使Iframe能够了根据内容自动伸缩
?1.在IE中一定要有以下代码
iframe自动伸缩时还要加上
<meta http-equiv="X-UA-Compatible" content="IE=7" />
2.然后实现下面的函数，在iframe的load时候调用
<script type="text/javascript">
var iframeids=["test"]
var iframehide="yes"
function dyniframesize()
{
var dyniframe=new Array()
for (i=0; i<iframeids.length; i++)
{
if (document.getElementById)
{
dyniframe[dyniframe.length] = document.getElementById(iframeids[i]);
if (dyniframe[i] && !window.opera)
{
dyniframe[i].style.display="block"
if (dyniframe[i].contentDocument && dyniframe[i].contentDocument.body.offsetHeight)
dyniframe[i].height = dyniframe[i].contentDocument.body.offsetHeight;
else if (dyniframe[i].Document && dyniframe[i].Document.body.scrollHeight)
dyniframe[i].height = dyniframe[i].Document.body.scrollHeight;
}
}
if ((document.all || document.getElementById) && iframehide=="no")
{
var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
tempobj.style.display="block"
}
}
}
if (window.addEventListener)
window.addEventListener("load", dyniframesize, false)
else if (window.attachEvent)
window.attachEvent("onload", dyniframesize)
else
window.onload=dyniframesize
</script>
