让iframe自适应高度,下面是实现的源码:
<div id="leamain">
<iframe src="#" marginheight="0" marginwidth="0" frameborder="0" scrolling="no" width="765" height=100% id="iframepage" name="iframepage" 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>
</div>
以上亲测,ie、火狐、谷歌等浏览器均没问题,希望对你有用。
