js export formatted excel instance method_javascript skills

Copy code The code is as follows:

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 < inTbl.rows.length; j ) {
            outStr = "n";
            for (var i = 0; i < inTbl.rows[j].cells.length; 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 < 11){
                    outStr = outStr "" cellValue "n";
                }else{
                    outStr = outStr "" cellValue "n";
                }
                if (inTbl.rows[j].cells[i].colSpan > 1) {
                    for (var k = 0; k < inTbl.rows[j].cells[i].colSpan - 1; 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("The table you want to export does not exist!!");
return;
}
outStr = outStr "n n";
return outStr;
}

The above function was originally a function to export txt files. Save the excel file as an xml file, and you can get the xml file in what content format excel can recognize.
