title: How to remove the attribute "disabled" from input siblings when i click on a submit input
body: <p>i have this problem: i need to remove the "disabled" attibute from the siblings inputs of submit input. Here is the html:</p>
  
  <pre><code>&lt;td&gt;
  &lt;input type="hidden" value="2000000000002_STATUTO_07_10_2010.gif" name="nomeDocumento" disabled="true"&gt;
  &lt;input type="hidden" value="811ecdd0-65e9-49d6-8d9d-8b7c9d9b6407" name="UUID" disabled="true"&gt;   
  &lt;input type="submit" value="cancella" name="cancella"&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>i need a simple way using jquery to remove the disable attribute when i click on the submit.
  I tried:</p>
  
  <pre><code>$('input[name=cancella]').click(function(){
  $('this').prev().removeAttr('disabled');
  $('this').prev().prev().removeAttr('disabled');
  }
  </code></pre>
