title: How do I removeClass when I select specific option jQuery
body: <p>I'm new with jQuery and after 1 day of searching google I still have no solution.
  I need to remove <code>class="hidden"</code> when I select option with <code>value="test"</code> and add <code>class="hidden"</code> when I select another option without submit button. Please HELP.</p>
  
  <pre><code>&lt;select name="cars" class="help"&gt;
      &lt;option value="volvo"&gt;volvo&lt;/option&gt;
      &lt;option value="saab"&gt;saab&lt;/option&gt;
      &lt;option value="mercedes"&gt;mercedes&lt;/option&gt;
      &lt;option value="audi"&gt;audi&lt;/option&gt;
      &lt;option value="test"&gt;Test&lt;/option&gt;
  &lt;/select&gt;
  &lt;input type="checkbox" class="hidden"&gt;
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>$('.select option[value="test"]').clcik(function(){
      $(".hidden").removeClass();
  });
  </code></pre>
  
  <p>And a lot of different stuff (give an id to option or some tag) but still nothing :(</p>
