title: Changing the text in a dropdown
body: <p>If I have </p>
  
  <pre><code>&lt;select name="id[3]" id="attrib-3"&gt;
    &lt;option value="11"&gt;None&lt;/option&gt;
    &lt;option value="13"&gt;White ($4.72)&lt;/option&gt;
    &lt;option value="32"&gt;Black ($5.90)&lt;/option&gt;
    &lt;option value="12"&gt;Blue ($5.90)&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>and I want to change the prices based on another dropdown, what are my options?  (suppose I know in this case that option 13 should be 5.72, option 32 should be 6.90 and option 12 should be 6.90, for example).  I have the onchange on my first dropdown triggering, and I know how to get to attrib-3, but I'm not sure how to change the text fields for the dropdown.</p>
