tricky js question

[801119]

if I have this html code:
<span id=&quot;folder1&quot;> hello 1 </span>
<span id=&quot;folder2&quot;> hello 2 </span>
<span id=&quot;folder3&quot;> hello 3 </span>
<a href=&quot;JavaScript:show(1)&quot;>Show / hide 1</a>
<a href=&quot;JavaScript:show(2)&quot;>Show / hide 2</a>
<a href=&quot;JavaScript:show(3)&quot;>Show / hide 3</a>

how do I simpliest write the JS code?
this is what I know, (dummy code)
folder1.style.visibility = &quot;visible&quot;;
but how do I use something like this
folder[num].style.visibility = &quot;visible&quot;; ???
My codes look like something a kid wrote
I have absolutely no idea what I am talking about
Somehow I still manage to make it work

Try:
function show(num) {
fld = eval(&quot;folder&quot; + num);
fld.style.visibility = &quot;visible&quot;;
}
