调用导出EXCEL，没能实现 具体应该怎么调用上面的JS方法导出EXCEL呢 导出EXCEL JQuery JQuery UI --------------------编程问答-------------------- 一直都是用后台代码的方式，还真没有用过JQ
关注一下。。 --------------------编程问答--------------------
还是后台导出方便些，用一些开源组件，像NPOI，教程自己搜
--------------------编程问答--------------------
没这样弄过，帮顶下
--------------------编程问答--------------------
估计你用jquery 弹出个页面后再关闭，要比这样实现简单多了，同样是无刷新的。
--------------------编程问答--------------------
用JS导出EXCEL在IE中一般是调用ActiveXObject，其他浏览器就不清楚了。JQUERY导出EXCEL没玩过，用后台代码实现这种功能更简单。
--------------------编程问答--------------------
http://www.iteye.com/problems/63968你可以参考一下，不过显而易见的是必须要调用ActiveXObject
--------------------编程问答-------------------- 有人指点下没 --------------------编程问答-------------------- 表单请求ACTION设为一个JSP页面，然后页面内部代码如下：
<%@ page contentType="text/html; charset=UTF-8" %>
<%
response.setHeader("Content-Type","application/force-download");
response.setHeader("Content-Type","application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment;filename=export.xls");
out.print(request.getParameter("exportContent"));
%>
应该就可以了
补充：.NET技术 , ASP.NET
