解决iframe框架页面自适应高度问题代码如下，需要注意的是框架引用页面一定要设置name属性，否则会不生效

方案一：

<iframe src="test.asp" width="100%" frameborder="0" scrolling="no" name="hj" id="hj"></iframe>

test.asp页面head间增加如下JS代码

<SCRIPT LANGUAGE="JavaScript">

function f_frameStyleResize(targObj){

 var targWin = targObj.parent.document.all[targObj.name];

 if(targWin != null) {

  var HeightValue = targObj.document.body.scrollHeight

  if(HeightValue < 600){HeightValue = 600}

  targWin.style.pixelHeight = HeightValue;

 }

}

function f_iframeResize(){

 bLoadComplete = true; f_frameStyleResize(self);

}

var bLoadComplete = false;

window.onload = f_iframeResize;

</SCRIPT>

方案二：备用

在主页面增加如下JS代码

<script type="text/javascript">
 var iframeids=["myblog"]
 var iframehide="yes"
 function dyniframesize()
 {
  var dyniframe=new Array()
  for (i=0; i<iframeids.length; i++)
  {
   if (document.getElementById)
   {
    dyniframe[dyniframe.length] = document.getElementById(iframeids[i]);
    if (dyniframe[i] && !window.opera)
    {
     dyniframe[i].style.display="block"
     if (dyniframe[i].contentDocument && dyniframe[i].contentDocument.body.offsetHeight)
      dyniframe[i].height = dyniframe[i].contentDocument.body.offsetHeight;
     else if (dyniframe[i].Document && dyniframe[i].Document.body.scrollHeight)
      dyniframe[i].height = dyniframe[i].Document.body.scrollHeight;
    }
   }
   if ((document.all || document.getElementById) && iframehide=="no")
   {
    var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
    tempobj.style.display="block"
   }
  }
 }

 if (window.addEventListener)
 window.addEventListener("load", dyniframesize, false)
 else if (window.attachEvent)
 window.attachEvent("onload", dyniframesize)
 else
 window.onload=dyniframesize

</script>
