Can I render multiple sources in EJS

问题

I am attempting to use data from 2 different sources, but render them on the same HTML page using EJS, JS and node. This is what I am trying..

app.set('view engine', 'ejs');
app.get('/', function(req, res) {
  res.render('index.ejs', { data: JSONdata })
  res.render('index.ejs', {data2: arrayData})
});

data is a JSON, data2 is an array. I have attempted to look up proper syntax for this exact process but cant seem to find anything.

Many thanks.

回答1:

You cannot render more than once to a single request.

But you could simply combine your JSON and array data and stringify it.

App.set('view engine', 'ejs');
app.get('/', function(req, res) {
  res.render('index.ejs', JSON.stringify({data2: arrayData, data1: JSONdata}))
});

Or simply assign both variables into a single object and parse it to the render function

var returnVals= JSON.stringify({data2: arrayData, data1: jsonData});

But if you want to show different types of data like:

SSCResult.find({username:username},function (err, results) {
  var username=req.user.username;
  var fullname =req.user.firstname+' '+req.user.lastname;
  if (err) return console.error(err);

  console.log(results);

  res.render('sscandhsc',{fullname:fullname,results});
  
});

SSCResult is a Schema. and results is like

[ { _id: 59f61fe2fec3cc7bf804f95e,
    examtype: 'HSC',
    username: '1',
    __v: 0,
    gpa: '5.00',
    institution: 'New Govt. Degree College, Rajshahi',
    passedyear: '2013',
    board: 'Rajshahi' },
  { _id: 59f6408efec3cc7bf804fc78,
    examtype: 'SSC',
    username: '1',
    __v: 0,

    gpa: '5.00',
    institution: 'Taragunia High School',
    passedyear: '2011',
    board: 'Jessore' },
  { _id: 59f656a9fec3cc7bf8050146,
    examtype: 'JSC',
    username: '1',
    __v: 0,
    gpa: '5.00',
    institution: 'Taragunia High School',
    passedyear: '2008',
    board: 'Jessore' } ]

so "results" and fullname is different types of json and you also can send it.

Lastly the upper(1) solution is also right form same type json file. Thank you. Hope it will help you. :)
