You can do it by using name attibute  class  id or just universal checkbox  If you want to count only checked number of checkbox   By the class name    var countChk      checkbox myclassboxName checked   length    By name attribute    var countByName     checkbox name myAllcheckBoxName  checked   length    Complete code     checkbox className   blur function           count only checked checkbox         checkbox name myAllcheckBoxName  checked   length

Assume that you have a tr row with multiple checkboxes in it  and you want to count only if the first checkbox is checked   You can do that by giving a class to the first checkbox  For example class  mycxk  and you can count that using the filter  like this      mycxk   filter   checked   length

There are multiple methods to do that   Method 1   alert     checkbox class here checked   size       Method 2   alert    input name checkbox name    attr  checked       Method 3   alert     checkbox checked   length

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
