错误:“SCRIPT438:对象不支持属性或方法'btoa'”

尝试使用代码将HTML表导出到Excel时,在Internet Explorer中

:。

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]--></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) {

        $('#'+table+' .rowNumbers').remove();

            if (!table.nodeType) table = document.getElementById(table)
            var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }

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

        }
    })()

对于那些仍然在IE中的人而言,IE中的这种窘境可能是一种解决方法&lt; = 9?
