更改前端NodeJs / Express / Jade中的routes变量的顺序

Question

Novice to NodeJS and Express but lets say I have this route for mywebsite.com/tournaments.

router.get('/tournaments', function (req, res) {
    TournamentController.getAllTournaments(function (err, docs) {
        if (err) {
            //render error
        } else {
            res.render('tournaments', {
                data: {
                    title: 'mysite',
                    command: 'tournaments',
                    user: req.session.user,
                    tournaments: docs
                }
            });
        }
    });
});

data.tournaments is an array of tournaments in order of their date. Lets say in the front end I have a select/option form where the user can choose date/prize/players as the order to sort the tournaments by. How can I sort the data.tournaments without having to call another route or refresh the page? I'm using Jade on the front end.

Answer 1

You can always sort them directly in the Browser via Javascript, either do it yourself or use a plugin like datatables .

If you don't wanna do that but do it on the server, you'll need an ajax call for that and a route that handles the sorting (based on the parameters you pass), and afterwards change the DOM according to the response. This goes without refreshing the page, but you'll need a route for that, or change the existing route and extend your controller to take optional parameters, something like

router.get('/tournaments/:sort?', function (req, res) {
    TournamentController.getAllTournaments(req.param('sort'), function (err, docs) {
        /* ... */
    });
});
