I currently have a site with about 500+ static pages, some of which are in directories etc. so changing a line of code on each page is a real nightmare.

On most of the pages I have an affiliate banner at the bottom, which appears by me inserting this code in the bottom of each page in the source code

<script language="javascript" type="text/javascript" 
  src="http://www.mysite.co.uk/ban.txt"></script>

Then on the server I have a text file called ban.txt and in that text file I have the affiliate code which is javascript.

I'd like to replace the affiliate code with a 728*90 banner and link to a friends site, but I have no idea how to do it without replacing the line of code on every page of my site.

Hopefully someone will know how to do it by just changing the code in the ban.txt file?

Any help would be appreciated

If you want a javascript function to execute (run) it will have to be in a .js file NOT a .txt file.

Other than that you will have to use server side includes.

Thanks for the fast reply Chris

It works at the moment as a txt file

On some setups the .js extension is important and it's a good habit anyway, to distinguish from ordinary text files.Assuming the page HTML doesn't "get in the way", just replace the contents of ban.txt with the appropriate document.writes to get the output you want.I'd create ban.js and try it on a test page, then do a global replace to change from ban.txt

I have sorted it thanks!

The line I used to include the javascript was originally used for a banner rotator, so I have just made the rotator use one image and one url, which still works with the .txt file.

Thanks for the replies
