Answer 1

Support for multiple groups and pre-checked.

$('input').click(function() {
    var $t = $(event.target);
    if ($t.hasClass('checked')) $t.removeAttr('checked');
    else $('input[type="radio"][name="' + $t.prop('name') + '"]').not($t).removeClass('checked');
    $t.toggleClass('checked');
}).filter(':checked').addClass('checked');​

```
