If they are guaranteed to appear sequentially in your document, you could do:

<li id="name1">Name1</li>
<li id="name2">Name2</li>

alert($("li[id^=name]:last").attr("id"));

or if you just need the number:

alert($("li[id^=name]").length);

where [id^=name] means that the id attribute starts with ‘name’.
