如何在节点js中的另一个js文件中引用发布请求值？

Question

Long time, first time. I am new to learning node JS, Javascript, express, etc. and have been dealing with a problem for three days and counting. Hoping for some kind help here.

I have a view (called 'standings' view) where the user fills in an HTML form entering their username and bunch of team names.

• I handle the post request using express and save the data in mongodb
• The request contains a username field which can be referenced by 'req.body.username' inside the express app.post method.

What I am trying to do is capture this 'req.body.username' from the POST request and use it in another JS file (called 'thankyou.js') which would be the config file for a "thankyou" view. In other words, I am looking for a way to somehow reference the 'req.body.username' parameter directly without having to go back to the DB and in my "thankyou" view I want to say something like:

"Thank you" + <%= req.body.username %> + "for contacting us".

What would be the best approach to accomplish this? I have thought of and researched the following but not quite sure how to implement:

• Somehow export 'req.body.username' property in my standings JS file and require/reference it in the thankyou JS file.
• Using query strings to pass the 'req.body.username' in standings.js to the thankyou view.

Here is my express app.post method which handles the POST call from the user for the 'standings' view:

app.post('/standings', urlencodedParser, function(req, res){

var newStandings = standingsModel.update({ username: req.body.username}, req.body, {upsert: true}, function(err,data){
  if (err) throw err;

res.json(data);
})
});

Thanks in advance.

Answer 1

Are these REST calls? It looks like it, so I'm going to assume that this is stateless and you can't use session, right?

When do you send the user to the "thank you" page? If it's after submission, can you do a redirect instead of making everything an AJAX call?

I would take a look at this answer on passing data between routes/pages in ExpressJS. See if that offers any value to you. You might have to make some architectural changes.
