Why do they use references instead of jQuery objects?
<p>In <a href="http://www.switchonthecode.com/tutorials/how-to-build-a-star-ratings-jquery-plugin" rel="nofollow">this</a> tutorial, they use containerElement.rating and starElement.rating for storing rating.</p>

<p>The question is : Why?? is it possible to use jQuery objects container and star like</p>

<p>container.rating and star.rating??</p>

<p>In their example, How does it work:</p>

<pre><code>star.click(function() {

        containerElement.rating = this.rating;//What does 'this' refer to?? Star or starElement??

        elements.triggerHandler("ratingchanged", {rating: this.rating});
      });
</code></pre>
