title: Getting attribute value in event handling code for JQuery / CC selector
body: <p>I have a JQuery selector with some simple event handling attached.</p>
  
  <pre><code>jQuery('.ui-jqgrid-sdiv td[aria-describedby*="SUM"]').click(function(event) {alert('SUM=')}); 
  </code></pre>
  
  <p>Now, I want to find the exact value of the <code>aria-describedby</code> attribute. This could be say </p>
  
  <pre><code>SUM_1
