首先在js中写一个扩展类，主要的功能是把DataGrid中的数据转换成Excel的XML格式
'''将datagrid中的数据转换成Excel的XML格式'''
$.extend($.fn.datagrid.methods, {
getExcelXml: function (jq, param) {
var worksheet = this.createWorksheet(jq, param);
//alert($(jq).datagrid('getColumnFields'));
var totalWidth = 0;
var cfs = $(jq).datagrid('getColumnFields');
for (var i = 0; i < cfs.length; i++) {
totalWidth += $(jq).datagrid('getColumnOption', cfs[i]).width;
}
//var totalWidth = this.getColumnModel().getTotalWidth(includeHidden);

'''创建worksheet，将dataGrid的标题放到里面'''
createWorksheet: function (jq, param) {

var cellType = [];
var cellTypeClass = [];
'''var cm = this.getColumnModel();'''
var totalWidthInPixels = 0;

//将DataGrid的数据循环加入到Excel中
//Generate the data rows from the data in the Store
//for (var i = 0, it = this.store.data.items, l = it.length; i < l; i++) {

//alert(result.xml);
return result;
}
});
然后再新建一个一般处理程序
public void ProcessRequest(HttpContext context) {
'''给要7a686964616fe78988e69d83366下载的Excel赋一个初始的文件名'''
string fn = DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".xls";
'''获取前台传回来的值，应该是一个XML文件的内容''''
string data = context.Request.Form["data"];
'''将相对路径转换为绝对路径，数据，编码方式'''
File.WriteAllText(context.Server.MapPath(fn), data, Encoding.UTF8);'''如果是gb2312的xml申明，第三个编码参数修改为Encoding.GetEncoding(936)'''
context.Response.Write(fn);'''返回文件名提供下载'''
}
放在渐渐稳定了下来
因为excel数据写入涉及到字体，样式等多个方面，所以相对来说要复杂一些，可以参考下以下导出为excel方法代码：
import jxl.*;
import jxl.write.*;
import java.io.*;
import java.io.File.*;
import java.util.*;
public class excel
{
public static void main(String[] args)
{
String targetfile = "c:/out.xls";//输出的excel文件名
String worksheet = "List";//输出的excel文件工作表名
String[] title = {"ID","NAME","DESCRIB"};//excel工作表的标题
WritableWorkbook workbook;
try
{
//创建可写入的Excel工作薄,运行生成的文件在tomcat/bin下
//workbook = Workbook.createWorkbook(new File("output.xls"));
System.out.println("begin");
OutputStream os=new FileOutputStream(targetfile);
workbook=Workbook.createWorkbook(os);
WritableSheet sheet = workbook.createSheet(worksheet, 0); //添加第一个工作表
//WritableSheet sheet1 = workbook.createSheet("MySheet1", 1); //可添加第二个工作
/*
jxl.write.Label label = new jxl.write.Label(0, 2, "A label record"); //put a label in cell A3, Label(column,row)
sheet.addCell(label);
*/
jxl.write.Label label;
for (int i=0; i<title.length; i++)
{
//Label(列号,行号 ,内容 )
label = new jxl.write.Label(i, 0, title[i]); //put the title in row1
sheet.addCell(label);
}
//下列添加的对字体等的设置均调试通过，可作参考用
//添加数字
jxl.write.Number number = new jxl.write.Number(3, 4, 3.14159); //put the number 3.14159 in cell D5
sheet.addCell(number);
//添加带有字型Formatting的对象7a64e58685e5aeb9365
jxl.write.WritableFont wf = new jxl.write.WritableFont(WritableFont.TIMES,10,WritableFont.BOLD,true);
jxl.write.WritableCellFormat wcfF = new jxl.write.WritableCellFormat(wf);
jxl.write.Label labelCF = new jxl.write.Label(4,4,"文本",wcfF);
sheet.addCell(labelCF);
//添加带有字体颜色,带背景颜色 Formatting的对象
jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.RED);
jxl.write.WritableCellFormat wcfFC = new jxl.write.WritableCellFormat(wfc);
wcfFC.setBackground(jxl.format.Colour.BLUE);
jxl.write.Label labelCFC = new jxl.write.Label(1,5,"带颜色",wcfFC);
sheet.addCell(labelCFC);
//添加带有formatting的Number对象
jxl.write.NumberFormat nf = new jxl.write.NumberFormat("#.##");
jxl.write.WritableCellFormat wcfN = new jxl.write.WritableCellFormat(nf);
jxl.write.Number labelNF = new jxl.write.Number(1,1,3.1415926,wcfN);
sheet.addCell(labelNF);
//3.添加Boolean对象
jxl.write.Boolean labelB = new jxl.write.Boolean(0,2,false);
sheet.addCell(labelB);
//4.添加DateTime对象
jxl.write.DateTime labelDT = new jxl.write.DateTime(0,3,new java.util.Date());
sheet.addCell(labelDT);
//添加带有formatting的DateFormat对象
jxl.write.DateFormat df = new jxl.write.DateFormat("ddMMyyyyhh:mm:ss");
jxl.write.WritableCellFormat wcfDF = new jxl.write.WritableCellFormat(df);
jxl.write.DateTime labelDTF = new jxl.write.DateTime(1,3,new java.util.Date(),wcfDF);
sheet.addCell(labelDTF);
//和宾单元格
//sheet.mergeCells(int col1,int row1,int col2,int row2);//左上角到右下角
sheet.mergeCells(4,5,8,10);//左上角到右下角
wfc = new jxl.write.WritableFont(WritableFont.ARIAL,40,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.GREEN);
jxl.write.WritableCellFormat wchB = new jxl.write.WritableCellFormat(wfc);
wchB.setAlignment(jxl.format.Alignment.CENTRE);
labelCFC = new jxl.write.Label(4,5,"单元合并",wchB);
sheet.addCell(labelCFC); //
//设置边框
jxl.write.WritableCellFormat wcsB = new jxl.write.WritableCellFormat();
wcsB.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THICK);
labelCFC = new jxl.write.Label(0,6,"边框设置",wcsB);
sheet.addCell(labelCFC);
workbook.write();
workbook.close();
}catch(Exception e)
{
e.printStackTrace();
}
System.out.println("end");
Runtime r=Runtime.getRuntime();
Process p=null;
//String cmd[]={"notepad","exec.java"};
String cmd[]={"C:\\Program Files\\Microsoft Office\\Office\\EXCEL.EXE","out.xls"};
try{
