如何获取jsp页面表格中动态增加行的数据

使用 js 或者jquery

-----------------------------

但你动态增加行数据时，给当前增加的行 增加一个属性例如 name="addtr" <tr name="addtr"></tr>

当要获取时 可以使用js或jquery获取这种标记的tr就好

$(funciton(){

    $("tr [name='addtr']").each(function(){

        alert($(this).html())//增加的每一条tr的html数据

    })

})

jsp页面中可以通过动态生成excel的方式把table数据导入并保存。

以下是例子：

public static void crExcel(List list, String absoluteFileString)

throws Exception {

// 字体格式

WritableFont wfc0 = new WritableFont(WritableFont.ARIAL, 22,WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK)

WritableCellFormat wcfFC0 = new WritableCellFormat(wfc0)

wcfFC0.setAlignment(jxl.format.Alignment.CENTRE)

wcfFC0.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE)

wcfFC0.setBorder(Border.ALL, BorderLineStyle.THIN,jxl.format.Colour.GRAY_25)

// 表头字体

WritableFont wfc8 = new WritableFont(WritableFont.ARIAL, 12,WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK)

WritableCellFormat wcfFC8 = new WritableCellFormat(wfc8)

wcfFC8.setAlignment(jxl.format.Alignment.CENTRE)

wcfFC8.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE)

wcfFC8.setBorder(Border.ALL, BorderLineStyle.THIN,jxl.format.Colour.GRAY_25)

WritableFont wfc1 = new WritableFont(WritableFont.ARIAL, 10,WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK)

WritableCellFormat wcfFC1 = new WritableCellFormat(wfc1)

wcfFC1.setAlignment(jxl.format.Alignment.CENTRE)

wcfFC1.setBorder(Border.ALL, BorderLineStyle.THIN,jxl.format.Colour.GRAY_25)

// 创建excel

OutputStream os = new FileOutputStream(absoluteFileString)

String readPath = I18nMessages.getText("efine.excel.dir")

InputStream input = new FileInputStream(readPath

+ "FKBalanceReport.xls")

Workbook workbook = Workbook.getWorkbook(input)

WritableWorkbook book = Workbook.createWorkbook(os, workbook)

WritableSheet sheet = book.getSheet(0)

// 数据写入

Label label = null

// Title

//label = new jxl.write.Label(3, 0, "到期付款信息表", wcfFC0)

//sheet.addCell(label)

/*

* label = new jxl.write.Label(0, 3, "备注", wcfFC4)

* sheet.addCell(label)

*/

label = new jxl.write.Label(0, 0, "到期日", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(1, 0, "部门名称", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(2, 0, "币种", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(3, 0, "银行", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(4, 0, "金额", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(5, 0, "业务类型", wcfFC8)

sheet.addCell(label)

label = new jxl.write.Label(6, 0, "摘要", wcfFC8)

sheet.addCell(label)

sheet.setName("到期付款信息查询")

int j = 1

for (int i = 0i <list.size()i++) {

DNCM02 dto = (DNCM02) list.get(i)

label = new Label(0, i + j, CommonUtil.dateToStr(dto.getEndDay()),

wcfFC1)

sheet.addCell(label)

label = new Label(1, i + j, dto.getEndDeptName(), wcfFC1)

sheet.addCell(label)

label = new Label(2, i + j, dto.getCurrencyName(), wcfFC1)

sheet.addCell(label)

label = new Label(3, i + j, dto.getEndBankName(), wcfFC1)

sheet.addCell(label)

label = new Label(4, i + j, CommonUtil.formatString(dto

.getEndAmount().toString()), wcfFC1)

sheet.addCell(label)

label = new Label(5, i + j, dto.getEndTypeName(), wcfFC1)

sheet.addCell(label)

label = new Label(6, i + j, dto.getRemark(), wcfFC1)

sheet.addCell(label)

}

book.write()

book.close()

os.close()

}

然后指定excel的保存路径即可。

<script language="javascript">

iIndex = 0

var annex = 0

function getIndex()

{

iIndex = event.srcElement.parentElement.parentElement.rowIndex

return iIndex

}

function insertRow(iPos)

{

var otr=myTable.insertRow(annex)//插入一个tr

var ocell=otr.insertCell(0)//插入一个td

ocell.innerHTML="<input type=file size=20 name=annexValue(" + annex + ")>"

var ocell=otr.insertCell(1)//插入一个td

ocell.innerHTML=" <input type=button onclick=deleteRow(getIndex()) value='删除附件'>"

annex++

}

function deleteRow(iPos)

{

document.all.myTable.deleteRow(iPos)

annex--

}

</script>

<form name=myForm>

<a href="#" onClick="insertRow(0)">添加附件</a>

<table id="myTable"></table>

</form>

===================================

insertRow里的插入内容换成你自己的～

ie下可以用～firefox不行～
