jQuery determining if element exists on page
<p>How can I determine if an element exists on a page... for instance... </p>

<pre><code>$('select[name="modifier_option"]')
</code></pre>

<p>If that select box exists on the screen I need to validate it's value on the page to ensure it's value is > 0, but if it doesn't exist I don't need to worry about it.</p>
