        var line = datasource_1[_i];
        var i = 0;
        for (var _a = 0, line_1 = line; _a < line_1.length; _a++) {
            var item = line_1[_a];
            var it = item.replace(/"/g, '""');
            if (it.search(/("|,|\n)/g) >= 0) {
                it = '"' + it + '"';
            }
            content += (i > 0 ? ',' : '') + it;
            ++i;
        }
        content += newLine;
    }
    var link = document.createElement('a');
    link.setAttribute('href', 'data:text/csv;charset=utf-8,%EF%BB%BF' + encodeURIComponent(content));
    link.setAttribute('download', filename);
    link.style.visibility = 'hidden';
    document.body.appendChild(link);
    link.click();
    document.body.removeChild(link);
};
