title: JavaScript - Detecting Scrollbars in a Cross-Domain Iframe?
body: <p>I'm loading a cross-domain page (that I have no control over) into an iframe.</p>
  
  <p>I want to know if this results in a scrollbar appearing in the iframe on my page or not.</p>
  
  <p>I'm getting the impression that this just cannot be done (in Firefox at least), through any kind of direct detection or clever deduction, due to cross-domain security policies.</p>
  
  <p>Please only answer this question if you have direct experience successfully doing this yourself -- or trying everything and giving up.</p>
  
  <p>(Those other discussions you want to refer me to don't work for cross-domain iframes with no control over the embedded page. And if you think jQuery must have something for this, please test it out first yourself to make sure.)</p>
  
  <p><del>TIA -- I don't have an SO account to respond to your answers.</del> (do now)</p>
