Rails - Jun 2006 - how can I get the value of a hidden field and pass it

My problem is that I want to pass a date information form one page to 
another. And that information came to my page in an Ajax petition.
My idea to accomplish this is that the date can come in the Ajax 
response as a hidden field and when I click a link I can get that hidden 
field value and pass it to the action in rails as a param.
I have done all this. I have the date in a hidden field and I have 
access to that field with "document.hidden_form.hidden_date.value" but
I
don''t know how to introduce this value in a rails variable as @date to 
pass it with
<%= link_to ''New event'', :action =>
''new'' , :date_start_day=>@date%>

thank you in advance

if you have any other idea about how to pass that information from an 
Ajax response to another page please tell me I have no more ideas

<%= link_to ''New event'', :action =>
''new'' ,:with => "''ate_start_day='' +
Form.Element.getValue(''hidden_field_parameter'')"%>
