一：前端
<t:dgToolBar title="Excel题库导入" icon="icon-search" onclick="questionImportListImportXls()"></t:dgToolBar>
<script type="text/javascript" charset="utf-8">
function questionImportListImportXls() {
openuploadwin(‘Excel题库导入‘, ‘xueBaQuestionController.do?upload‘, "questionImportList");
}
</script>
二：openuploadwin
/**
* 创建上传页面窗口
*
* @param title
* @param addurl
* @param saveurl
*/
function openuploadwin(title, url,name,width, height) {
gridname=name;
$.dialog({
content: ‘url:‘+url,
cache:false,
button: [
{
name: ‘开始上传‘,
callback: function(){
iframe = this.iframe.contentWindow;
iframe.upload();
return false;
},
focus: true
},
{
name: ‘取消上传‘,
callback: function(){
iframe = this.iframe.contentWindow;
iframe.cancel();
}
}
]
}).zindex();
}
三：上传页面
<%@ page language="java" import="java.util.*" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@include file="/context/mytags.jsp"%>
<!DOCTYPE html>
<html>
<head>

<t:base type="jquery,easyui,tools"></t:base>
</head>
<body style="overflow-y: hidden" scroll="no">
<t:formvalid formid="formobj" layout="div" dialog="true" beforeSubmit="upload">
