title: How to get scrollTop of an iframe
body: <p>jQuery's scrollTop returns null when window is an iframe. Has anyone been able to figure out how to get scrollTop of an iframe?</p>
  
  <p>more info:</p>
  
  <p>my script is running in the iframe itself, the parent window is on another domain, so I can't access the ID of the iframe or anything like that</p>
