I am trying to write my first RJS script to uncheck all radio buttons in a div #network_radio_btns

page.select('#network_radio_btns input').each do |element| element.set_attribute('checked', 'false') end

I tested the loop : alert(index) and I can see all indexes but ... how can I change an option ?.... not the value

I'd probably just render a new partial rather then trying to reset the button. If you really need to go this route, I think the visible properties of a radio button depend on the value being nil for unchecked. So you might need to add

element.set_attribute('value', nil)

I haven't tested it though.

maybe i'm missing something, but why would you need to do this using rjs? from your example, you're making a call to the server, which is returning javascript to uncheck all the checkboxes in a div. why not just use straight javascript and skip the server altogether?

assuming all the checkboxes are in a form element, you can do something like this (requires prototype):

<form id="my_form"> ... </form> <%= link_to_function "CHECK ALL", "check_all('my_form')" -%> <%= link_to_function "UNCHECK ALL", "uncheck_all('my_form')" -%>

<script type="text/javascript"> function check_all(form) {   Form.getInputs(form, 'checkbox').each( function(cb) {                                                         cb.checked = true;                                                        }); }

function uncheck_all(form) {   Form.getInputs(form, 'checkbox').each( function(cb) {                                                         cb.checked = false;                                                        }); } </script>
