title: jquery function on dropdown select
body: <p>I need to run a jquery function if a certain dropdown option is selected.</p>
  
  <pre><code>&lt;select name=dropdown size=1&gt;
      &lt;option value=1&gt;option 1&lt;/option&gt;
      &lt;option value=2&gt;option 2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I have the commands in the function ready, Im just not sure on how to make it so if option 2 is currently active in the dropdown, then run the function.</p>
  
  <p>(dropdown doesnt have a submit button, i want it ran when the user highlights the option)</p>
