• what value do you get in numberOfChecked? – Rohan Commented Feb 20, 2014 at 6:05
• @Rohan The value getting is 0 – Arun Commented Feb 20, 2014 at 6:07
• 1 For this to work, you need to write a function which will be called on every checkbox check/uncheck which should update the numberOfChecked. – SajithNair Commented Feb 20, 2014 at 6:07

try adding thois code. It should work

    $(document).ready(function () {

        var numberOfChecked = $('input:checkbox:checked').length;
        var totalCheckboxes = $('input:checkbox').length;
        $('.getScore').text(numberOfChecked);
        $('.totalScore').text(totalCheckboxes);

        $("input[type=checkbox]").change(function () {
            var numberOfChecked = $('input:checkbox:checked').length;
            $('.getScore').text(numberOfChecked);
         });
    }); 

Here is the code

 $('form').on('click', function(){
    $('.totalScore').text( $('input:checked').length )
  });

Fiddle Demo

For this to work, you need to write a function which will be called on every checkbox check/uncheck which will update the value.

Check this js fiddle http://jsfiddle/4UdYQ/

var numberOfChecked;
$(document).ready(function () {


    var totalCheckboxes = $('input:checkbox').length;
    numberOfChecked = $('input:checkbox:checked').length;
        $('.getScore').text(numberOfChecked);
        $('.totalScore').text(totalCheckboxes);

}); 

$('input[type=checkbox]').change(function() {
    numberOfChecked = $('input:checkbox:checked').length;
        $('.getScore').text(numberOfChecked);
});

try this code for getting count of checked checkboxes

var numberOfChecked = $("[type='checkbox']:checked").length;

$(document).ready(function () {
    $('.totalScore').text($('input:checkbox').length);
    $('.getScore').text($('input:checkbox:checked').length)

    $(':checkbox').on('click', function() {
        $('.getScore').text($('input:checkbox:checked').length);
    });
})
