How can I select the row with an id that's depending on a javascript variable?
<p>I have a row with the <code>id="row_4"</code></p>

<p>I have a javascript variable <code>rownum</code> with a value of 4</p>

<p>How can I select using jQuery this element? I tried </p>

<p><code>$('#row_' + rownum)</code> </p>

<p>but this doesn't seem to work.</p>
