在javascript中获取for循环之外的java对象的值

Question

我通过从Java servlet作为对象获取Oracle的数据，在jsp中动态创建表。我的目标是通过将行num的值发送到另一个java servlet来编辑行。虽然我试图在下面的例子中打印alert的值，但它只恢复行中的最后一个值。谢谢你的帮助！

代码段＆amp; JavaScript的。目标是将crObject.getRefNum（）的值发送到java servlet。这是在jsp

中完成的

<div class="container">
  <table class="table">
    <th>Ref #</th>
    <th>CR #</th>
    <th>Imapcted Application</th>
    <th>Deployment Starts</th>
    <th>Deployment Ends</th>
    <th>Issue Description</th>
    <th>Approval Status</th>
    <th>Edit</th>


    <% 
CRDetails  crObject;
for (int i = 0; i < listLength; i++) 
{
    crObject = (CRDetails) Alldata.get(i);
    out.println("<tr><td>" + crObject.getRefNum() + "</td>" + "\n");
    out.println("<td>" + crObject.getCrNum() + "</td>" + "\n");
    out.println("<td>" + crObject.getAppName() + "</td>" + "\n");
    out.println("<td>" + crObject.getDeployStartTime() + "</td>" + "\n");
    out.println("<td>" + crObject.getDeployEndTime() + "</td>" + "\n");
    out.println("<td>" + crObject.getIssueDesc() + "</td>" + "\n");
    out.println("<td>" + crObject.getStatus() + "</td>" + "\n");
    pageContext.setAttribute("refNum",crObject.getRefNum());
//  pageContext.setAttribute("refNum",11);

%>
      <td><a editid="<%=crObject.getRefNum()%>" href="javascript:editRow()" target="_blank">Edit</a>${crObject.getRefNum()}</td>

      <!--<c:out value = '${refNum}' />-->
      <%    
}


    %>
