Get element from JQuery object array
<p>See my code:</p>

<pre><code>var ths = $("#my_table table th");
if (ths.length &gt; 1) {
    var $th = ths[1]; // tried here plain 'var th' - still got error 
    th.find('#map_column_element_id'); // error here!
}
</code></pre>

<p>I get array of JQuery objects. Then I try to manage the second element as JQuery object. When I issue </p>

<pre><code>th.find(...)
</code></pre>

<p>I get <strong>TypeError: th.find is not a function</strong>. What am I doing wrong?</p>
