js导出table到excel，同时兼容FF和IE
前台调用（第一个参数是table的id)： <input value="导出" type="button" /> function toExcel(inTblId, inWindow) { if ($.browser.msie) { //如果是IE浏览器 try { var allStr = ""; var curStr = ""; if (inTblId != null && inTblId != "" && inTblId != "null") { curStr = getTblData(inTblId, inWindow); } if (curStr != null) { allStr += curStr; } else { alert("你要导出的表不存在！"); return; } var fileName = getExcelFileName(); doFileExport(fileName, allStr); } catch (e) { alert("导出发生异常:" + e.name + "->" + e.description + "!"); } } else { window.open('data:application/vnd.ms-excel,' + encodeURIComponent($('div[id$=divGvData]').html())); e.preventDefault(); } } function getTblData(inTbl, inWindow) { var rows = 0; var tblDocument = document; if (!!inWindow && inWindow != "") { if (!document.all(inWindow)) { return null; } else { tblDocument = eval(inWindow).document; } } var curTbl = tblDocument.getElementById(inTbl); if (curTbl.rows.length > 65000) { alert('源行数不能大于65000行'); return false; } if (curTbl.rows.length <= 1) { alert('数据源没有数据'); return false; } var outStr = ""; if (curTbl != null) { for (var j = 0; j < curTbl.rows.length; j++) { for (var i = 0; i < curTbl.rows[j].cells.length; i++) { if (i == 0 && rows > 0) { outStr += " \t"; rows -= 1; } var tc = curTbl.rows[j].cells[i]; if (j > 0 && tc.hasChildNodes() && tc.firstChild.nodeName.toLowerCase() == "input") { if (tc.firstChild.type.toLowerCase() == "checkbox") { if (tc.firstChild.checked == true) { outStr += "是" + "\t"; } else { outStr += "否" + "\t"; } } } else { outStr += " "+curTbl.rows[j].cells[i].innerText + "\t"; } if (curTbl.rows[j].cells[i].colSpan > 1) { for (var k = 0; k < curTbl.rows[j].cells[i].colSpan - 1; k++) { outStr += " \t"; } } if (i == 0) { if (rows == 0 && curTbl.rows[j].cells[i].rowSpan > 1) { rows = curTbl.rows[j].cells[i].rowSpan - 1; } } } outStr += "\r\n"; } } else { outStr = null; alert(inTbl + "不存在!"); } return outStr; } function getExcelFileName() { var d = new Date(); var curYear = d.getYear(); var curMonth = "" + (d.getMonth() + 1); var curDate = "" + d.getDate(); var curHour = "" + d.getHours(); var curMinute = "" + d.getMinutes(); var curSecond = "" + d.getSeconds(); if (curMonth.length == 1) { curMonth = "0" + curMonth; } if (curDate.length == 1) { curDate = "0" + curDate; } if (curHour.length == 1) { curHour = "0" + curHour; } if (curMinute.length == 1) { curMinute = "0" + curMinute; } if (curSecond.length == 1) { curSecond = "0" + curSecond; } var fileName = "设备状态" + curYear + curMonth + curDate + curHour + curMinute + curSecond + ".xls"; return fileName; } function doFileExport(inName, inStr) { var xlsWin = null; if (!!document.all("glbHideFrm")) { xlsWin = glbHideFrm; } else { var width = 1; var height = 1; var openPara = "left=" + (window.screen.width / 2 + width / 2) + ",top=" + (window.screen.height + height / 2) + ",scrollbars=no,width=" + width + ",height=" + height; xlsWin = window.open("", "_blank", openPara); } xlsWin.document.write(inStr); xlsWin.document.close(); xlsWin.document.execCommand('Saveas', true, inName); xlsWin.close(); }
