<%= check_box “mercado”, “nombre”, {:value=>mercado.id,
:name=>mercado.nombre},
:onchange => remote_function(:url => {:action => “find2”}, :with
=> “‘id=#{mercado.id}’”) %> <%=mercado.nombre%>

the onchange should be part of the same options has as :value and :name

The check_box helper doesn’t take an :onchange option. You want to use
observe_field to watch the check_box status.

HTH,

Shandy, Fred;

Thanks! I never knew we could use remote_function this way. Learning
something new every day!

Best regards,
Bill

You want to use :onclick. I have the same code (well, almost) in one of
my apps. The only difference is that my remote_function call’s value is
placed within a variable:

<% func1 = remote_function(:url => {:action => “find2”}, :with => “‘id=#
{mercado.id}’”) %>
<%= check_box “mercado”, “nombre”, {:value=>mercado.id,
:name=>mercado.nombre},
:onclick => func1 %>
