title: Get option's value by text
body: <p>I have the following:</p>
  
  <pre><code>&lt;select name="dayRange" class="styled"&gt;
    &lt;option value="0"&gt;All day&lt;/option&gt;
    &lt;option value="1"&gt;Morning and day (8:00 - 18:00)&lt;/option&gt;
    &lt;option value="2"&gt;Evening(18:00 - 6:00)&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>How can I get <code>value</code> for specific text?<br>
  For example: return <code>value</code> for <code>All Day</code>.
  Thanks.</p>
