Question

I have tons of checkboxes that are either checked (checked="checked") or unchecked.

I would like to get the number of all checkboxes, unchecked and checked checkboxes.

With check-box I mean <input type="checkbox" />.

How can this be done with jQuery?

Answer 1

You could do:

var numberOfChecked = $('input:checkbox:checked').length;
var totalCheckboxes = $('input:checkbox').length;
var numberNotChecked = totalCheckboxes - numberOfChecked;

EDIT

Or even simple

var numberNotChecked = $('input:checkbox:not(":checked")').length;
