[Solved] Facebook Sample - Logged in & Logout

[HSLaw]

Hi,

I'm trying the sample on http://docs.telerik.com/platform/appbuilder/sample-apps/sample-facebook-api

My questions:

1. Logged in:
- How do we detect a user is already logged in?  So that we can hide the login button and show the logout button.

2. Logout:
Tried the codes to revoke permission & wipe the token (below). But it does not clear the logged in user fully.  When I click Login again, I no need to key in username & password and can just click OK to continue.  How can I logout so that I need to key in the username and password again?

01.$.oajax({
02.          type: "DELETE",
03.          url: "https://graph.facebook.com/me/permissions",
04.          jso_provider: "facebook",
05.          jso_allowia: true,
06.          dataType: 'json',
07.          success: function(data) {
08.              outputlog("Delete response (facebook):");
09.              outputlog(data);
10.          },
11.          error: function(e) {
12.              outputlog(e);
13.          }
14.      });
15.
16.      outputlog("wipe tokens");
17.     jso_wipe();

Thanks.

Hi,

1. You can detect when the user is logged in your app in the success handler of the login method.

2. I assume that the user is logged in the native FB app on the device which persists the token on the device. This is probably the main reason why the user logged in your app cannot log out it.

In addition, there is a forum thread about the issues in the pure JavaScript (as in the sample app) implementation of the plugin which you can consult here.

Let me know if further questions arise.

Hi,

Just a quick follow-up. I updated the forum thread here with a Telerik AppBuilder-compatible version of the Facebook Connect plugin and a sample app that uses it.

Let me know if this is helpful for you.

Best regards,
