If statement not triggering alert box
<p>I am trying to create a if statement that triggers a alert box if there is text in the div.</p>

<p>My Jsfiddle: <a href="http://jsfiddle.net/D7cPT/21/" rel="nofollow">http://jsfiddle.net/D7cPT/21/</a></p>

<p>My HTML:</p>

<pre><code>&lt;div id="post-preview"&gt;aasasdasd&lt;/div&gt;
</code></pre>

<p>MY JQUERY:</p>

<pre><code>$(document).ready(function() {
    // Bind it to some action.
    if{$('#post_body_html').html();) {
       alert('asdasda');
      }
});
</code></pre>
