jsp頁面iframe高度自適應的js代碼

 以下操作寫在body裡面，form表單外

1 2 3 4 5 6 7 8 9

<iframe id="agentFrame" name="agentFrame" src="" width="0" height="0" style="display:none;" ></iframe>  <script type="text/javascript">  function sethash(){  hashH = document.documentElement.scrollHeight; //擷取自身高度  urlC = "/test.jsp"; //設定iframeA的src  document.getElementById("agentFrame").src=urlC+"#"+hashH; //將高度作為參數傳遞  }  window.onload=sethash;  </script>

test.jsp如下：

1 2 3 4 5 6 7 8 9

<%@ 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>
