使用JSP与JavaScript实现Excel导出的简洁方案

<%@ page contentType="text/html; charset=GBK"%>
<%
  String context = request.getParameter("sContent");
  response.setHeader("Content-type","application/vnd.ms-xls");
  response.setHeader("Content-Disposition","attachment;filename=export.xls");
  response.setHeader("Expires","0");
  response.setHeader("Cache-Control", "no-cache, must-revalidate");
  response.setHeader("Pragma", "no-cache");
  out.print(context);
%>

<%@ page contentType="text/html; charset=GBK"%>
<% 
 String path = request.getContextPath();
%>
<html>
 <head>
 <script type="text/javascript">
  function exportData(){
  var html="<table><tr><td>星期一</td><td>星期二</td><td>星期三</td><td>星期四</td></tr>";
  html+="<tr><td>monday</td><td>tuesday</td><td>wednesday</td><td>thursday</td>";
  html+="</tr></table>";
  document.getElementByIdx_x_x("sContent").value=html;
  document.getElementByIdx_x_x("form1").submit();
  }
 </script>
 </head>
 <body>
 <iframe id="exeframe" name="exeframe" style="display:none">
 </iframe>
 <form id="form1" method="post" target="exeframe" action="export.jsp?ver=导出">
  <input type="hidden" id="sContent" name="sContent" value=""/>
 </form>
