rt,以下为iframe自适应高宽实现关键代码

///控制代码
<script type="text/javascript">
function reinitIframe(){
var iframe = document.getElementById("iframe1");
try{
var bHeight = iframe.contentWindow.document.body.scrollHeight;
var dHeight = iframe.contentWindow.document.documentElement.scrollHeight;
var height = Math.max(bHeight, dHeight);
iframe.height =  height;
}catch (ex){}
}
window.setInterval("reinitIframe()", 200);
</script>

 ///iframe标签

<iframe src="/Product/ifPro.aspx" id="iframe1" frameborder="0" scrolling="no" width="100%" onload="this.height=100"></iframe>
