I have a list
<ul>
<li>
<li>
<li>
...
</ul>
I need jQuery to count the number of items in my list.

You don't need jQuery for this. You can use JavaScript's .childNodes.length
.
Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:
var count = elem.childNodes.length - 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.
What if you are using this to determine the current selector to find its children
so this holds: <ol>
then there is <li>
s under how to write a selector
var count = $(this+"> li").length;
wont work..
Try to get using:
var count = $("ul > li").size();
alert(count);
