</pre>
<p>We can determine the number of list items by calling <code>.size()</code>:</p>
<pre>alert('Size: ' + $('li').size());</pre>
<p>This will alert the count of items:</p>
<p><span class="output">Size: 2</span></p>
<p>The <a href="/length/">.length</a> property is a slightly faster way to get this information.</p>

<h3>Example:</h3>
<div id="entry-examples" class="entry-examples"><div id="example-0">
<h4><span class="desc">Count the divs. Click to add more.</span></h4>
<pre><code class="example demo-code">&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
&lt;style&gt;body { cursor:pointer; }
div { width:50px; height:30px; margin:5px; float:left; background:blue; }
span { color:red; }
&lt;/style&gt;
&lt;script src="http://code.jquery.com/jquery-latest.js"&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;span&gt;&lt;/span&gt;
&lt;div&gt;&lt;/div&gt;
&lt;script&gt;$(document.body).click(function () { $(document.body).append($("&lt;div&gt;"));
var n = $("div").size();
$("span").text("There are " + n + " divs." + "Click to add more.");}).click(); // trigger the click to start&lt;/script&gt;
&lt;/body&gt;
&lt;/html&gt;</code></pre>
