Cuffs - code and effect comment?

Dr J R Stockton · May 24, 2007

<URL:http://www.merlyn.demon.co.uk/js-index.htm>, and js-dates.htm, and
some Easter pages, now include <BODY onload="Cuffs()">.

function Cuffs() { var ThisPage, ThisSite, J, DLJ, HREF
ThisPage = location.href.replace(/#.*/, "")
ThisSite = location.protocol + "//" + location.hostname + "/"
for (J in document.links) {
DLJ = document.links[J] ; HREF = DLJ.href
if (!HREF) continue // why an undefined ?
HREF = String(HREF)
if (HREF.indexOf(ThisPage) == 0) DLJ.title = "." ;
else if (HREF.indexOf(ThisSite) == 0) DLJ.title = "+" ;
else if (HREF.indexOf("http://") == 0) DLJ.title = "#" ;
else DLJ.title = "*" } }

Comment on the code or its effect?

Why does HREF = String(HREF) seem needed?

Only tested in XP sp2 IE6 & FF 2.0.0.3.

That would be due to the fact that your iteration construct causes all
properties of the document.links object to be included, many of which
you do not wish to access. Try

for ( J = 0; J < document.links.length; ++J ) {
...
}

I've been able to return to this code (which is now used in most of
those of my pages which use the corresponding Include file).

Understood; tested; OK; thanks.
