Folks, Help appreciated - I'm building a node form where the form will reveal/hide portions depending on the users choices. To do this I'm using jQuery to manipulate the DOM. I'm having a lot of issues with the radio buttons. What I want to do is have a message pop up if the user selects a particular radio button (in this case a "no" choice of a "Yes/No" "set"). For this to work I need to attach an "onClick" handle to the "no" radio button and when the user clicks evaluate and display the message. Because of a series of interrelated issues I've tried a number of approaches. The one I'm working on now is: - I'm using the form APIs "radios" - an issue here is that "radios" define the actual radio buttons in an array and it doesn't look like there is a way to assign an id attribute using the forms api (as a matter of fact there is code in form.inc which explicitly strips out an ID at that level). - I assign an onClick handler to the "radios" - #attributes' => array('onClick' => 'CitizenClick()') - On form load I assign an id to the specific radio button I'm interested in - $("[name=CitizenQ][value=no]").attr('id', 'CitizenNoButton'); - In CitizenClick() I check and take action depending - if ( $("#CitizenNoButton").attr('checked') ) { - Please note that although I could do all this without an "id" and by selecting the "name" instead of the "id" - it was very slow Everything works - EXCEPT - I am placing the radio buttons inside of a fieldset thusly - $form['Qualifyers'] = array( '#type' => 'fieldset', '#tree' => TRUE, '#weight' => 1, ); $form['Qualifyers']['CitizenQ'] = array( '#type' => 'radios', '#title' => t('Are you a U.S. Citizen?'), '#default_value' => 1, '#options' => array('yes' => t('Yes'), 'no' => t('No')), '#attributes' => array('onClick' => 'CitizenClick()'), ); If I don't place it within the fieldset I can select the radio with - $("[name=CitizenQ][value=no]") However withing the fieldset I can't get this to work - $("[name=Qualifyers[CitizenQ]][value=no]") I assumed the above wouldn't work because the "[]" are special characters so I tried escaping them - $("[name=Qualifyers\\[CitizenQ\\]][value=no]") Still no joy - I have been beating my head against this for a while and would appreciate some assistance - also if I've approached this in a fundamentally wrong way please let me know. Thanks! Dan
