求教：页面报错

Question

"parent.fraRight"为空或不是对象，如何解决啊？？？

Answer 1

javascript报错吧!
parent.fraRight   parent不是一个对象,或者对象是空的

Answer 2

先看看当前页面有没有parent吧
alert()一下
有的话再看看有没有fraRight这个对象

Answer 3

我把涉及到的两个jsp文件的主要内容贴出来，大家帮帮忙！！！
ViewPaper.jsp代码如下：
function hideFraPaper(){
        parent.fraRight.rows = "0%,100%,0%,0%,0%,0%,0%";
        parent.fraPaper.window.location="/piccaudit/common/pub/Blank.html";
        parent.fraQuery.window.location="/piccaudit/common/pub/Blank.html";
        parent.fraQueryResult.window.location="/piccaudit/common/pub/Blank.html";
    }
  function previewPaper(){
   var fm = paperForm;
    parent.fraRight.rows="0%,10%,90%,0%,0%,0%,0%";
    fm.action = "/piccaudit/viewPreviewPaper.do";
    fm.target = "fraPaper";
    fm.submit();
  }
<logic:equal name="paperForm" property="auPaperPaperNature" value="1">
        <jsp:include page="/audit/project/view/ViewProcedure.jsp" />
</logic:equal>
<logic:equal name="paperForm" property="auPaperPaperNature" value="1">
    <table cellpadding="0" cellspacing="0" width="100%" cellspacing="1" cellpadding="5">
    <tr>
                <td align="center">
                    <img src="/piccaudit/common/images/butPrintControl.gif" value="打印预览" onclick="generateProcedureDiv();previewPaper();//hideFraPaper()" style="cursor:hand">
                </td>
    </tr>
    </table>
</logic:equal>
ViewProcedure.jsp部分代码如下：
function generateProcedureDiv()
   {
     var fm = paperForm;
     
     var strProcedureDivHtml = "";
     if(fm.auPaperPaperNature.value=="1")
     {
       for(i=1;i<fm.auProcedureProcedureNo.length;i++)
       {
         for(j=0;j<fm.auProcedureSubPaperIndex[i].length;j++)
         {
           strProcedureDivHtml = strProcedureDivHtml + "<input type='hidden' name='auPaperProcedureProcedureNo' value='" + fm.auProcedureProcedureNo[i].value + "'>";
           strProcedureDivHtml = strProcedureDivHtml + "<input type='hidden' name='auPaperProcedureSubPaperIndex' value='" + fm.auProcedureSubPaperIndex[i][j].value + "'>";
           strProcedureDivHtml = strProcedureDivHtml + "<input type='hidden' name='auPaperProcedureSubPaperVersion' value='" + fm.auProcedureSubPaperVersion[i][j].value + "'>";
         }
       }
//       alert(strProcedureDivHtml);
       tdProcedureDiv.innerHTML = strProcedureDivHtml;
     }
   }
点击“打印预览”按钮时调用的三个函数，大家看看，帮帮忙啊！！！

Answer 4

很简单，js报出‘不是对象’就说明parent.fraRight.rows 用法 出了问题
不能这样用。
换另一种办法吧
