问题:

I am having an issue with a script in express. I am calling a function that renders a view, on the success of another function. In this project I am utilizing angular, node, express, and ejs as view engine. When I render the view, I unfortunately receive an ejs error of the following:

ReferenceError: /Users/emilywfrancis/Desktop/nodejs-angularjs-sequelizejs/views/about.ejs:5  3| <html ng-app="app">  4| <meta charset="utf-8">  5| <link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/font-awesome/3.1.0/css/font-awesome.min.css" />  6| <% include header %>  7| <% include navbar %>   8| <body>   title is not defined

Here is the code:

exports.verifyusers= function(req, res) { models.user.find({ where: {   email: req.body.email,   password: req.body.password }  }).then(function(res, user) {     if(user == "user.name") { //if user exists in database         res.render('/about')     };  }); };

回答1:

Seems like the error is actually in the header file which proprely contains something like:

<%= title %>

I think changing changing it to the following will work:

<%= (typeof title != "undefined" ? title : "") %>

You need to give your title a value, if not already done. If it is done, then @andlrc answer is correct, but you still want to figure out why it is throwing an error. If not, it is bad practice.

In your server define a variable names title and give it a string. Then expose is to your view.

In this answer you find an example.
