jquery get checked checkboxes

Question

i'm trying to get the list of checkboxes and the count that are checked. I have this:

        var obj = $(this).closest('li').find(':checkbox');

        var childCount=$(obj).size();
        var checkedCount=$(obj).(':checked').length;

I get error on checkedCount

??

Answer 1

to get checked checkboxes length :

$('input[name^="complete"]:checked').length;

to get unchecked checkboxes length :

$('input[name^="complete"]:unchecked').length;

where "complete" is a name attribute.
