title: How to uncheck programmatically a radiobutton after it was clicked manually?
body: <p>There are radiobuttons on a form :</p>
  
  <pre><code>...
  for ( $i = $data["figure"]["cnt"] / 2; $i &lt; $data["figure"]["cnt"]; $i++) {
      $tabFields[4]['html'] .= '
          &lt;td align="center"&gt;     
              &lt;input type="radio" id="fig_"'.$i.' name="fig_code" value="' . $data["figure"][$i]["fig_code"] . '" onchange="verifier_usage_figure('. $data["figure"][$i]["fig_code"] .')" /&gt;
          &lt;/td&gt;';
  ...
  </code></pre>
  
  <p>In the <code>verifier_usage_figure</code> function I want to uncheck the clicked radio when a certain condition is met. How to code that ?</p>
