How can I toggle radiobutton

Question

Say this is my HTML:

Answer 1

I use an onClick() like the following for my custom radios:

$(function(){
  // if selected already, deselect
  if ($(this).hasClass('selected') {
    $(this).prop('checked', false);
    $(this).removeClass('selected');
  }
  // else select
  else {
    $(this).prop('checked', true);
    $(this).addClass('selected');
  }
  // deselect sibling inputs
  $(this).siblings('input').prop('checked', false);
  $(this).siblings('input').removeClass('selected');
}
