Question

我尝试使用JavaScript将HTML表格导出到Excel。然后我在打开Excel文件之前弹出这个：

“您要打开的文件，[file_name.xls]与其他文件不同格式比文件扩展名“
指定的格式

这是我的代码：

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, filename) {
        if (!table.nodeType) table = document.getElementById(table)
        var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }      
        var a = document.createElement('a');
        a.href = uri + base64(format(template, ctx));
        a.download = filename + '.xls';
        a.click();
    }
})()
