jsp页面iframe高度自适应的js代码

<iframe id="agentFrame" name="agentFrame" src="/UploadFiles/2021-04-02/">

test.jsp如下：


<%@ page contentType="text/html;charset=GBK" language="java"%> 
<script> 
function pseth() { 
var iObj = parent.parent.document.getElementById('infoFrame'); 
iObjH = parent.parent.frames["infoFrame"].frames["agentFrame"].location.hash; 
iObj.style.height = iObjH.split("#")[1]+"px"; 
} 
window.onload=pseth(); 
</script>
