app.js

    app.use(express.favicon());
    app.use(express.logger('dev'));
    app.use(express.json());
    app.use(express.urlencoded());
    app.use(express.methodOverride());
    app.use(require('stylus').middleware(path.join(__dirname, 'public')));
    app.use(express.static(path.join(__dirname, 'public')));
    app.use(app.router);
    app.use(bodyParser.json());
    app.use(bodyParser.urlencoded({ extended: true }));
    app.use(express.bodyParser());

app.post('/detail', (req, res) => {    
//var data = res.json({ result: result });
console.log(req.body);
dbs.collection('slist').find({ name: req.body.name, age:1}).toArray((err, docs) => {
    if (err) return console.log(err)
    console.log(docs);
    res.render('detail', { title: 'Detail', year: new Date().getFullYear(), message: 'Detail of student', detail: docs});
}); 


})

I have tried all stuffs from other posts but I don't still get answers for it. I am creating a detail page for students and when I try it, req.body is always empty.(each table's td will have name and age and I want to send it when button clicked) Any ideas for me? Thank you for reading.

It seems that form action does not contain table elements.

just use styled html instead of table (such as div div div!)
