title: Change an iframe's src from another html file?
body: <p>Well, I have my <code>radio elements</code> that update an <code>iFrame</code> with <code>js code</code>; and that works fine.</p>
  
  <p>Then I have my <code>button</code> below that creates an <code>iFrame</code> in a <code>HTML Division</code> that contains a bunch o' <code>buttons</code> in a list, my aim is to click one of these <code>buttons</code> in the <code>iFrame</code> then have that button to update the above <code>iFrame</code> (the one controlled by the <code>radio's</code>).</p>
  
  <p>How is this possible, can anyone help me? Thanks in advance. </p>
  
  <p>Note: I've tried using <code>&lt;link rel="import" href="parentpage.html"&gt;</code> to import its ID's (if it does that?) then tried using <code>JS</code> to update it that way, to no avail.</p>
