Trouble with Links--How to import filehandle into link?

[Guest_imported]

I am currently redesigning a large website. As part of the process, I have created printer friendly versions of every single web page. I would like to create a link on each formatted page to its printer friendly version using a script so that I do not have to do it manually on over a thousand different pages.

The printer friendly pages have the same name as their formatted versions, but are saved in a sub-directory called /ptr. I do not know how to automate this process so that the printer friendly link on each page automatically imports that page's filehandle.

For example, if the webpage was named:

http://www.time.com/home.html

the link createed by the script would link to

http://www.time.com/ptr/home.html

Does anyone know how to do this or have any ideas?

Thanks in advance for any tips.

Try something like:

<script>
document.write( &quot;<a href='ptr&quot; + location.pathname + &quot;'>Printer Friendly</a>&quot; );
</script>

Thanks so much to Neil! I'm almost there now. Just one more problem - is there a way to extract just the filename? I also have "ptr" directories in my site's subdirectories, such as:

http://www.time.com/next/level/home.html

(formatted)

http://www.time.com/next/level/ptr/home.html

(printable)

The "location.pathname" operator gives me the complete filename, resulting in a printer link that looks like:

/next/level/ptr/next/level/home.html

One method using split and join:

tokens = location.href.split( "/" );
file   = tokens[ tokens.length - 1 ];
tokens[ tokens.length -1  ] = "ptr";
tokens[ tokens.length ]     = file;
document.write( '<a href=&quot;' + tokens.join( &quot;/&quot; ) + '&quot;>TEST</a>' );

What this does is create an array of tokens where the href contained '/' characters. It then saves the filename stored in the last tokens slot, replaces this with the string "ptr", and then appends the filename. The href is then reconstructed using join.
Some browsers may not support split and join though :-(

Another way using regular expressions:

href = location.href.replace( /(\/[^\/]+$)/, "/ptr$1" );
document.write( '<a href=&quot;' + href + '&quot;>TEST</a>' );

The regular expression is:

\/      - literal '/'
[^\/]+  - one or more of any character except '/'
$       - anchored to end of string

The replace string is:

/ptr    - literal string
$1      - replace contents matched in ( ) of regular expression

This may be more browser friendly.... Cheers, Neil s-)
