Java实现从网页表格导出CSV文件的例子

前台网页代码

<div class="row-fluid">

<div class="span12">

<div class="widget-box">

<div class="widget-title">

<h5>中奖信息列表</h5>

<div class="controls controls-row" style="padding-top:5px;">

<select id="export" name="export" class="span2 m-wrap" style="width:120px">

<option value="-1">导出文件</option>

<option value="XLS">导出Xls</option>

</select>

</div>

</div>

<div class="widget-content nopadding">

<table class="table table-bordered data-table table-striped with-check">

<thead>

<tr>

<th style="width:30px;">序号</th>

<th>用户ID</th>

<th>姓名</th>

<th>联系方式</th>

<th>第一关</th>

<th>时间</th>

<th>第二关</th>

<th>时间</th>

<th>第三关</th>

<th>时间</th>

</tr>

</thead>

<tbody>

</tbody>

</table>

</div>

</div>

</div>

</div>

前台对应js代码

$("#export").change(function() {

var v = $(this).val();

if(v == "XLS") {

window.open($ctx + '/prize/exportAsXls?firststep=' + $('#firststep').val()+"&secondstep="+$('#secondstep').val()+"&thirdstep="+$('#thirdstep').val());

}

$(this).val("-1");

});
