首先,在你的主页面上必须包含以下这段javascript代码:
代码如下:
script language="Javascript"
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1]
//extra height in px to add to iframe in FireFox 1.0+ browsers
var FFextraHeight=getFFVersion=0.1? 16 : 0
function dyniframesize(iframename) {
var pTar = null;
if (document.getElementById){
pTar = document.getElementById(iframename);
}
else{
eval('pTar = ' + iframename + ';');
}
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+FFextraHeight;
}
else if (pTar.Document && pTar.Document.body.scrollHeight){
//ie5+ syntax
pTar.height = pTar.Document.body.scrollHeight;
}
}
}
/script
然后对于主页面用到iframe的地方添加代码:
iframe id="myTestFrameID"
onload="javascript:{dyniframesize('myTestFrameID');}"
marginwidth=0 marginheight=0 frameborder=0
scrolling=no src="/myiframesrc.php"
