How to provide (in IE and Firefox) a binary file download in a popup that closes

在parent页面打开child.jsp,  点击open时候会跳出空白页面和一个'打开和保存'对话框 .

解决方案如下:点击open时候, 下载action在父页面的iframe中加载, 利用的是window.open的  opener引用. 


parent.jsp

<iframe id='downloadiframe' style='visibility:hidden'></iframe>
<script defer="defer">
var cachePdf;

var download = function() {
      var doc = document.getElementById('downloadiframe').contentDocument || document.frames['downloadiframe'].document;
    doc.location = "DisplayStatementAction.do";
    cachePdf.close();
};
<logic:equal name="<%=subAppContextName%>" property="pdfCachePopUpSupported" value="true">
   <%
  VstmtContext vstmtContext = (VstmtContext)session.getAttribute("/apest/esonline/vstmt/VstmtContext");
  vstmtContext.setPdfCachePopUpSupported(Boolean.FALSE);
  %>
  cachePdf=window.open ('SetupDisplayStatementPop.do', 'PdfCachePopUp', 'height=200px,width=400px,top=200px,left=300px,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no, status=no');
</logic:equal>
</script>

child.jsp

1. <form method="POST" action="SetupDisplayStatementPop.do" onsubmit="processUnload()">
