|
|
<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>
