JQuery .each() returns undefinied
<p>Hello i can´t find the mistake in my code. I am having two tables. The first one is only for the headers, because i didn´t found a solution to make the thead non scrollable. the Second one contains the content, but is empty when the side gets loaded. First the Code for both tables.</p>

<pre><code>            &lt;table width="100%"&gt;
                &lt;caption class="splitselection"&gt;
                    &lt;b&gt;Downloads&lt;/b&gt;
                &lt;/caption&gt;
                &lt;thead align="left"&gt;
                    &lt;tr&gt; 
                        &lt;th scope="col" width="36%"   align="left"          &gt;Dateiname           &lt;/th&gt;
                        &lt;th scope="col" width="32%"   align="left"          &gt;Fortschritt         &lt;/th&gt;
                        &lt;th scope="col" id="status" width="22%"align="left" &gt;Status              &lt;/th&gt;
                        &lt;th scope="col" width="10%" align="left"            &gt;Ordner &amp;ouml;ffnen  &lt;/th&gt;
                    &lt;/tr&gt;
                &lt;/thead&gt;
            &lt;/table&gt;
            &lt;div style="overflow:auto; height:115px;  width:100%" class="downloadFrame"&gt;
                &lt;table width="100%" id="download_table" align="center"&gt;
                    &lt;tbody align="left"&gt;
                    &lt;/tbody&gt;
                &lt;/table&gt;
            &lt;/div&gt;
</code></pre>

<p>so for now i want to catch every  element in the table with the content with this code: </p>

<pre><code>var interval = window.setInterval(function() {
    $('#download_table &gt; tbody &gt; tr').each(function() {
        alert($(this).find('td')[0].html);
    });
},5000);
</code></pre>

<p>I am creating a interval which checks a specific tablecell.</p>

<p>In my Alert i want to retrieve this tablecell, but my Alert in here return me "undefinied".
If i am just writing <code>alert($(this).find('td')[0]);</code> it return me HTML <code>htmlObjectTableCell</code>.</p>

<p>Without adding any tablerow, my interval does nothing. If i add a row, i am getting an alert. So for me there must be something wrong when i want to get the tablecell html</p>

<p>Yet i tried to use .html .val and .text, but i am getting the same result as before. </p>
