jquery 和 struts2 实现 excel的下载 100分哦！！
我用jquery 和struts2实现 excel的下载功能，思路是把表单内容存入excel中，首先我写了一个excel的xml格式的通用模板template.xls.txt代码如下

<?xml version="1.0"?>

<?mso-application progid="Excel.Sheet"?>

<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"

 xmlns:o="urn:schemas-microsoft-com:office:office"

 xmlns:x="urn:schemas-microsoft-com:office:excel"

 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"

 xmlns:html="http://www.w3.org/TR/REC-html40">

 <DocumentProperties xmlns="urn:schemas-microsoft-com:office:office">

  <LastSaved>2013-03-21T01:24:25Z</LastSaved>

  <Version>14.00</Version>

 </DocumentProperties>

 <OfficeDocumentSettings xmlns="urn:schemas-microsoft-com:office:office">

  <AllowPNG/>

  <RemovePersonalInformation/>

 </OfficeDocumentSettings>

 <ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel">

  <WindowHeight>8010</WindowHeight>

  <WindowWidth>14805</WindowWidth>

  <WindowTopX>240</WindowTopX>

  <WindowTopY>105</WindowTopY>

  <ProtectStructure>False</ProtectStructure>

  <ProtectWindows>False</ProtectWindows>

 </ExcelWorkbook>

 <Styles>

  <Style ss:ID="Default" ss:Name="Normal">

   <Alignment ss:Vertical="Bottom"/>

   <Borders/>

   <Font ss:FontName="宋体" x:CharSet="134" ss:Size="11" ss:Color="#000000"/>

   <Interior/>

   <NumberFormat/>

   <Protection/>

  </Style>

 </Styles>

 <Worksheet ss:Name="Sheet1">

  {$table}

  <WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel">

   <PageSetup>

    <Header x:Margin="0.3"/>

    <Footer x:Margin="0.3"/>

    <PageMargins x:Bottom="0.75" x:Left="0.7" x:Right="0.7" x:Top="0.75"/>

   </PageSetup>

   <Print>

    <ValidPrinterInfo/>

    <PaperSizeIndex>9</PaperSizeIndex>

    <HorizontalResolution>96</HorizontalResolution>

    <VerticalResolution>96</VerticalResolution>

   </Print>

   <Selected/>

   <Panes>

    <Pane>

     <Number>1</Number>

     <ActiveRow>1</ActiveRow>

     <ActiveCol>1</ActiveCol>

    </Pane>

   </Panes>

   <ProtectObjects>False</ProtectObjects>

   <ProtectScenarios>False</ProtectScenarios>

  </WorksheetOptions>

 </Worksheet>

</Workbook>

又写了个exportExcel.js代码如下

exportExcel={

		//定义excel方法

		//params: (sender&n
