如何在Sails项目的ejs视图中访问nodeJS变量？

Question

My LoginController.js looks like this:

module.exports = {
  getAuthorizationLink: function (req, res) {
    res.send({
      authorization_link: sails.config.FACEBOOK_LOGIN_URL
    })
  }
}

I need to redirect to the authorization_link when a button is clicked

<div class="col-md-4 text-center">
  <button id="authenticate" class="btn btn-primary">Authenticate   Page</button>
  <script type="text/javascript">
    document.getElementById("authenticate").onclick = function () {
     ...
    };
  </script>
</div>

Here you are looking to mix server-side (EJS) & client-side JS code.

It is possible, makes sense to do sometimes but it is not clean. Once you understand you are doing this. Variable can be passed and accessed.

Using EJS, write JS code for client side eg

var auth_link = '<%= authorization_link %>';

this line will become something like below for client-side JS

var auth_link = 'https://fb.com/login';

Now you can use auth_link in client-side JS as required

Also, check res.view for responding with HTML page
