title: Jquery + change label value without ID
body: <p>I have this label:</p>
  
  <pre><code>&lt;div id="edit-my-radios-0-wrapper" class="form-item"&gt;
  &lt;label class="option" for="edit-my-radios-0"&gt;
  &lt;input id="edit-my-radios-0" class="form-radio" type="radio" value="0"&gt;
  £25
  &lt;/label&gt;
  </code></pre>
  
  <p>Which I want to change the value of using JQuery.  Unfortunately I have no control over how it is created, and with an id, I'm not sure if it's even possible to target it.</p>
  
  <p>Does anyone have nay idea how to target it?</p>
  
  <p>Thanks in advance..</p>
