Automatic Breadcrumbs

By Justin Whitford on Oct 5, 2007


This script will automatically build a “breadcrumb” navigational link to any page on your Web site. This allows your visitors to see exactly where they are on your Web site at an given time. Very easy to implement.


  • It wraps the entire breadcrumb trail in a CSS class called “topnav”. You can style this however you like, or you could modify the script to change ‘topnav’ to any CSS class name you want.
  • It names the base directory site “home”. You can modify the script to change the name to something else.
  • It assumes that the homepage of the site is in the root directory of the Web server. If the homepage of your site is actually in a sub-directory, you would need to seriously modify the script.
  • You need to have an index.htm (or equivalent) file in each directory or the user will experience 403 errors.
  • It does not work in frames.
