IFREAM 高度自适应

不支持跨域

<iframe src="http://www.baidu.com" frameborder="0" width="100%" scrolling="no"  onload="setIframeHeight(this)" id="pframe" name="pframe"></iframe>

<script>

function setIframeHeight(iframe) {
    if (iframe) {
        var iframeWin = iframe.contentWindow || iframe.contentDocument.parentWindow;
        if (iframeWin.document.body) {
        iframe.height = iframeWin.document.documentElement.scrollHeight || iframeWin.document.body.scrollHeight;
        }
    }
    };

</script>
