title: JQuery: how to exclude an option from .serialize()?
body: <p>I have a bunch of form elements in my form like this:</p>
  
  <pre><code>&lt;select id="sectionNumber" name="sectionNumber"&gt;
      &lt;option value="All"&gt;All&lt;/option&gt;
      &lt;option value="one"&gt;one&lt;/option&gt;
      &lt;option value="two"&gt;two&lt;/option&gt;
      &lt;option value="three"&gt;three&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I send this form as an AJAX request. </p>
  
  <pre><code>$.getJSON("myAction.action", $('#myForm').serialize(), processData);
  </code></pre>
  
  <p>If <strong>All</strong> is selected, is there an easy way to exclude the <code>sectionNumber=All</code> string from the <code>.serialize()</code> return value? I have a bunch of these, and not all of them have an <code>All</code> option.</p>
