Javascript 单击submit按钮应该会显示一个包含目录中文件名列表的表

首先，我将选择年和月，点击下载按钮，它正试图运行下载脚本

然后，所有文件都将下载到此目录/usr/local/ndt files/year/month/usr/local/ndt files/2015/09。单击下载按钮，现在我想在表格中显示此给定目录的文件名。这里的目录名是动态的

我怎样才能做到这一点？谁能帮我一下吗

scriptformonth.sh文件中有什么内容？我已经编辑了代码，我认为用简单的JavaScript编写代码比执行这样的事情要容易得多。真正地这将只需要几行代码。目前脚本运行良好。现在我正在尝试在表中显示文件夹的所有文件名列表。如何实现这一点？这里的文件夹名是动态的。/usr/local/ndt文件在任何方向上都很常见，只有一年，每个目录的月份各不相同。我正在将所选的年份和月份写入一个文件views/downloadInput.txt。

router.post('/download', function (req, res, next) {

    var year = req.body.year;
    var month = req.body.month;
    var limit = req.body.files;


    var stream = fs.createWriteStream('views/downloadInput.txt');
    stream.once('open', function (fd) {
        stream.write(year);
        stream.write('\n');
        stream.write(month);
        stream.write('\n');
        stream.write(limit);
        stream.end();
    });

    child = exec("/usr/local/src/node-v0.10.35/nodeprograms/views/scriptformonth.sh",

    function (error, stdout, stderr) {

        if (!error) {

            console.log(stdout);

        } else {

            res.send(error);

        }
    });
});
