title: How can a ReactJS form submission access field values?
body: <p>I'm trying to make a form in ReactJS. <a href="https://facebook.github.io/react/docs/forms.html" rel="nofollow">https://facebook.github.io/react/docs/forms.html</a>, for instance, tells how to create a UI element, where changing the value of the element will trigger XYZ where the object on which an event occurs has access to the input and therefore its comments.</p>
  
  <p>Suppose that, within the same larger component, I have a TEXTAREA to enter data in, and a button to click to save it.</p>
  
  <p>How do I do things right so that a click to the button creates a new blank record and initializes its "description" field to the content of the TEXTAREA?</p>
  
  <p>Thanks,</p>
