title: Changing the id of an element using Prototype?
body: <p>Lets say I have an element like this:</p>
  
  <pre><code>&lt;input id="options_14_text" type="text" onchange="something()" name="options[14]" value=""&gt;
  </code></pre>
  
  <p>How could I change its id to options_15_text for example using Prototype?</p>
  
  <p>Thanks!</p>
