Count the number of checked checkboxes in HTML

Question

So basically i want to count the number of checkboxes that are ticked. I get my code to the point where it counts them successfully, but I want to put in an alert that shows the number of checkboxes ticked, the code does this but doesn't show the total count, it increments the total every refresh. I just want to know how I can show a total count.

It should display the total when the radio button 'yes' is clicked.

<br />Apples <input type="checkbox" name="fruit" />Oranges <input type="checkbox" name="fruit" />Mango <input type="checkbox" name="fruit" /> <br />Yes <input type="radio" name="yesorno" id="yes" onchange="checkboxes()" 

function checkboxes(){     var inputElems = document.getElementsByTagName("input"),     count = 0;     for (var i=0; i<inputElems.length; i++) {     if (inputElems[i].type === "checkbox" && inputElems[i].checked === true){         count++;         alert(count);     } }} 

Answer 1

This should do the trick:

alert(document.querySelectorAll('input[type="checkbox"]:checked').length);
