我正在做一个从网站上抓取数据的项目。 html页面有一个选项可以在excel文件中保存数据。 input元素如下所示：

<input type="button" id="SaveXLS" class="func_button excel_sel" title="some title" onclick="doSave2XLS(1886);">

下面是提交表单的标题，我手动点击按钮后将数据保存到文件中。我想根据提交的表单和生成的数据以编程方式保存文件：

您想提交表单以生成数据，然后将此数据下载到Excel文件中吗？

使用jxl.jar创建Excel数据。（http://jexcelapi.sourceforge.net/）

例如，某些servlet文件中的代码。

public void doPost(HttpServletRequest request,HttpServletResponse response) throws Exception{

                response.reset();
                response.setContentType("application/vnd.ms-excel");
                response.setHeader("Content-Disposition",
                                "attachment;filename=filename.xls");
                WritableWorkbook wb = Workbook.createWorkbook(response
                                .getOutputStream());
                WritableSheet sheet = wb.createSheet("sheet1", 0);
                WritableCellFormat wcfFC = new WritableCellFormat(new     jxl.write.WritableFont(WritableFont.ARIAL, 10,
                                                 WritableFont.BOLD, false,
                                                 UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.RED));
//create headers
java.util.Enumeration names = request.getParameterNames();
int c=0;
while(names.hasMoreElements()){
String name = (String)names.nextElement();
String value = request.getParameterValue(name);
sheet.addCell(new Label(c, 0, name,wcfFC));
sheet.addCell(new Label(c, 1, value));
c++;
}
 wb.write();
 wb.close();
}
