title: Changing the placeholder text based on the users choice
body: <p>jQuery is permitted, but an HTML-only solution is preferred.</p>
  
  <p>I have a select box with a couple of options. When the user selects 'Name', I want the placeholder text 'Enter your name' to appear in the adjacent text-box.</p>
  
  <p>Likewise for 'ID' -> 'Enter your ID'.</p>
  
  <p>See <a href="http://jsfiddle.net/Uy9Y3/" rel="nofollow">http://jsfiddle.net/Uy9Y3/</a></p>
  
  <pre><code>&lt;select&gt;
      &lt;option value="-1"&gt;Select One&lt;/option&gt;
      &lt;option value="0"&gt;Name&lt;/option&gt;
      &lt;option value="1"&gt;ID&lt;/option&gt;
  &lt;/select&gt;
  &lt;input type="text"&gt;
  </code></pre>
  
  <p>This is a requirement by a client that I haven't been able to figure out.</p>
  
  <p>If it helps, the website is using the Spring framework.</p>
