title: jquery find all elements having a certain value
body: <p>When a user clicks on my radio button:</p>
  
  <pre><code>&lt;input type="radio" name="allselect" onClick="javascript: _select('none');" /&gt;
  </code></pre>
  
  <p>I need the function _select(param) to find every radio button with a value of param, so 'none' in this case, and click it. How can this be done in jquery?</p>
