Javascript 如何将数据从表单传递到路由器

我不熟悉java脚本和

node.js

；以防出现错误。请原谅我

我正在尝试编写一个简单的

Node.Js

服务器端应用程序

我在这里想要实现的是。在视图上，我有一个文本框和一个提交按钮。当我通过提交按钮时。写在文本框中的数据应该传递给路由器（

index.js

），路由器将对其进行处理

请看下面我的代码

查看代码

extends layout

block content
  h1= title
  form#formReadCSV(name="readCSVFile",method="post",action="/readCSVFile")
      input#inputCompleteCSVPath(type="text", placeholder="Complete Path" name="fileCSV")
      button#btnOpenFile(type="submit") Submit 


router(index.js)

---

现在按下提交按钮。这是一种无法到达路由器的方式。我得到下面的错误

csv is not defined

有没有什么方法可以调试

node.js

问候,， Rajesh安装模块csv

npm install ya-csv

将其添加到代码中

var csv = require('ya-csv');

例如：

模块

npm install ya-csv
npm install multer

形式

JS

谢谢你，亚历山大，这很有帮助。

npm install ya-csv
npm install multer

form#formReadCSV(name='readCSVFile', method='post', action='/readCSVFile', enctype='multipart/form-data')
  input#inputCompleteCSVPath(type='file', placeholder='Complete Path', name='fileCSV')
  button#btnOpenFile(type='submit') Submit 

var express = require('express');
var app     = express();
var router  = express.Router()
var csv     = require('ya-csv');
var multer  = require('multer');

app.set('view engine', 'jade');
app.set('views', __dirname + '/views');

app.use(multer({ dest: './uploads/'}))

router.get('/', function (req, res) {
  res.render('index');
});

router.post('/readCSVFile', function (req, res) {
  var reader = csv.createCsvFileReader(req.files.fileCSV.path, {'separator':',', 'quote':'"', 'escape':'"'});

  reader.addListener('data', function (data) {
    console.log(data);
  });

  reader.addListener('end', function() {
    res.send('File was processed');
  });
});

app.use('/', router);
app.listen(3000);
