title: Call ajax load from a popup
body: <p>I'm trying to dynamically load html into a popup using ajax with this:</p>
  
  <p><code>$('body').load( new_url, function (responseText, textStatus, XMLHttpRequest ) { ... } );</code></p>
  
  <p>It works fine, but it doesn't load the html into the subwindow, it loads it into the opening window. If I have a reference to the subwindow "win", how can I do something like this:</p>
  
  <p><code>win.$( 'body' ).load...</code></p>
  
  <p>currently, that gives an error saying <code>win.$ is not a function</code>.</p>
  
  <p>Thanks!</p>
