Change Text in IFrame without JQuery : <p>Weave: <a href="http://kodeweave.sourceforge.net/editor/#f6d9a54288f17fb68a8b234ec364dc41" rel="nofollow">http://kodeweave.sourceforge.net/editor/#f6d9a54288f17fb68a8b234ec364dc41</a></p>

<p>I love JQuery, I do, but just for fun I'd like to learn how to write the following in pure/vanilla JS.</p>

</code></pre>
