This wouldn't necessarily be a bad way to handle this task _if_
srcElement were a DOM standard property of the event object... The
event object itself is part of the DOM, so that's okay. Though it
would be much better to include a similar function in the onMouseOver
event-handler for each item of class "item-b" on your page...
function ItemOver(item) { item.className = 'item-b2'; }
then in your elements <div class="item-b"
onmouseover="ItemOver(this);" />
Unfortunately it doesn't look as though there is a DOM standard syntax
that would really be comparable to your original script. Although in
general looking at the script I have to think to myself "and you want
to do this why?" ... It's designed to change the class-name of objects
once they've been moused-over, but without changing them back on a
mouseout event? ... just seems odd...

This one's reasonably easy... You have to have an element on the page
with the ID (or possibly name) attribute of 'txtitem1' and then you
can replace var eTxt = eval("txt"+eOld.id); with var eTxt =
document.getElementById("txt" + eOld.id);
I would also recommend adding in the {} braces ... I understand that
the code works currently without them but, the less consistent
demarkation your code has (missing {}, missing ; at the end of a
line), the more potential there is for the code to produce undesirable
behavior, whether that's an error or something else.
