js导出数据为csv文件

function exportToCSV(data, filename) {
    // 将数据转换为 CSV 格式
    const csvContent = data.map(row => row.join(",")).join("\n");

    // 创建 Blob 对象
    const blob = new Blob([csvContent], { type: 'text/csv;charset=utf-8;' });

    // 创建下载链接
    const link = document.createElement("a");
    const url = URL.createObjectURL(blob);
    link.setAttribute("href", url);
    link.setAttribute("download", filename + ".csv");
    link.style.visibility = "hidden";
    document.body.appendChild(link);

    // 触发下载
    link.click();

    // 清理
    document.body.removeChild(link);
}

// 示例数据
const data = [
    ["Name", "Age", "Email"],
    ["John Doe", 30, "john@example.com"],
    ["Jane Smith", 25, "jane@example.com"]
];

// 导出 CSV 文件
exportToCSV(data, "example");

function escapeCSVField(field) {

    return field;
}

function sanitizeFilename(filename) {
