javascript - How to get a count of all checked checkboxes on a page

Question

I want to count how many checkboxes a user has selected. For example, from a group of 10 checkboxes if he selects 5, then I want to be able to count it. Using the line:

$(":checkbox:checked")

I can select all of the checked checkboxes, is there a way to get the count of all the elements that are returned by that statement as well?

Answer 1

Use the size() method or the length property. The length property is preferred as it is faster.

Example:

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