  • How to Get the Current Page’s URL into Flash
    7 years ago
    This little trick allows a Flash movie (swf) to find out the URL of the page in which it’s embedded. Javascript must be enabled for this to work. if the window.location.href.toString method doesn’t return a value then ExternalInterface.call will return null. Same thing happens when Javascript is disabled.
    1. // This little trick allows a Flash movie (swf) to find out the URL of the page in which it’s embedded.
    3. import flash.external.ExternalInterface;
    5. var pageURL:String =
    6.         ExternalInterface.call(‘window.location.href.toString’);
