jQuery $(this).val returns 0
<p>I have a simple list like this:</p>

<pre><code>&lt;ul id="large_box_custom_list"&gt;
&lt;li id="8" class="large_box"&gt;Item 1&lt;/li&gt;
&lt;li id="13" class="large_box"&gt;Item 2&lt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>then I have a jQuery function like this:</p>

<pre><code>$(function() { 
$('li.large_box').css('cursor', 'pointer')
.click(function() {
    var show_id = $(this).val();
    alert(show_id);
    });
});
</code></pre>

<p>When I click the list items my alery shows a value of 0 when I am expecting a value of 8 or 13.</p>
