For example, we have attached the swf using swfobject: ?View Code JAVASCRIPT1 2 3 4 5 6 7 8 9 <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("example.swf", "example", "702", "450", "8", "#ffffff"); so.addVariable("url", "http://www.example.com/click?id=12345&offerid=62244&type=10"); so.write("flash"); // ]]> </script> [...]
