Find rows in a table where hidden field has value
<p>I have a table where every row has a hidden control as shown below</p>

<pre><code>&lt;input name="ID" id="ID" type="hidden"/&gt;
</code></pre>

<p>But some of them have values and others don't. How do I filter out the rows that have no value</p>

<p>I know it would be something like</p>

<pre><code>$('#myTable tr').filter(... ???
</code></pre>

<p>What I am trying to do is, get the rows where the hidden control has a value, then fetch certain controls and their values from those rows and post them using jquery ajax.</p>
