我能够从一个玉页发送数据到另一个，但我不知道如何在app.js的其他页面中使用它？(I am able to send a data from one jade page to other but I am not knowing how to use that in other page in app.js?)

我将变量'id'从索引页面发送到info / studs页面，它正在执行该部分，但我无法在app.js中使用该变量

extends layout block content .container .col-md-4 h2 Name a(href='../info/studs?id=#{user.id}') #{user.name} and app.js file containing app.get('/info/studs',function(req, res){ //Here I want to use variable 'id'

}）;

I am sending the variable 'id' from index page to info/studs page, and it is doing that part,but I am not able to use that variable in app.js

extends layout block content .container .col-md-4 h2 Name a(href='../info/studs?id=#{user.id}') #{user.name} and app.js file containing app.get('/info/studs',function(req, res){ //Here I want to use variable 'id'

});

最满意答案

查看req.query对象以获取更多信息。

要具体回答这个问题：

app.get('/info/studs',function(req, res){ //Here I want to use variable 'id' var id = req.query.id //You can now use the 'id' variable as you want. })

Take a look into the req.query object for more information.

To specifically answer the question:

app.get('/info/studs',function(req, res){ //Here I want to use variable 'id' var id = req.query.id //You can now use the 'id' variable as you want. })
