How to count CheckBoxList checked using Jquery

I have search with the following keyword but couldn't find.

javascript CheckBoxList api

jquery CheckBoxList check开发者_Python百科ed count

The following should give you the total number of checked checkboxes on the page

var count = $(':checkbox:checked').length;

If you want to restrict it only to a given CheckBoxList you could assign this checkboxlist some class and then:

var count = $('.someClass :checkbox:checked').length;
