title: Set input value from current input textfield on change event
body: <p>I have a table with two input boxes.  A and B.  I enter something into input A (and also B) and I want it's value to automatically be set to whatever I type into it on change event.  Is this easy to do?  </p>
  
  <pre><code>&lt;tr&gt;    
   &lt;td&gt;&lt;input type="text" id="A1" name="A" value=""&gt;&lt;/td&gt;
   &lt;td&gt;&lt;input type="text" id="B1" name="B" value=""&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
