Hello

jQuery

$('#form-id').change(function() {
    if ($('#watch-me').attr('checked')) {
        $('#show-me').show();
    } else {
        $('#show-me').hide();
    }
});

UPDATE 25.01.2013
After Upgrading from jQuery Library 1.8.x to 1.9.x
Please use instead of
jQuery Library 1.8.x

jQuery('#some-id').attr('checked') 

jQuery Library 1.9.x

jQuery('#some-id').prop('checked')
