I'm using a JS plugin that styles checkbox/radio input elements and used the following jQuery to establish a 'readonly state' where the underlying value is still posted but the input element appears inaccessible to the user, which is I believe the intended reason we would use a readonly input attribute...

if ($(node).prop('readonly')) {
    $(node).parent('div').addClass('disabled'); // just styling, appears greyed out
    $(node).on('click', function (e) {
        e.preventDefault();
    });
}
