appears to be serving only to Internet Explorer users, but all version of Internet Explorer, and all operating systems.

Still won't work though if the person has javascript disabled...

**david** · 05-31-2003, 08:31 AM

Hmm... How about this one:

Code:

<script language="JavaScript">

<!-- begin head script

var browserName = navigator.appName

var browserVersion = navigator.appVersion

var browserVersionNum = parseFloat(browserVersion)

var agt=navigator.userAgent

var yourOS="unknown"

osok=1

if ((agt.indexOf("Win95")!=-1)||(agt.indexOf("Windows 95")!=-1)) 

   {
   yourOS='Windows 95'
   osok=0
   }
   

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

   {
   yourOS='Windows 98'
   osok=0
   }

if ((agt.indexOf("WinNT")!=-1)||(agt.indexOf("Windows NT")!=-1))

   {
   yourOS='Windows NT'
   osok=1
   }

if ((agt.indexOf("Win16")!=-1)||(agt.indexOf("Windows 3.1")!=-1))

   {
   yourOS='Windows 3.<i>x</i>'
   osok=0
   }



//Detect IE5.5+
version=0
if (navigator.appVersion.indexOf("MSIE")!=-1){
temp=navigator.appVersion.split("MSIE")
version=parseFloat(temp[1])

}

if (version>=5) //NON IE browser will return 0
	{}
else
	{
		if (osok==0)
			// document.write('<script language="JavaScript" src="filetoinclude.js"><\/script>')
			document.write('did it')
	}

</script>

I will try that second script first thing on Monday, and post the results. Thanks.

**Shiftlock** · 06-02-2003, 11:09 AM

Still no good. The second script isn't serving the external javascript file to anyone, no matter what platform or browser.

**dk01** · 06-02-2003, 01:43 PM

Ok can you use php because if you can I have a script that is much more reliable than javascript and just as easy to use.
-dk

**Shiftlock** · 06-02-2003, 01:46 PM

I've never used php, and don't really know anything about it. My server is running Apache 1.3 under Windows 2000 Advanced Server.

**dk01** · 06-02-2003, 08:28 PM

Do you have php installed?
You can check by creating a new page with this as the source:

PHP Code:


			
<?php echo("Hello world!"); ?>

If opening the page on your server in internet explorer does not show "Hello world!" then you do not have php installed. Oh and by the way... the file must be called myfile.php instead of the normal myfile.html.
-dk

**Shiftlock** · 06-04-2003, 11:10 AM

Nope, my server is not configured for PHP. I really wanted to do it in JavaScript. I didn't think it would be hard. Oh well.
