title: identify select drop-down text using jquery $(this)
body: <p>I've got several select elements on a page e.g.</p>
  
  <pre><code>&lt;select class="dd" id="dropdown1"&gt;
      &lt;option value="123"&gt;Option A&lt;/option&gt;
      &lt;option value="234"&gt;Option B&lt;/option&gt;
  &lt;/select&gt;
  &lt;select class="dd" id="dropdown2"&gt;
      &lt;option value="456"&gt;Option C&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>etc etc</p>
  
  <p>I would like to use jquery's $(this) to identify which of the several drop-downs have been selected and return their textual value.</p>
  
  <p>I can use something like:</p>
  
  <pre><code>$("#dropdown1 :selected").text() 
  </code></pre>
  
  <p>To return a specified entry but when I try to add $(this) into the mix it doesn't work.
  Where am I going wrong?</p>
