Rails - May 2011 - Simple check_box

Hello,

I''m trying create a simple check_box that if checked include a
hidden_field, but I haven''t success.

Something like this:
    <p class="field"></p>
    <%=  check_box_tag(:patrono, value = "1", checked = false,
options {}) %>
    <%= f.label "Patrono" %>
    <% if :patrono.checked == true %>
      <%= f.hidden_field "tipo_componente_ids][", { :id =>
"tipo_componente_ids", :value => @patrono.id } %>
    <% end %>
    <p/>

Thanks for help!

Eric,

You have to write javascript function within the check_box_tag in order 
to verify whether the checkbox is checked or not and then enable the 
hidden field if it is checked.

hi,

use jQuery and then

= f.hidden_field_tag "hidden_field", "value", { :id => 
"hidden_field"}
= f.check_box_tag "name", 1,false,  {:id =>
"my_checkbox"}

jQuery(''#my_checkbox'').bind(''click'',
function() {
  jQuery(''#hidden_field'').attr(''disabled'',
!jQuery(this).attr(''checked''));
}

when field is disabled, it''s not taken into account when form is sent

PS: if not using jQuery, it''s simple to do with DOM too, just add
:onClick=''disableField()''  to the checkbox and
function disableField() {
	document.getElementById(''hidden_field'').disabled =
!document.getElementById(''my_checkbox'').checked;
       return false;
}
