Display HTML of iframe in alert only once iframe HTML has value?
<p>Here's what I want to do w/ jquery: </p>

<pre><code>var content=$("#iframe01").contents().find("#content").html();

if(/*VARIABLE CONTENT RETURNS NULL*/){check again for its value)

//BUT as soon as it has value, alert('content');
</code></pre>

<hr>

<p>I DON'T want to use .load or .ready. I think I need to use a loop of some kind… how do I do it? </p>
