.net把html页面表格转换成excel文件方法
一步:在页面前台加上如下代码
<a class="button_2" onclick="javaScript:window.printReport()" style="cursor:hand">打 印</a><Script language=网页特效> var winIndex = 0; //打印 function printReport() { var width = "600"; var height = "400"; var urlVar = "../Report/PmsAccidentStatisticsReportExcel.asp教程x?formyear=<%=_flag %>"; var top = (screen.availHeight - height) / 2; var left = (screen.availWidth - width) / 2; var feather = "toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=" + width + "px,height=" + height + "px,top=" + top + ",left=" + left + ",titlebar=no"; var t = window.open(urlVar, "pmsReport_Allpms19"+winIndex, feather); t.focus(); winIndex++; }</script>第二步: 新建PmsAccidentStatisticsReportExcel.aspx文件.这个页面用来输出Excel文件.所以这个页面根据传过来的参数得出全部所需要下载的数据
PmsAccidentStatisticsReportExcel.aspx前台代码 (主要是建一个Table其中的每个TD用<%=_formyear%>绑定后如的string字段,用Label控件不行)
