title: Find input button within a selected class div
body: <p>How could I use jquery to find out this button within a div with class name "blueheaderbar accordionButton on" then change button value to "hide it"</p>
  
  <pre><code>&lt;div class="blueheaderbar accordionButton selected" style="margin-top:20px"&gt;
              &lt;div class="floatleft"&gt;abc&lt;/div&gt;
              &lt;div class="floatright"&gt;&lt;input class="showhidebtn" type="button" value="Show Outlet" style="margin:6px 16px 0 0; width:86px" /&gt;&lt;/div&gt;
              &lt;div class="clear"&gt;&lt;/div&gt;
  &lt;/div&gt;
  
  &lt;div class="blueheaderbar accordionButton" style="margin-top:20px"&gt;
              &lt;div class="floatleft"&gt;abc&lt;/div&gt;
              &lt;div class="floatright"&gt;&lt;input class="showhidebtn" type="button" value="Show Outlet" style="margin:6px 16px 0 0; width:86px" /&gt;&lt;/div&gt;
              &lt;div class="clear"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
