- for(var i in checkboxes){
- checkboxes[i].checked = check.checked;
- }
- var count = document.querySelectorAll('input[name="check[]"]:checked').length;
- document.getElementById('count').innerHTML = count;
- }
- function countCheckbox(){
- var count = document.querySelectorAll('input[name="check[]"]:checked').length;
- document.getElementById('count').innerHTML = count;
