Question

I’m using Node.JS and Express web framework, I have a problem with the res.render()

I have this function:

exports.init = function(){

    return function(req, res, next) {   

        /* FORM CONTACT */
        if (req.body.contact){                      

            model.validateContact(function(e){              
                if (err) res.render('contacts', {'error': err})

                else {
                    model.sendContact(function(err){                                                
                        if (err) 
                            res.render('contacts', {'error': err})                              
                        else
                            res.redirect('/success')                                                        
                    })                                  
                }               
            })      

        }
        /* CONTACT */       

        res.render('contacts')
        console.log('after')
    }

}

Here I have a problem because res.render doesn’t exist from the init function(I refer to the res.render inside the inner functions (validateCOntact and sendContact) so the last res.render('contacts') will be always executed.

Why the script is continuing its process if I render a page? How is it possible that I can do res.render() more then one time?

Thank you

Try this:

exports.init = function() {

  return function(req, res, next) {
    /* FORM CONTACT */
    if (req.body.contact){
      model.validateContact(function(e) {
        if (err) {
          res.render('contacts', {'error': err});
        } else {
          model.sendContact(function(err) {
            if (err) {
              res.render('contacts', {'error': err});
            } else {
              res.redirect('/success');
            }
          });
        }
      });
    } else {
      /* CONTACT */
      res.render('contacts');
      console.log('after');
    }
  }
}
