EJS在2页之间共享数据

Question

Please tell me how to share data between 2 pages using EJS, if it's possible.

I'm getting json with some data on page1 and I need to share it on page2.

Right now I'm using another query in database(access data by link), but I want to reduce network traffic. Here I get the data:

router.get('/page1', function(req, res) {
   res.render('page1',{'result' : result} );
}

I want to click some button on page 1 and open page 2 with data from result[someIndex]

 router.get('/page2', function(req, res) {
       res.render('page2');
 }

Answer 1

1 - You can use Local Storage

2 - You can pass data with link

router.get('/page1', function(req, res) {
   res.render('page1',{'result' : result} );
}

In page 1 template ,

<a href="page2?name=value">link</a>

Then access it in page 2 like

app.get('/page2', function(req, res, next) {
   res.render('page2', {query : req.query.name});
});

3 - Pass data from root to both pages

app.get('/page1.js', function(req, res) {
  res.render('testPage', { myVar : ... });
});

app.get('/page2.js', function(req, res) {
  res.render('testPage', { myVar : ... });
});
