Loop through form checkboxes for dynamic list of checkboxes
<pre><code>elm = ('cbProducts' + suffix);
_ctl = document.forms[0].elements[elm];
</code></pre>

<p>This works when there are more than 1 checkbox in my list.
But when there are only 1, _ctl is undefined.</p>

<p>Would rather use jQuery if possible and have something like:</p>

<pre><code>elm = ('cbProducts' + suffix).trim();
_ctl = $("form :input #cbProducts*");
</code></pre>

<p>Next step is assigning length of _ctl (_ctl.length) but it is null for only 1 checkbox in the elements collection.</p>
