问题
I created a facebook canvas. I'm looking for a way to change the canvas button from 'Go to app' to 'Login with Facebook' as shown on the attached pictures. Did some research but couldn't find anything on this matter. Any help would be appreciated. Thanks

One is an App that is embedded in Canvas: that's the "Go To App" one.
The other is a Website that is NOT embedded in a canvas, that's the "Login" one.
To change it, you'd need to use a custom login button to return the user to a holding webpage that is not in the Canvas. (You also need to set this "website" up in the Facebook Developers App settings page). From the landing webpage, you can kick the user back to the canvas once they've accepted the app permissions. Probably not worth the hassles for a button that no-one reads?

Just add a respone=token parameter in the URL and it shows "Login with facebook" and not "Go to app"
