jQuery increment value of <span> tag
<p>I have a number in a span tag.  I need to get the value of the number in the span and then increment it inside jQuery.  I know how to do this for a text input - can this be done to a span tag?</p>

<p>SPAN tag</p>

<pre><code>&lt;span class="changeNumber"&gt; 33 &lt;/span&gt;
</code></pre>

<p>jQuery span selector</p>

<pre><code>var commentNumAppend = $(this).closest(".songContainer").find(".changeNumber");
</code></pre>
