title: How to Copy Value from one Input Field to Another
body: <p>I have two input fields:</p>
  
  <pre><code>&lt;input type="text" id="one" name="one" /&gt;
  &lt;input type="text" id="two" name="two" /&gt;
  </code></pre>
  
  <p>I want to make it so that whatever that's typed into id one will automatically be put into id two.</p>
  
  <p>Any ideas on how to do this? Possibly javascript needed?</p>
