title: How can I access iframe elements with Javascript?
body: <p>I have a webpage where there is a textarea within a iframe. I need to read the value of this textarea from its child page JavaScript. Presently by using <code>window.parent.getelementbyID().value</code> in the JavaScript, I am able to fetch values of all controls in the parent page except the textarea within the iframe.</p>
  <p>The frame id and frame name in my parent page changes in runtime, hence we cannot use the frame id/frame name for reference.</p>
