我正在尝试将多个html表导出到单个文件excel（xls）它应该是这样的 Thanks Credit : How do I export multiple html tables to excel? HTML代码

<html>
<head>
    <title>JS to Excel</title>

</head>
<body>
    <table id="1">
        <tr><td>Hi</td></tr>
        <tr><td>Hey</td></tr>
        <tr><td>Hello</td></tr>
    </table>
    <table id="2">
        <tr><td>Night</td></tr>
        <tr><td>Evening</td></tr>
        <tr><td>Nite</td></tr>
    </table>

    <a id="dlink"  style="display:none;"></a>
    <input type="button" onclick="tablesToExcel(['1', '2'], ['first', 'second'], 'myfile.xls')" value="Export to Excel">
    <script src="~/Views/JS/JSExcel.js" type="text/javascript"></script>
</body>

和这样的Javascript

    var tablesToExcel = (function () {
    var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>'
    , templateend = '</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head>'
    , body = '<body>'
    , tablevar = '<table>{table'
    , tablevarend = '}</table>'
    , bodyend = '</body></html>'
    , worksheet = '<x:ExcelWorksheet><x:Name>'
    , worksheetend = '</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>'
    , worksheetvar = '{worksheet'
    , worksheetvarend = '}'
    , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
    , wstemplate = ''
    , tabletemplate = '';

    return function (table, name, filename) {
        var tables = table;

        for (var i = 0; i < tables.length; ++i) {
            wstemplate += worksheet + worksheetvar + i + worksheetvarend + worksheetend;
            tabletemplate += tablevar + i + tablevarend;
        }

        var allTemplate = template + wstemplate + templateend;
        var allWorksheet = body + tabletemplate + bodyend;
        var allOfIt = allTemplate + allWorksheet;

        var ctx = {};
        for (var j = 0; j < tables.length; ++j) {
            ctx['worksheet' + j] = name[j];
        }

        for (var k = 0; k < tables.length; ++k) {
            var exceltable;
            if (!tables[k].nodeType) exceltable = document.getElementById(tables[k]);
            ctx['table' + k] = exceltable.innerHTML;
        }

        //document.getElementById("dlink").href = uri + base64(format(template, ctx));
        //document.getElementById("dlink").download = filename;
        //document.getElementById("dlink").click();

        window.location.href = uri + base64(format(allOfIt, ctx));

    }
})();

它适用于一个excel文件中的2个表（xls） 我的问题是，如果我有1000张桌子怎么办？我如何使用DO或for循环来解决我的问题？ 我是学生，在编程方面真的很新，谢谢

最后，得到了朋友的帮助，并完成了:) HTML

<html>
<head>
    <title>JS to Excel</title>

</head>
<body>
    <table id="1">
        <tr><td>Hi</td></tr>
        <tr><td>Hey</td></tr>
        <tr><td>Hello</td></tr>
    </table>
    <table id="2">
        <tr><td>Night</td></tr>
        <tr><td>Evening</td></tr>
        <tr><td>Nite</td></tr>
    </table>

    <a id="dlink"  style="display:none;"></a>
<input type="button" onclick="tablesToExcel(array1, array2, 'myfile.xls')" value="Export to Excel">
    <script src="~/Views/JS/JSExcel.js" type="text/javascript"></script>
</body>

使用Javascript

var array1 = new Array();
    var array2 = new Array();
    var n = 2; //Total table
    for ( var x=1; x<=n; x++ ) {
        array1[x-1] = x;
        array2[x-1] = x + 'th';
    }

    var tablesToExcel = (function () {
        var uri = 'data:application/vnd.ms-excel;base64,'
        , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets>'
        , templateend = '</x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head>'
        , body = '<body>'
        , tablevar = '<table>{table'
        , tablevarend = '}</table>'
        , bodyend = '</body></html>'
        , worksheet = '<x:ExcelWorksheet><x:Name>'
        , worksheetend = '</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet>'
        , worksheetvar = '{worksheet'
        , worksheetvarend = '}'
        , base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
        , format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
        , wstemplate = ''
        , tabletemplate = '';

        return function (table, name, filename) {
            var tables = table;

            for (var i = 0; i < tables.length; ++i) {
                wstemplate += worksheet + worksheetvar + i + worksheetvarend + worksheetend;
                tabletemplate += tablevar + i + tablevarend;
            }

            var allTemplate = template + wstemplate + templateend;
            var allWorksheet = body + tabletemplate + bodyend;
            var allOfIt = allTemplate + allWorksheet;

            var ctx = {};
            for (var j = 0; j < tables.length; ++j) {
                ctx['worksheet' + j] = name[j];
            }

            for (var k = 0; k < tables.length; ++k) {
                var exceltable;
                if (!tables[k].nodeType) exceltable = document.getElementById(tables[k]);
                ctx['table' + k] = exceltable.innerHTML;
            }

            //document.getElementById("dlink").href = uri + base64(format(template, ctx));
            //document.getElementById("dlink").download = filename;
            //document.getElementById("dlink").click();

            window.location.href = uri + base64(format(allOfIt, ctx));

        }
    })();
