jQuery: Count number of list elements?

Question

Try:

$("#mylist li").length

Just curious: why do you need to know the size? Can't you just use:

$("#mylist").append("<li>New list item</li>");

?

var listItems = $("#myList").children();

var count = listItems.length;

Of course you can condense this with

var count = $("#myList").children().length;

For more help with jQuery, http://docs.jquery.com/Main_Page is a good place to start.

You have the same result when calling .size() method or .length property but the .length property is preferred because it doesn't have the overhead of a function call. So the best way:

$("#mylist li").length

I think this should do it:

var ct = $('#mylist').children().size();
