If I assign the results of a jQuery selector to a variable, how can I further filter that?
<p>I have this:</p>

<pre><code>var startDate = $(".startdate");
</code></pre>

<p>..which should select all elements with the class 'startdate'.</p>

<p>I then try to do the following:</p>

<pre><code>startDate(".nodate").hide();
</code></pre>

<p>...to hide any elements with the 'nodate' css class but this fails.</p>

<p>I'm just guessing at syntax here, what silly mistake am I making?</p>

<p>Edit: the 'nodate' elements are not at the same level as the 'startdate' elements. I should have posted an XHTML snippet.</p>
