[ 방법1 ]
적용가능 : IE 6 , IE 7
1. 넓이값과 높이값을 자동으로 해석하도록 하기
<script language="JavaScript" type="text/javascript">
<!--
function resizeFrame(iframeObj){
    var innerBody = iframeObj.contentWindow.document.body;
    var innerHeight = innerBody.scrollHeight + (innerBody.offsetHeight - innerBody.clientHeight);
    var innerWidth = innerBody.scrollWidth + (innerBody.offsetWidth - innerBody.clientWidth);
    iframeObj.style.height = innerHeight;
    iframeObj.style.width = innerWidth;
}
-->
</script>

<iframe src="filename.html" name="iframe1" frameborder="0" scrolling="no" onload="resizeFrame(this)"></iframe>

2. ㅤ넓이값은 고정하고, 높이값만 변동시키기
<script language="JavaScript" type="text/javascript">
<!--
function resizeFrame(iframeObj){
    var innerBody = iframeObj.contentWindow.document.body;
    var innerHeight = innerBody.scrollHeight + (innerBody.offsetHeight - innerBody.clientHeight);
    iframeObj.style.height = innerHeight;
}
-->
</script>

<iframe src="filename.html" width="넓이값" name="iframe_happyjung" frameborder="0" scrolling="no" onload="resizeFrame(this)"></iframe>

    if(doc.offsetHeight == 0){

        pageheight = doc.offsetHeight;
        parent.document.getElementById("contentFrame").height = pageheight+"px";
    }
}
window.onload = function(){
    init();
}
-->
</script>
<div id="ifrm">

    function resize() {
        frm.style.height = "auto"; // set default height for Opera
        contentHeight = frm.contentWindow.document.documentElement.scrollHeight;
        frm.style.height = contentHeight + 0 + "px"; // 23px for IE7
    }
    if (frm.addEventListener) {
        frm.addEventListener('load', resize, false);
