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;
}
