JavaScript Ads modul

I need a JavaScript module that gets called like: <script type="text/javascript"> <!-- var p=[login to view URL]; if(p!='https:')p='http:'; [login to view URL]('<script type="text/javascript" src="'+p+'//[login to view URL]"></'+'script>'); //--> </script> The called js-file should create a 300x250 pixel winwdow where an iframe is placed (within a div with hidden overflow to prevent to show the scrollbars). The iframe should load a text that is given as a url.
