Nodejs路由之间的数据传递

muri

　　实例是模拟登录页面提交表单，然后根据信息判断是否登录成功

　　login.js



var express =require('express');
var router =express.Router();
router.get('/',function(req,res,next){
res.render("login.jade");
});
module.exports = router;
　　login.jade



doctype html
html
head
meta(http-equiv="Content-Type",content="text/html; charset=utf-8")
title 添加数据页
body
h1 请填写你要发送的信息
form(action="/loginmsg",method="post")
input(name="msg",type="text",id="msg")
input(name="submit",type="submit")
　　loginmsg.js



var express =require('express');
var router =express.Router();
router.post('/',function(req,res,next){
var msg = req.body.msg;
if(msg){
res.render("loginmsg.jade",{msg:msg});
}
});
module.exports = router;
　　loginmsg.jade



doctype html
html
head
title 主页
body
div 你发送的信息为：#{msg}
　　app.js



var express = require('express');
var path = require('path');
var app = express();
var bodyParser = require('body-parser');
var login = require('./routes/login');
var loginmsg = require('./routes/loginmsg');
//模板引擎设置
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.static('public'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: true
}));
//设置路由
app.use('/',login);
app.use('/loginmsg',loginmsg);
app.listen(3000);
console.log("启动端口:3000");
