In jquery, how to get by class, but ignore if it contains another class?
<p>I am currently doing this:</p>

<p>var blah = $(".blah");</p>

<p>And this works how I want 99% of the time, but in one page I want this to be ignored.</p>

<p>Is it possible to add 'unless' or 'ignore if contains xxx class' also?</p>

<p>Meaning, get me all dom elements that contain the class 'blah', but only if it doesn't contain the 'ignoreme' class also?</p>

<pre><code>&lt;div id="blah ignoreme"&gt;&lt;/div&gt;
</code></pre>
