Hi:

I have a IFrame called "dataFrame". Does anybody know the difference between

document.getElementById('dataFrame').height

and

document.getElementById('dataFrame').Document.body .scrollHeight;

and

document.getElementById('dataFrame').style.height

function shrinkIFrame() {

var theFrame=document.getElementById('dataFrame');
var header,headerHeight,footer,navPrimaryMenu,navPrima ryMenuHeight,mainMenu2,iFrameHeight,mainMenu2Heigh t,wholeWindowHeight;
var totalHeight,differenceHeight;

if(theFrame){

theFrame.style.display="block"
if(theFrame.Document && theFrame.Document.body.scrollHeight)
{


header=parent.document.getElementById('Header2');
navPrimaryMenu=parent.document.getElementById('nav PrimaryMenu');
mainMenu2=parent.document.getElementById('mainMenu 2');

headerHeight = header.offsetParent.offsetHeight;
navPrimaryMenuHeight=navPrimaryMenu.scrollHeight;
mainMenu2Height=mainMenu2.scrollHeight;
wholeWindowHeight=document.body.offsetHeight;
iFrameHeight =theFrame.Document.body.scrollHeight;

totalHeight =headerHeight+mainMenu2Height+navPrimaryMenuHeight ;

differenceHeight = wholeWindowHeight - totalHeight;



//alert("differenceHeight: " + differenceHeight);

if (iFrameHeight > differenceHeight)
{
// 92 represent the row header, one row and the scrollbar
//alert("iFrameHeight > differenceHeight");
if (differenceHeight > 92)
{

theFrame.style.height=differenceHeight+ 'px';
}
else
{
alert("theFrame.height:"+theFrame.height+"theFrame .Document.body.scrollHeight:"+theFrame.Document.bo dy.scrollHeight);
alert("differenceHeight:"+differenceHeight+"theFra me.style.height:"+theFrame.style.height);

theFrame.height=theFrame.Document.body.scrollHeigh t;

}

}
else
{

theFrame.style.height = differenceHeight +'px';
}


}
if(theFrame.attachEvent){

theFrame.detachEvent("onload", readjustIframe)
theFrame.attachEvent("onload", readjustIframe)
}
}

}

Yours,

Frustrated
