title: Mootools each on childs
body: <p>I am working on a script what uses MooTools, and i want to select all input's in one element, but the problem is that I don't know the ID of the element, the element is a variable. (In The function is <code>formElement = $('form#aForm')</code>)</p>
  
  <p>Does someone know how I can use the each function on all input in one element. Now I am using: </p>
  
  <pre><code>$$('input').each(function(el) {
      alert(el.get('value'));
  });
  </code></pre>
  
  <p>But this script uses all elements in the document, and I want use only the elements in formElement. How is this possible?</p>
