Argh!!!! Help with something o-f-f-t-o-p-i-c

Sorry for the OT post y'all.. but I can't find this answer - well not
without major major code information that I can't figure out!
 
Basic?
 
I have a series of checkbox arrays like:
 
<input type="checkbox" name="delete[]" value="$row[id]">
 
These are for different records in my DB.
 
 
Now... I want to check (javascript - this is the off topic part :P) if
one of them checkboxes HAS been selected and if so display a confirm
message.
 
This is what I have:
 
function checkform(f) {
 
  var el, e = 0, firstBox, msg = 'You are about to delete something';
 
  while (el = f.elements[e++]) 
 
   if (el.type == 'checkbox' && el.checked) {
    return confirm(msg); 
    return false;
   }
 
  return true;
 
 }
 
Now... this DOES work but with one problem.. I have another checkbox
within the form that does something different but the confirm() will
display if EITHER checkboxes are selected and it SHOULD ONLY be on the
delete[] checkbox.
 
I know.. waaay off topic but I don't know how to reference the names
that are arrays in javascript :(
 
Sorry again all.
