Pass a variable from javascript to ejs

Question

I want to use a variable which is declared in javascript file to a ejs file.

javascript:

var express = require(\'express\');
var app = express();

va         


        

Answer 1

The app.locals.myVar approach should work, so something must be getting in the way. But you could avoid using app.locals.myVar altogether and pass variables directly to your views with:

var express = require('express');
var app = express();

app.get('/', function(req, res) {
    var myVar = 1;
    res.render('testPage', { myVar : myVar });
});

The myVar variable should now be available to the "testPage" ejs file. Inside of it you could do:

<%= myVar %>

And see it output "1".

Lastly, make sure you have set the view engine to ejs:

app.set('view engine', 'ejs');

Otherwise it won't work.
