js导出table到excel同时兼容FF和IE示例_javascript技巧

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