[thelist] Image rollover check

[Julian Rickards]

There are a number of words/phrases to describe what I am refering to:
unobtrusive and DOM scripting are just two. What is meant by these phrases
is that the JavaScript does not exist in the page but rather, like CSS, the
script is designed to search for the appropriate element (via tags, IDs,
classes or other attributes) and then act upon it. I used to call it remote
scripting because the JavaScript was separate or distant from the component
on which it worked. For example, for your rollover script, you might have
<img id="comicstrip"... /> and then in the JavaScript code, have it search
for the ID of comicstrip using getElementById and then run the rollover.

I am not very good at JavaScript so I can't really talk much more about this
but if you have PHP programming skills, you should be able to pick up the
concept fairly quickly. I would recommend Jeremy Keith's DOM Scripting book
as a first start along with Christian Heilmann's online tutorials at
http://onlinetools.org/. After that, I would recommend Christian's
book<http://www.amazon.com/exec/obidos/ASIN/1590596803/onlinetoolsorg/103-1380453-3336648>and
ppk's
book <http://www.amazon.ca/ppk-JavaScript-Peter-Paul-Koch/dp/0321423305>.

Given my statement above, your assumption that my review of your JS code
puts a stamp of approval on it is wrong: I can't really comment on the code
other than it works in FF. There are lots of good DOM script-type rollovers
available that would ensure that all browsers capable of running a rollover
will do so correctly.

Best of luck,

Jules
