传递变量（服务器端/客户端）节点js

Just starting out with node, express and mongodb (mongoose) and this is what I am trying to do:

刚开始使用node,express和mongodb(mongoose),这就是我想要做的:

get parameters from jade file back to index.js via form ✔

通过表单✔从jade文件获取参数返回index.js

query the result in index.js ✔

在index.js中查询结果✔

and then return the result back to jade and display it ✖

然后将结果返回给jade并显示它✖

search.jade

form(action='/searchByTitle', method='get')
    input(type='text' name ='docTitle' placeholder='Title')
    input(type="submit" value = 'submit')

index.js

...
var Document = require('../models/document');
...

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

router.get('/searchByTitle', function(req, res){

    var title = req.param('docTitle');

    Document.find({ title: title }, function(err, doc) {
        if (err) throw err;
          console.log(doc);
        });         
});

in console.log(doc) I get a json object:

在console.log(doc)中我得到一个json对象:

[ { _id: 57b4725b3cd1c8a028a6f686,
    title: 'title123',
    category: 'category123',
    author: 'Anne',
    date: Thu Aug 25 2016 02:00:00 GMT+0200 (Central European Daylight Time),
    version: 1,
    file: 'test.txt',
    __v: 0 } ]

How do I pass that object back to search.jade so that i can display it on a page?

如何将该对象传递回search.jade以便我可以在页面上显示它?

I know I can do res.render('search', {doc: doc}); but by the time it is rendered, page is already being shown.. Do I have to change the routes somehow?

我知道我可以做res.render('search',{doc:doc});但是当它被渲染时,页面已经被显示了..我是否必须以某种方式改变路线?

Render the search.jade once again from searchByTitle.

再次从searchByTitle渲染search.jade。

router.get('/searchByTitle', function(req, res){

var title = req.param('docTitle');

Document.find({ title: title }, function(err, doc) {
    if (err) throw err;
      console.log(doc);
      res.locals.doc = doc;
      res.render('search');
    });         
});

Then use use the doc in search.jade.

然后使用search.jade中的doc。

form(action='/searchByTitle', method='get')
input(type='text' name ='docTitle' placeholder='Title')
input(type="submit" value = 'submit')
if(doc)
     //render the doc.
