Actually even that's not good enough. The 'elements' array has members
such as 'length' and 'item', which you wouldn't want to iterate over.
The for...in loop in JavaScript doesn't iterate over Arrays in the way
you might think (as it does in other languages), it only runs over the
list of member names. This is of course of very little practical use,
but then JavaScript has never been designed in anything like a sane way.
You still have to use the old-fashioned indexed-iterator for-loop for
this purpose.
Also you'd want to avoid 'document.megasearch' to retrieve the <form
name="megasearch">; putting named forms into the Document object is
non-standard and probably doesn't work on all browsers.
'document.forms.megasearch' would be the 'correct' documented JS way of
doing it; if you're using <form id="megasearch"> (and hence ignoring
Netscape 4) you could also use document.getElementById('megasearch').
var elements= document.forms.megasearch.elements;
for (var i= 0; i<elements.length; i++) {
var element= elements[i];
}
