IFrame根据内容自动适应高宽（同域）

src：必须和当前页在同域名下...

<iframe id="frame_content" src="/account/login"

width="390" height="350" allowtransparency="0" frameborder="0" marginwidth="0" marginheight="0"></iframe>

<script type="text/javascript">

function reinitIframe() {

var iframe = document.getElementById("frame_content");

var iframeWin = (iframe.contentWindow || iframe.contentDocument);

var winDoc = (iframeWin.document || iframeWin);

try {

iframe.width = Math.max(winDoc.body.scrollWidth, winDoc.documentElement.scrollWidth);

iframe.height = Math.max(winDoc.body.scrollHeight, winDoc.documentElement.scrollHeight);

} catch (ex) { }

}

$(function () {

window.setInterval("reinitIframe()", 200);

});

</script>
