Question

I am working on a Facebook canvas iFrame application, and I`m going insane.
I am trying to check if a user is a fan of the page where the app is located, so that I can allow or disallow voting.

I use the following code:

function CheckFan() {
FB.init({
    appId: 'xxxxxxxxxxxxxxxxxxxxxxxxxx',
    status: true, // check login status
    cookie: true, // enable cookies to allow the server to access the session
    xfbml: true  // parse XFBML
});


FB.api({ method: 'pages.isFan', page_id: '145116742177104' }
    , function(resp) {
        if (resp) { $('#main_frame').show(); $('#non_fan').hide(); }
        else { $('#main_frame').hide(); $('#non_fan').show(); }
    });
}

This JS SDK is driving me up the wall, while calling the documentation “incomplete” is an insult to incompleteness.

Any input will be appriciated.

Thank you!

This has been deprecated by Facebook.
A new Graph API alternative will hopfuly be available by the time we need to deploy the app.

For now I use FQL:

FB.api({ method: 'fql.query', query: 'SELECT uid FROM page_fan WHERE uid= ' + user_id + ' AND page_id=145116742177104' },
    function(result) {
        if (result.length)
        { $('.main_frame').show(); $('#non_fan').hide(); } else { $('.main_frame').hide(); $('#non_fan').show(); }
    });
