<iframe src="test.html" scrolling="no" id="iFrame1" frameborder="0" width="475" onload="javascript:ReSizeiFrame(this);"></iframe>

内嵌框架iframe自适高度终极方案：

<iframe id="frame_content" src="iframe_b.html" scrolling="no" frameborder="0"
 onload="this.height=100"></iframe>

<script type="text/javascript">
function reinitIframe(){
var iframe = document.getElementById("frame_content");
try{

var bHeight = iframe.contentWindow.document.body.scrollHeight;
var dHeight = iframe.contentWindow.document.documentElement.scrollHeight;
var height = Math.max(bHeight, dHeight);一个ff 一个ie 取大值兼容
iframe.height =  height;
}catch (ex){}
}
window.setInterval("reinitIframe()", 200);//定时刷新重取 经测试对cpu 没啥影响
</script>
