do you mean you want to re-order the span tags that you have or do you
mean you want to go through each one and change the text within each
one?

ok i just re-read your post, it seems like you want to replace the text
inside the tags. For this, each tag has to have a unique id, so going
from your example you could have this:
<div id="all_items">
<div class="item">Item #<span class="itemNo" id = "1">1</span></div>
<div class="item">Item #<span class="itemNo" id = "2">2</span></div>
<div class="item">Item #<span class="itemNo" id = "3">3</span></div>
<div class="item">Item #<span class="itemNo" id = "4">4</span></div>
</div>
that MIGHT work, it probably doesn't but i think you get the idea. you
have to loop through each span class item that you want to change and
change the value...Also I don't profess to be a l33t ruby haxor or
anything so there's almost definitely a better way of doing this.
Thanks for your reply. The DIVs of class "item" and the SPANs within
them are getting dynamically inserted and the SPANs don't contain
IDs. I was hoping I could do this without having to assign them one.
I tried your code anyway, but I get the RJS alert error box, "RJS
Error: Type error: items[i] has no properties".
This may be because I didn't have id's in those SPANs.
If there is a way to do it without having to assign IDs to the SPANs,
I am most grateful, - Dave
Just so you know, it's possible to write javascript that is much much
nicer with prototype
$$('#all_items .itemNo').each(function(element,index) {element.
innerHTML = index + 1})
There's really no need to mess around with the dom by hand.

aha! finally! I knew there'd be a way but I just couldn't find it...this
is a problem i have with ruby: If you don't know what you're looking
for, how do you find it?!
There is an excellent book on prototype which was an absolute eye-opener for me (
