1、第一个适应高度的方案
<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>
<iframe src="/custom/job/question.do" scrolling="no" style="border: medium none; width: 710px; overflow: hidden;" id="iframepage" name="iframepage" onLoad="iFrameHeight()"> </iframe>
2、别人自适应的方案
