js导出格式化的excel 实例方法_javascript技巧

function getTableDataByXML(inTable, inWindow) {
var rows = 0;
//alert("getTblData is " + inWindow);
var tblDocument = document;
if (!!inWindow && inWindow != "") {
if (!document.all(inWindow)) {
return null;
}
else {
tblDocument = eval(inWindow).document;
}
}
var inTbl = tblDocument.getElementById(inTable);
var outStr = "\n";
outStr = outStr + "\n";
outStr = outStr + " outStr = outStr + " xmlns:o=\"urn:schemas-microsoft-com:office:office\"";
outStr = outStr + " xmlns:x=\"urn:schemas-microsoft-com:office:excel\"";
outStr = outStr + " xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\">\n";
outStr = outStr + "\n";
outStr = outStr + "\n";
var re = /^[0-9]+.?[0-9]*$/; //是否为数字
if (inTbl != null) {
for (var j = 0; j outStr += "\n";
for (var i = 0; i if (i == 0 && rows > 0) {
outStr += "\n";
rows -= 1;
}
var cellValue = inTbl.rows[j].cells[i].innerText;
//小于12位数字用Number
if(re.test(cellValue) && (new String(cellValue)).length outStr = outStr + "" + cellValue + "\n";
}else{
outStr = outStr + "" + cellValue + "\n";
}
if (inTbl.rows[j].cells[i].colSpan > 1) {
for (var k = 0; k outStr += " \n";
}
}
if (i == 0) {
if (rows == 0 && inTbl.rows[j].cells[i].rowSpan > 1) {
rows = inTbl.rows[j].cells[i].rowSpan - 1;
}
}
}
outStr += "\n";
}
}
else {
outStr = null;
alert("你要导出的表不存在！!");
return;
}
outStr = outStr + "\n\n";
return outStr;
}

上述函数原本是导出txt文件的函数。把excel文件另存为一个xml文件，就可得到excel能识别什么内容格式的xml文件。
