Append a dot to element every interval
<p>I have a simple 'processing' <em>dot wait... dot wait.. dot wait..</em> for when a user submits a form.</p>

<p>I thought this could be accomplished quite easily with something like</p>

<pre><code>&lt;h2&gt;Processing&lt;/h2&gt;
</code></pre>

<p>and</p>

<pre><code>$(document).ready(function(){

  setTimeout($('h2').append('.'), 500);

});
</code></pre>

<p>However it gets the first dot down, then throws back an error:</p>

<pre><code>Uncaught SyntaxError: Unexpected identifier
</code></pre>

<p>Where is my logic failing me on this one? What is the unexpected identifier?</p>
