问题描述

我正在尝试将多个 html 表导出到单个文件 excel (xls) 应该是这样的
谢谢信用：如何将多个 html 表导出到 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));

    }
})();

它适用于单个 Excel 文件 (xls) 中的 2 个表
我的问题是，如果我有 1000 张桌子怎么办？ 如何使用 DO 或 for 循环来解决我的问题？
我是一名学生，在编程方面真的很新，谢谢

这是我的工作解决方案：

首先为要导出的表指定相同的名称。

html

<a onclick="tableToExcel('orderTable', 'excel')"></a>

js

var tableToExcel = (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><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--><meta http-equiv="content-type" content="text/plain; charset=UTF-8"/></head><body><table>{table}</table></body></html>',
    base64 = function(s) {
        return window.btoa(unescape(encodeURIComponent(s)))
    },
    format = function(s, c) {
        return s.replace(/{(\w+)}/g, function(m, p) {
            return c[p];
        })
    }
return function(table, name) {
    if (!table.nodeType) {
        table = document.getElementsByName("orderTables");
    }
    var tableInnerHtml = "";
    for (var i = 0; i < table.length; i++) {
        //get tbody for once
        if (tableInnerHtml == "") {
            tableInnerHtml += table[i].innerHTML;
        } else {
            tableInnerHtml += table[i].tBodies[0].innerHTML;
        }
    }
    var ctx = {
        worksheet: name || 'Worksheet',
        table: tableInnerHtml
    }
    var a = document.createElement('a');
    a.href = uri + base64(format(template, ctx))
    a.download = name + '.xls';
    //triggering the function
    a.click();
}})()
