You can also use the below code to get all checked checkboxes values. <script> document.getElementById('btn').onclick = function() { var markedCheckbox = document.querySelectorAll('input[type="checkbox"]:checked'); for (var checkbox of markedCheckbox) { document.body.append(checkbox.value + ' '); } } </script>
