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
