iframe自适应高度的多种方法方法小结
第一种方法：代码简单，兼容性还可以，大家可以先测试下。<script>
function SetWinHeight(obj)
{
var win=obj;
if (document.getElementById)
{
if (win && !window.opera)
{
if (win.contentDocument && win.contentDocument.body.offsetHeight)
win.height = win.contentDocument.body.offsetHeight;
else if(win.Document && win.Document.body.scrollHeight)
win.height = win.Document.body.scrollHeight;
}
}
}
</script>
<iframe width="778" align="center" height="200" id="win" name="win" onload="Javascript:SetWinHeight(this)" frameborder="0" scrolling="no" src="1.htm"></iframe>
第二种：经典代码 iFrame 自适应高度，在IE6/IE7/IE8/Firefox/Opera/Chrome/Safari通过测试。
<iframe src="http://www.sunhaibing.com/" id="iframepage" name="iframepage" frameBorder=0 scrolling=no width="100%" onLoad="iFrameHeight()" ></iframe>
<script type="text/javascript" language="javascript">
function iFrameHeight() {
var ifm= document.getElementById("iframepage");
var subWeb = document.frames ? document.frames["iframepage"].document : ifm.contentDocument;
if(ifm != null && subWeb != null) {
ifm.height = subWeb.body.scrollHeight;
}
}
</script>
或者下面这个
<script language="javascript" type="text/javascript">
function dyniframesize(down) {
var pTar = null;
if (document.getElementById){
pTar = document.getElementById(down);
}
else{
eval('pTar = ' + down + ';');
}
if (pTar && !window.opera){
//begin resizing iframe
pTar.style.display="block"
if (pTar.contentDocument && pTar.contentDocument.body.offsetHeight){
//ns6 syntax
pTar.height = pTar.contentDocument.body.offsetHeight +20;
pTar.width = pTar.contentDocument.body.scrollWidth+20;
}
else if (pTar.Document && pTar.Document.body.scrollHeight){
//ie5+ syntax
pTar.height = pTar.Document.body.scrollHeight;
pTar.width = pTar.Document.body.scrollWidth;
}
}
}
</script>
<iframe src ="/default2.aspx" frameborder="0" marginheight="0" marginwidth="0" frameborder="0" scrolling="auto" id="ifm" name="ifm" onload="javascript:dyniframesize('ifm');" width="100%">
</iframe>
