title: How can I select a radio button using jQuery without using its ID or value?
body: <p>So, I'm working within a CMS where I have custom code to select a level of money derived from calculated age. This code is applicable over a broad range of forms and would work fine except I cannot control the values or id's of the money levels. The hierarchy stays the same from form to form, as do the donation-level-label-containers, the id's and values however change to a new 5 digit number with every new iteration.</p>
  
  <pre><code>&lt;div class="donation-levels"&gt;
    &lt;div class="donation-level-container"&gt;
      &lt;div class="form-content"&gt;
        &lt;div class="donation-level-input-container form-input"&gt;
          &lt;div class="donation-level-label-input-container"&gt;
            &lt;input type="radio" name="level_installmentexpanded" id="level_installmentexpanded16025"
  value="16025"/&gt;

  <p>Using relative selectors or some other voodoo, can I set up a means by which to select these dynamically without having to change the ID every time it's applied to a new form?</p>
