node.js render and send in same time

Question

How can i render jade and send some code after render without replace jade code by new code i sent it

here is example

var express = require('express');
var router = express.Router();
router.get('/user', function(req, res, next) {
//res.header("Content-Type", "application/json; charset=utf-8");
res.render('user', { title: 'Express' }); 




  //after render user jade i want to send some json to user
   res.contentType('application/json');
   res.send(json_code);

 });

When i run this code its replace the jade with json code ! how to solve it ?

you can either send JSON or HTML to client on one request. you cannot send both. — MoLow, Oct 18 '15 at 07:09
either you add the json data to the HTML page using a script tag (e.g http://stackoverflow.com/questions/8437295/jade-template-how-to-pass-concrete-object-to-pages), or the HTML page you send needs to initiate another request, to get the json data seperatly, either in a XHR, or in JSONP — MoLow, Oct 18 '15 at 07:12
Explain what your trying to accomplish, people can give you better advice this way. — tmcgoo, Oct 18 '15 at 07:46

Render the HTML page and inject the json_code to be used in a script tag:

JS:

router.get('/user', function(req, res, next) {
    var json_code = { 'hello': 'world' };
    res.render('user', { title: 'Express', data: JSON.stringify(json_code) }); 
});

HTML/JADE:

script
    var json_code = JSON.parse(#{data})
