title: Autofill input with another input values
body: <p>I need to autofill an input field with the values of another input fields. So far I have this:</p>
  
  <pre><code>$("#field1, #field2").keyup(function(){
      $("#result").val(this.value);
  });
  
  &lt;input type="text" id="field1" name="field1" value="" &gt;
  &lt;input type="text" id="field2" name="field2" value="" &gt;
  
  //* to be filled with the values of the inputs above *// 
  &lt;input type="text" id="result" name="resut" value=""&gt;
  </code></pre>
