Can't using append and appendChild in a jQuery?
<p>I have a sample code:</p>

<pre><code>jQuery(document.body).append('&lt;div id="wrapper-1"&gt;&lt;/div&gt;').appendChild('&lt;div id="wrapper-2"&gt;&lt;/div&gt;');
</code></pre>

<p>How to get this result, how to ideas?</p>

<pre><code>&lt;div id="wrapper-1"&gt;
   &lt;div id="wrapper-2"&gt;&lt;/div&gt;
&lt;/div&gt;
</code></pre>
