pass a javascript variable from an iframe to the parent frame
<p>So I have a variable in my iframe like so:</p>

<pre><code> &lt;script&gt;
var zipphone = "&lt;?= $phone ?&gt;";
 &lt;/script&gt;
</code></pre>

<p>Now I want to pass that variable to the parent frame after the iframe is loaded.  What is the simplest way to do that?</p>
