This is my form. It creates a comment in the database but won’t pass the  
‘body’ value. I think the problem is passing the variable to javascript.  
Can anyone help?

\<% form\_for :comment, :url=\>story\_comments\_path(@story), :name =\>  
‘form’ do |form| %\>

 Comment: 
\<%= form.text\_field :body %\>
 \<%= link\_to\_remote('comment',{ :url =\> {:controller =\> 'comments' , :action =\> 'create', :story\_id =\> @story.id, :method =\> 'get', :with =\> 'serialize\_fields()' }}) %\> \<% end %\>

This is the javascript.

I tried this too

:with=\>"‘body’ + $F(‘body’)"

That doesn’t work either. How can I pass this parameter?

Your serialize\_form method looks borked. You could use the  
remote\_form\_for method alternatively, prototype already provides a  
serialise method for forms - $(‘id\_of\_the\_form’).serialize() will  
serialise all then inputs in the form
