Could you please elaborate a little bit more?

What do you mean by “saving in the same view”?

I want to catch the value of num\_titulos for pass this value to action  
comprueba, but I don´t know how I do it.

td\>

**numero de titulos a comprar:** \<%= f.text\_field  
:num\_titulos, :size=\> 10 %\>

**Elija el precio al que compro:** \<%= f.text\_field :precio\_compra, {:size=\> 10, :onchange =\> "#{remote\_function(:url=\>{:controller=\> "accions", :action=\> "comprueba"},:with =\>"'valor='+ value")}"} %\>

thanks for all

If it is inside a form and that form points to the right action then  
that field will be passed in via the params hash
