[Javascript] Dynamic breadcrumbs script

[Paul Novitski]

Kevin,

I figured out what you meant by the possessive pronoun "your" in your 
posting: you were thinking that a script you found in the LaTech JavaScript 
archives is the collective child of the current listserve 
membership.  Instead, this listserve is a loose collection of individuals 
each contributing their own bits to the collective soup.  Any script 
contributed by a listserve member is the intellectual child of that member, 
and may not be known to or understood by other members.  Not a critical 
distinction, but one worth noting for future reference.

I suspect that the script you're referring to is the dynamic breadcrumbs 
script written by Harry Love, as described in
https://lists.latech.edu/pipermail/javascript/2002-August/004019.html

His script is located at
<http://healthlinks.washington.edu/scripts/dynacrumbs.js>http<http://healthlinks.washington.edu/scripts/dynacrumbs.js>://healthlinks.washington.edu/scripts/dynacrumbs.js

Quickly perusing Harry's script, I see that it creates breadcrumb links in 
the format
         Base > node > node > node
from the current page's URL.

In a quick test, I didn't see the final node (the html file itself) 
included in the breadcrumb array, regardless of its file name (index.html 
or dynacrumbs.html).  It seems clear that Harry was deliberately omitting 
that node.

The final for/next loop of the script begins this way (where urlL is the 
number of nodes in the URL):

         if(urlL>2)
         {
                 for(x=startPoint+1;x<urlL;x++)
                 {
                         if(x<urlL-1)

In other words, that last if-test is excluding the final node of the 
array.  If you change that last line to:

                         if(x<urlL)

then your html file name will be displayed.  You might wish to tweak the 
display by deleting the file extension, etc.

Good luck,
Paul
