jQuery each this
<pre><code>var slides = $(".promo-slide");
slides.each(function(key, value){
    if (key == 1) {
        this.addClass("first");
    }
});
</code></pre>

<p>Why do I get an error saying:</p>

<pre><code>Uncaught TypeError: Object #&lt;HTMLDivElement&gt; has no method 'addClass'
</code></pre>

<p>From the above code?</p>
