javascript - Node.js undefined properties -

i'm trying create log in window. code simple.

var employees = {  	'1' : {  		firstname: '',  		lastname: '',  		login: 'qwerty',  		password: '12345',  	},  	'2' : {  		login: 'asdfg',  		password: '12345',  	},  };    app.post('/main', function(req, res) {  	if (!req.body) return res.sendstatus(400);  		console.log(req.body);  	for (var key in employees) {  		console.log(key['login']);  		console.log(key['password']);  		if ((key.login == req.body.login) && (key.password == req.body.password)) {  				res.render('main');  		} else {  			app.get('/', function(req,res) {  				res.send(createindexpage());  			});  		};  	};  });

why key.login , key.password return undefined? , why else block not run when if statement wrong?

look @ value of key is:

var employees = {    '1': {      firstname: '',      lastname: '',      login: 'qwerty',      password: '12345',    },    '2': {      login: 'asdfg',      password: '12345',    },  };    (var key in employees) {    console.log(key);  }

it property name (as string), not value of property.

console.log(employees[key]['login']); give looking for.
