前端大概的樣式:

模板:?

?

效果:

HTML:

<span class="l" style="margin-left: 10px;"><a class="btn btn-primary radius" data-title="導出明細記錄" onclick="downloadExcelDetails()" href="#"><i class="Hui-iconfont">&#xe600;</i> 導出明細記錄</a> </span>

JS：

//導出Excel公共方法function downloadExcelDetails() {var logmin = $("#logmin").val();var logmax = $("#logmax").val();var compname = $("#compname").val();var area_name = $("#p_status").val();var d_type = $("#d_type").val();//條件判斷省略//.....window.location.href = "<%=basePath%>inspection/publicDownloadExcel.cyl?sDate="+ logmin +"&eDate="+ logmax +"&villageName="+ compname +"&area_name="+ area_name +"&d_type="+ d_type;}

控制層（?根據個人需求修改，代碼寫的有點亂，沒有什么設計模式，新手上路請多指教！）:
