Another Cross Domain iFrame Communication Technique

August 17, 2009 23:34 by admin

Recently I created a web page that hosted an iFrame. The contents of the iFrame were served from another domain. That content would use JavaScript to hide and show some HTML elements. As the iFrame’s content changed, I didn’t want scroll bars to appear or some of the content to be hidden (if I applied scrolling="no"). I could have just made sure the iFrame was big enough to contain the maximum content... but I wanted a more dynamic solution that made the iFrame appear more integrated with its parent page. I needed the parent page to adjust the size of the iFrame as the content size changed.
