I’m just starting to play with rjs, I have an index page with a  
remote\_form\_for to create new items. That’s working. However, after  
the ajax updates my container, the input form needs to be cleared.  
I’m not sure how to do that

Can you show the partial \_form …?

There is an error when you use @empty in this line:

> page.replace\_html ‘create\_form’, {:partial=\>‘form’, :object=\> @empty}

the @empty object is a Choice model and you are using it in your \_form  
partial like a Form object… ‘text\_field’ is not defined in a Choice  
object.

thank you, yes, I realize the empty Choice object is not correct, that  
is my question. I’m looking for suggestion how to clear the form  
fields from the rjs.

The \_form.html.erb is quite simple

**Prompt**  
 \<%= form.text\_field :prompt %\>

Ok, you can do this using rjs… first mark the form with an html id  
(‘my\_form’). After, you can use in the rjs template something like this:

page[‘my\_form’].reset()
