FB.init is only for initializing the JavaScript SDK and there is no redirect_uri parameter as you can see in the docs. FB.login is for login, you can redirect with JavaScript after login:

FB.login(function(response) {
    if (response.authResponse) {
        //user just authorized your app
        window.location.href = 'xxx';
    }
}, {scope: 'email'});
