title: jQuery detect when user uses SELECT element in form
body: <p>I want to be able to detect when the user has selected an option from a SELECT element in a form. I know what to do from there, but not sure about how to achieve the initial detection.</p>
  
  <pre><code>&lt;select id="mySelect"&gt;
      &lt;option&gt;1&lt;/option&gt;
      &lt;option&gt;2&lt;/option&gt;
      &lt;option&gt;3&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I would like the solution in JQuery if possible.</p>
