<p>How to set this.class to do something?
Now this.block doesn't work!</p>

<p><strong>HTML</strong></p>

<pre><code>&lt;div class="container"&gt;
    &lt;div class="block" &gt;#Product 01.&lt;/div&gt;
    &lt;img src="001.jpg" width="300"/&gt;
&lt;/div&gt;

&lt;div class="container"&gt;
    &lt;div class="block" &gt;#Product 02.&lt;/div&gt;
    &lt;img src="002.jpg" width="300"/&gt;
&lt;/div&gt;
</code></pre>

<p><strong>JS</strong></p>

<pre><code>$(".container").click(showDescription);

function showDescription() {
      $(this.block).slideToggle("slow");
}
</code></pre>
