[thelist] [DHTML] Elements with the same ID

[Keith Dahlby]

Each call to getElementsByTagName() likely generates a unique temporary 
array of the appropriate elements, which wastes memory and processor 
cycles.  Thus for better performance (and cleaner code):

function hideall(hiddenContentElement, hiddenContentClass)
{
         var hiddenElements = 
document.getElementsByTagName(hiddenContentElement);
         for (i=0; i<hiddenElements .length; i++)
                 if (hiddenElements .item(i).className == hiddenContentClass)
                         hiddenElements .item(i).style.display = "none";
}

That said, this is an excellent implementation using the class attribute as 
it is intended.  Good work David!
