[thelist] Javascript: altering BG color of multiple divs with one click

[Dunstan Orchard]

Thanks for all the comments on this guys.

Marcus <marcan at home.se> said "I really don't know why you would want to do this,
but okay..."

Well, the reason I wanted to do it was to add some functionality to a blog
comments system I was making. If you're interested you can see it explained here:

Though it's certainly had some holes shot in it, I'm still pleased with the
result. And I couldn't have done it without your help, so danke.

Ah yes, good point, I saw that written down for PHP the other day, I must
remember it. Thanks.


Cheerio - Dunstan

p.s. If you ever find yourself building a system that uses Javascript's onclick,
and you change that behaviour to ondblclick for testing purposes, be sure not to
go for lunch and forget what you did. You could spend two hours frantically
stripping everything from your code trying to find out why the system no longer
works when you 'click' :o)
