title: jQuery targeting aria attribute containing value
body: <p>In an HTML structure of :</p>
  
  <pre><code>&lt;div class="someclass" tabindex="0" aria-describedby="my-specified-action my-one-name"&gt;
  &lt;div class="someclass" tabindex="1" aria-describedby="my-specified-action my-two-name"&gt;
  &lt;div class="someclass" tabindex="2" aria-describedby="my-specified-action my-three-name"&gt;
  &lt;div class="someclass" tabindex="3" aria-describedby="my-specified-action my-four-name"&gt;
  &lt;div class="someclass" tabindex="3" aria-describedby="my-specified-action my-five-name"&gt;
  </code></pre>
  
  <p>I need to hide all elements that has an attribute <code>aria-describedby</code> containing my value ( for example <code>four</code> ), but leave all others untouched.</p>
  
  <pre><code>jQuery('div[aria-describedby*="four"]').hide()
  </code></pre>
  
  <p>of course, if I will do :</p>
  
  <pre><code>jQuery('div:not([aria-describedby*="four"])').hide()
  </code></pre>
  
  <p>it will hide ALL elements ( also the ones containing my target ..)</p>
  
  <p>for some reason, this is not working for me ,..</p>
  
  <pre><code>jQuery('div:not([aria-describedby^="four"])').hide()
  </code></pre>
  
  <p>what am I doing wrong ??</p>
