javascript - Iframe height definition in IE 7 -


i have problem resizing iframe content in ie7. have external iframe 

<iframe id=fl_game src="my_iframe_page" frameborder=0   allowtransparency scrolling=no></iframe>

with width=100%, height=93%

and add page it. here page body

<div id="container"> <div id="game-box"> <div id="flashcontent">  </div> </div> </div> <script type="text/javascript"> swfobject.embedswf("<%=application.getcontextpath()%>/flash/<%= request.getparameter(param_game) %>/game.swf", "flashcontent", gamewidth, gameheight, "10.1", "/flash/expressinstall.swf", flashvars, params); </script>

on page add resize events.

if (window.addeventlistener) {     window.addeventlistener("load", resizegame, false);     window.addeventlistener("resize", resizegame, false); } else if (window.attachevent) {     window.attachevent("onload", resizegame);     window.attachevent("onresize", resizegame); } else {     window.onload = function() {resizegame();};     window.onresize = function() {resizegame();} }

here resizegame function

function resizegame(isieresize) {     var flash = document.getelementbyid('flashcontent');     var screen = screensize();     var width = screen.width;     var height = screen.height;     var left = 0;     var top = 0;     if (height * 1.5 >  width) {         height = width / 1.5     } else {         width = height * 1.5;     }     flash.width = width;     flash.height = height;     document.getelementbyid('flashcontent').style.width = width + 'px';     document.getelementbyid('flashcontent').style.height = height + 'px';     document.getelementbyid('flashcontent').style.top = '50%';     document.getelementbyid('flashcontent').style.left = '50%';     if (width < screen.width) {         left = (screen.width - width) / 2 + left;     }     if (height < screen.height) {         top = (screen.height - height) / 2;     }     document.getelementbyid('game-box').style.top = top + 'px';     document.getelementbyid('game-box').style.left = left + 'px'; }  function screensize() {     var w, h;     w = (window.innerwidth ? window.innerwidth : (document.documentelement.clientwidth ? document.documentelement.clientwidth : document.body.offsetwidth));     h = (window.innerheight ? window.innerheight : (document.documentelement.clientheight ? document.documentelement.clientheight : document.body.offsetheight));     return {width:w, height:h}; }

and here question: in ie7 function screensize() gives me wrong height on load. under other browsers , ie>7 function screensize() gives me correct height. that's why can't resize content properly. , when explicitly resize window, function screensize() starts give correct height. here screens before explicit resizing , after it. screen before resizing screen after resizing

screensize() gives strange height in ie7.

i ready add information find reason of situation. hope can me find out how define iframe height in ie7. useful.
