hello after hours of search found script works iframe exept little problem never stops increases height no stop... here code add script @ page want iframe 

<script>   function alertsize(pixels){     pixels+=0;     document.getelementbyid('myiframe').style.height=pixels+"px";   } </script> <script type="text/javascript">   var myheight = 0;    setinterval(function(){     if(myheight != document.body.scrollheight){       myheight = document.body.scrollheight;       parent.alertsize(myheight);     }   },500); </script>
