How do i reuse a function several times on one page?

Question

I would like to stop a function so it can run multiple times on one page. It is some radio buttons which i would like to be cleared if a checkbox is clicked. It should work with an infinite number of products. I'm the worst on javascript so i hope i could get an answer?

Sample:

$('.product .question-input').change(function() {
  if ($(this).is(':checked')) { //radio is now checked
    $('.product .question-checkbox').prop('checked', false);
  }
  return false;
});

$('.product .question-checkbox').change(function() {
  if ($(this).is(':checked')) {
    $('.product .question-input').prop('checked', false);
  }
  return false;
});

Answer 1

By passing a reference to a handler instead of directly passing the handler function:

function handler() {
  if ($(this).is(':checked')) {
    $('.product .question-input').prop('checked', false);
  }
  return false;
}

$('.product .question-input').change(handler);

$('.product .question-checkbox').change(handler);
