Rails spinoffs - Jun 2007 - problem with getElements, getInputs in Prototype

I''ve following code:

<script src="javascripts/prototype.js"
type="text/javascript"></
script>

<form id="user">
  <input type="text" id="username"
name="username" value="abc" />
</form>

<script type="text/javascript">
  var form = $(''user'');
  var a = form.getElements();
  alert(a);
</script>

what pops up is [object] in IE, and [object HTMLInputElement] in
Firefox

what went wrong???

Thanks.

It doesn''t look like anything is wrong.  Why are you so sure  
something has failed?

The implicit "toString()" that is called when you alert echoes the  
values in the array. (In Firefox, they''re comma separated,  Dunno  
about IE--I''m on a Mac at the moment.)
javascript: alert([1,2,3]);

When the toString() for the input element is called, IE produces the  
unhelpful [object], while Firefox is more explicit on the object  
type.  Both are correct.

So, what''s the problem?
