Could not open pop-up oAuth authentication in backbone

Question

I'm using this great library to make oauth authentication :

https://oauth.io/docs/mobiles

and by this code (written in router function) :

OAuth.initialize('FUxf14**YBrE');
//Using popup (option 1)
  OAuth.popup('instagram', function(error, result) {
    //handle error with error
    //use result.access_token in your API request
      console.log(error);
  });

This code should open a pop-up but console.log(error) tell me:

message: "Could not open a popup"

Why it can't open a pop-up?

Answer 1

The popup is probably blocked by the browser.

To prevent that, make the call to OAuth.popup only inside a click event handler.
