js導(dǎo)出格式化的excel 實(shí)例方法

更新時(shí)間：2013年07月17日 16:16:49 作者：

最常見(jiàn)的方式是使用js函數(shù)操作excle文件，這種方式可能因?yàn)g覽器不同，存在兼容性問(wèn)題。另一種簡(jiǎn)單方法就是導(dǎo)出一個(gè)excel能識(shí)別格式的xml文件，用excel打開(kāi)。

復(fù)制代碼代碼如下:

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 = "<?xml version=\"1.0\"?>\n";
    outStr = outStr + "<?mso-application progid=\"Excel.Sheet\"?>\n";
    outStr = outStr + "<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\"";
    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 + "<Worksheet ss:Name=\"Sheet1\">\n";
    outStr = outStr + "<Table ss:ExpandedColumnCount=\"30\">\n";
    var re = /^[0-9]+.?[0-9]*$/; //是否為數(shù)字
    if (inTbl != null) {
        for (var j = 0; j < inTbl.rows.length; j++) {
            outStr += "<Row ss:AutoFitHeight=\"0\">\n";
            for (var i = 0; i < inTbl.rows[j].cells.length; i++) {
                if (i == 0 && rows > 0) {
                    outStr += "<Cell><Data ss:Type=\"String\"></Data></Cell>\n";
                    rows -= 1;
                }
                var cellValue = inTbl.rows[j].cells[i].innerText;
                //小于12位數(shù)字用Number
                if(re.test(cellValue) && (new String(cellValue)).length < 11){
                    outStr = outStr + "<Cell><Data ss:Type=\"Number\">" + cellValue + "</Data></Cell>\n";
                }else{
                    outStr = outStr + "<Cell><Data ss:Type=\"String\">" + cellValue + "</Data></Cell>\n";
                }
                if (inTbl.rows[j].cells[i].colSpan > 1) {
                    for (var k = 0; k < inTbl.rows[j].cells[i].colSpan - 1; k++) {
                        outStr += " <Cell><Data ss:Type=\"String\"></Data></Cell>\n";
                    }
                }
                if (i == 0) {
                    if (rows == 0 && inTbl.rows[j].cells[i].rowSpan > 1) {
                        rows = inTbl.rows[j].cells[i].rowSpan - 1;
                    }
                }
            }
            outStr += "</Row>\n";
        }
    }
    else {
        outStr = null;
        alert("你要導(dǎo)出的表不存在！!");
        return;
    }
    outStr = outStr + "</Table>\n</Worksheet>\n</Workbook>";
    return outStr;
}
