Hi, can’t find a solution for this. Have a series of
's. When the
user clicks on one of them, a second series shows in a updated, other
. Works fine with RJS.
But: I'd like to change the background-color for the
clicked in
the first list, so the user can always see and remember which one of
the first list he actually has chosen.
Sounds simple, but I can't figure it out. I've tried a few :onclick
javascript solutions, but they obviously weren't solutioons at all. :-
( Could anybody give me a few hints or so? Thanks in advance.

You could just add a class to the first li (you could do that with
your rjs). If you show what you’ve tried someone might be able to
point out where it’s going wrong.
lets say whe have 50 cups. There must be an easy way to change the
backgroundcolor on the one
that is clicked on, with as little
server-activity as possible. I think a javascript-script should do it,
but I’m afraid I just don’t have enough knowledge of that. I realise
that in a way I have to update the partial, and I’m trying to find an
example that could show me, but I just can’t find it. (Or maybe I just
think it is easy, but it isn’t.)
Thanks for any help anyway. Really appreciate it.
function choose(e)
}
Event.observe(window,‘load’, init);
.chosen { background-color: red; }
And even better would be to wrap this code in a Javascript object
(which prototype conveniently disguises as a Class.create() instead
of using simple functions (that’s just as bad as most of the hobby PHP
projects you see out there IMHO) and use event delegation. This method
will fail as soon as you add list items to the bottom of the list
using ajax (since the click event won’t be bound to the new element),
forcing you to call the init method again. Also, you are binding an
event to each list element, which is quite an expensive operation, and
it certainly will become a problem if you have tens to hundreds of
these listitems on a page.

Wildly overkill for the OP’s situation, I think but a valid point
for
some circumstances.
Still, if you have hundreds of list items on a page, I’d be worrying
more about the basic IA (or lack thereof)…
