title: How to get the datalist as an array?
body: <p>My HTML is a datalist with some suggestions to fill somethings.</p>
  
  <pre><code>&lt;datalist id="estados"&gt;
      &lt;option value="Acre" /&gt;
      &lt;option value="Alagoas" /&gt;
      &lt;option value="Amazonas" /&gt;
      ...
    &lt;/datalist&gt;
  </code></pre>
  
  <p>I want to get those as an array, so I can use it when the browser doesn't support this and enable with jQuery UI Autocomplete.</p>
  
  <pre><code>["Acre", "Alagoas", "Amazonas" ...]
  </code></pre>
