iframe框架高度自适应的实现

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>
