如何将多个html表导出到excel？

问题描述：

我有一个有3个表格的网页，我想把它们全部导出到同一个excel文件中。我想要每张桌子在自己的表格，但把它们都放在同一张表上也是如此。经过一番搜索之后，我所看到的只是将一张表导出到一张excel表格中。

I have a webpage that has 3 tables and I'd like to export all 3 of them to same excel file. I'd like each table in its own sheet, but having them all on the same sheet is ok as well. After some googling, all I've seen is exporting one table to one excel sheet.

答

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));

    }
})();

而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(['1', '2'], ['first', 'second'], 'myfile.xls')" value="Export to Excel">
        <script src="~/Views/JS/JSExcel.js" type="text/javascript"></script>
    </body>
</html>

注意：这不适用于IE（数据太小错误）和Firefox两者表格放在同一张表上。

NOTE: this doesn't work on IE ('data too small' error) and on Firefox both tables are put on the same sheet.
