How to validate if an HTMLLIElement is hidden with jQuery
<p>I'm iterating through a variable called content, it contains several HTMLLIElement objects.
How can i use jQuery's or JavaScript's functions with this object?, what I'm trying to do is the kind of validation written in the commented code.</p>

<pre><code>    $.each(content, function(index, value){
         //if(!value.is(':hidden')){
              console.log(index + ' : ' + value);
         //}
    });
</code></pre>

<p>What I'm getting is </p>

<blockquote>
  <p>Uncaught TypeError: Object # has no method 'is'</p>
</blockquote>

<p>If I do <code>value.getAttribute('style');</code> I get <code>'display: none;'</code></p>
