AJAX Libraries - Continuous Forms

I'm not sure if this fits what you're looking for, but you could just have a button to add a new field. So:

Code:

<form id='items_form'>
     <input type='text' name='items[]'/>
</form>
<button id='add_new_item'>Add an Item</button>

&lt;script type='text/javascript'>
$('#add_new_item').bind('click', function(){
     $('#items_form').append("&lt;input type='text' name='items[]'/&gt;");
});
&lt;/script>

I'm probably totally missing your point.
