I need jQuery to count the number of items in my list.

Answer 1

You can do this using jQuery:

This method gets a list of its children then counts the length of that list, as simple as that.

$("ul").find("*").length;

The find() method traverses DOM downwards along descendants, all the way down to the last descendant.

Note: children() method traverses a single level down the DOM tree.
