Javascript Only One Checkbox Selected at a Time

In this tutorial, we will learn how to make a function in JavaScript to only allow one checkbox to be selected/checked at a time and get that selected checkbox value. This is useful when you want to create a single-choice question or a radio button-like behavior with checkboxes. We will use the HTML input element with the type attribute set to "checkbox" and the JavaScript addEventListener method to listen for the change event on the checkboxes.

 <script>
  const checkboxes = document.querySelectorAll('input[type="checkbox"]');
  checkboxes.forEach(checkbox => {
   checkbox.addEventListener('change', function() {
    checkboxes.forEach(cb => {
     if (cb !== this) {
      cb.checked = false;
     }
    });
    const result = document.getElementById('result')
    result.innerHTML = `Selected Item: ${this.checked ? this.value : 'No Item Selected'}`;
   });
  });
