关于取当前页面高义问题

Question

<script language="JavaScript">
window.onload=function()
{
document.all("test").height=test.document.body.scrollHeight;
}
</script>
<iframe name="test" src="abc.htm" frameborder="0"  marginheight="0"  marginwidth="0" width="100%" height="0" scrolling="no"> </iframe>

Answer 1

var  h  =  document.body.scrollHeight;  //刷新时这里取值为零------>var  h  =  iframe.document.body.scrollHeight;

Answer 2

var h = document.body.scrollHeight;
=>
var h = document.documentElement.scrollHeight;

Answer 3

var h = document.documentElement.scrollHeight;
试过,可是仍旧不行....

Answer 4

把以下代码加到引用页面，iframe会自动适应引用页面的高度
<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 < 540){HeightValue = 540} //不小于540
targWin.style.pixelHeight = HeightValue;
}
}function f_iframeResize()
{
bLoadComplete = true;
f_frameStyleResize(self);
}var bLoadComplete = false;
window.onload = f_iframeResize;
</script>
