iframe自动调节大小问题--救命！
我页面中iframe的src可以选择的，但是由于每次选择的src页面的大小不确定，所以要不断地改变iframe的大小，并且我不愿意用滚动栏，我已经把iframe的滚动栏设为none了。
能不能写段代码让iframe根据所容纳页面的大小自动设置高度呢？
很急，救命！！！！！！！！！！
[解决办法]
主页面：
先 <iframe id= "frameName " src= 'aaa.htm '> </iframe>
内嵌页：aaa.htm
<body onload= "parent.document.getElementById( 'frameName ').height=document.body.scrollHeight; ">
[解决办法]
每查询出一次结果，加上这句
document.getElementById( 'frameName ').height=document.getElementById( 'frameName ').scrollHeight;
[解决办法]
<script language= "Javascript ">
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf( "Firefox ")).split( "/ ")[1];
//extra height in px to add to iframe in FireFox 1.0+ browsers
var FFextraHeight=getFFVersion> =0.1? 16 : 0 ;
function dyniframesize(iframename)
{
var pTar = null;
if (document.getElementById)
{
pTar = document.getElementById(iframename);
}
else
{
eval( 'pTar = ' + iframename + '; ');
}
if (pTar && !window.opera)
{
//begin resizing iframe
pTar.style.display= "block ";
if (pTar.contentDocument && pTar.contentDocument.body.offsetHeight)
{
//ns6 syntax
pTar.height = pTar.contentDocument.body.offsetHeight+FFextraHeight;
}
else if (pTar.Document && pTar.Document.body.scrollHeight)
{
//ie5+ syntax
pTar.height = pTar.Document.body.scrollHeight;
}
}
}
</script>
<iframe id= "contentframe " border= "0 " name= "content " frameSpacing= "0 " src= "aaa.html "
scrolling= "no " onload= "javascript:{dyniframesize( 'contentframe ');} " height= "100% "
allowTransparency> </iframe>
