Hi,

I’m looking to create a form that gets submitted using AJAX after an  
element loses focus.

\<% remote\_form\_for :person, @person, :url =\> { :action =\> “save” },  
:update =\> ‘form’ do |f| %\>

\*Name

\<%= f.text\_field :naam, :size=\>50, :onblur =\> 'this.form.submit()' %\>

\<% end %\>

This doesn’t work though, it submits the form using a plain old POST.  
Any ideas on how to accomplish this?

Thanks in advance,

Jeroen

This seems to work:

\<%= f.text\_field :name, :size=\>50,  
:onblur =\> remote\_function(:update =\> “form”,  
:with =\> ‘Form.serialize(this.form)’,  
:url =\> { :action =\> :presubmit }) %\>

Cheers,

Jeroen
