Window.fbAsyncInit is not accessed

I have a script in file cshtml to use facebook API, but function window.fbAsyncInit is not called. How can I call this func?
This function show "flag 1" in console but flag 2 is not
<div onclick="likeb()">1</div>
function likeb() {
console.log("flag 1");
window.fbAsyncInit = function () {
FB.init({
appId: '295590887998480',
cookie: true,
xfbml: true,
version: 'v3.3'
});
FB.getLoginStatus(function (response) {
statusChangeCallback(response);
});
FB.login(function (response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
} else {
console.log('User cancelled login or did not fully authorize.');
}
}, { scope: 'user_likes,user_photos,user_link,user_posts,user_friends,publish_to_groups,manage_pages' });
FB.login(function (response) {
FB.api(
'/me/feed', 'post',
{ "message": "Hé lô mấy bạn ;)" },
function (response) {
console.log(response);
}
);
}, { scope: 'user_likes,user_photos,user_link,user_posts,user_friends,publish_to_groups,manage_pages' });
console.log("flag 2");
};
(function (d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) { return; }
js = d.createElement(s); js.id = id;
js.src = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
function statusChangeCallback(response) {
if (response.status === 'connected') {
console.log('Logged in and authenticated');
} else {
console.log('Not authenticated');
}
}
}
This function show "flag 1" in console but flag 2 is not

Get user email from facebook connect with SDK java script in v2.8

I can not retrieve the facebook e-mail address of a person who connects with the facebook login button. I use JDK java script in 2.8 version
<fb:login-button scope="public_profile,email" onlogin="checkLoginState();" auto_logout_link="true"></fb:login-button>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '<appId>',
xfbml : true,
version : 'v2.8'
});
FB.AppEvents.logPageView();
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_FR/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
function checkLoginState() {
FB.getLoginStatus(function(response) {
//console.log('Check login state');
//console.log(response);
statusChangeCallback(response);
});
}
function statusChangeCallback(response) {
if (response.status === 'connected') {
console.log('Connected');
testAPI();
} else if (response.status === 'not_authorized') {
console.log('Please log into this app');
} else {
console.log('Please log into Facebook.');
}
}
function testAPI() {
FB.login(function(response) {
if (response.authResponse) {
var access_token = response.authResponse.accessToken;
FB.api(
'/me',
{fields: 'id,email,cover,name,first_name,last_name,age_range,link,gender,locale,picture,timezone,updated_time,verified'},
function (response) {
console.log('response');
console.log(response);
}
);
} else {
console.log('User cancelled login or did not fully authorize.');
}
},{scope:'email'});
}
function testLogout() {
FB.logout(function(response) {
console.log(response);
});
}
</script>
I have all the information except the email. Can you help me please ?

Change:
FB.api(
'/me',
{fields: 'id,email,cover,name,first_name,last_name,age_range,link,gender,locale,picture,timezone,updated_time,verified'},
function (response) {
console.log('response');
console.log(response);
}
);
To:
FB.api(
'/me?fields=id,email,cover,name,first_name,last_name,age_range,link,gender,locale,picture,timezone,updated_time,verified',
function (response) {
console.log('response');
console.log(response);
}
);

Connecting Facebook on an application

Everytime I log out my account on Facebook itself, the connected account (same account) in the app also logs out. Is this expected?
I was hoping to come up with something like Hootsuite's functionalities, starting with Facebook first.
Here is my code.
<div id="fb-root"></div>
<script>
var app_id='{!#SETTINGS.facebook_api_key#value}';
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
if (response.status === 'connected') {
console.log('The user is connected.');
var fb_access_token = response.authResponse.accessToken;
console.log(fb_access_token);
rbf_setFieldValue("facebook_access_token", fb_access_token);
} else if (response.status === 'not_authorized') {
console.log('The user is not authorized.');
} else {
console.log('The user is not logged in.');
FB.login(function(response) {
console.log('Logging in.');
var fb_access_token = response.authResponse.accessToken;
console.log(fb_access_token);
rbf_setFieldValue("facebook_access_token", fb_access_token);
}, {scope: 'public_profile, manage_pages, publish_actions, user_groups'});
}
}
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : app_id,
cookie : true,
xfbml : true,
version : 'v2.1'
});
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>

Got it.
My mistake was I used FB.ui for posting to Facebook, and it requires a Facebook account to post.
The solution was to use FB.api and pass the user/page access token so that you can post without user login.
function postToSocialTimeline() {
try {
var obj = {
name: name,
description: description,
link: link,
picture: picture,
caption: caption,
message: "Test",
access_token: accessCode
};
function resp(response) {
console.log('Cancelled');
} //FB.ui(obj, resp);
FB.api('/me/feed', 'POST', obj, function(response) {
if (!response || response.error) {
console.log(!response ? 'error occurred' : response.error);
console.log('Error');
alert('Unable to post to Facebook!');
return;
} else {
alert('Requisition has been successfully posted!');
}
});
} catch (e) {}
}

How to login using Facebook account?

I have been through this link and tried the code.
I am doing the same thing but there is no response coming from Facebook. No popup (not blocked). My code is given below:
<div id="fb-root"></div>
<script>
// Additional JS functions here
window.fbAsyncInit = function() {
FB.init({
appId : 'myappid', // App ID
channelUrl : '//myurl/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.getLoginStatus(function(response) {
alert("Response");
alert("getloginstatus");
if (response.status === 'connected') {
// connected
} else if (response.status === 'not_authorized') {
// not_authorized
login();
} else {
// not_logged_in
login();
}
});
};
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
alert("Lodaed SDK");
}(document));
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
alert("Good to see you, " + response.name + ".");
});
}
function login() {
FB.login(function(response) {
if (response.authResponse) {
// connected
} else {
// cancelled
}
});
}
</script>
</div>
Please tell me what I am doing wrong. I yea, I have not any checkbox in

console.log("The person is logged into Facebook, but not your app.");
} else {
// The person is not logged into Facebook, so we're not sure if

Facebook Login infinite loop

I got a Problem with the Facebook Login on my page.
First I tried it with only FB.Login but then i get following message: "FB.login() called when user is already connected."
So I added FB.getLoginStatus But now it keeps loggin me in, in a infinite loop. Even if i'm logged (into my system) and without me clicking on the FB-Connect Button.
How can I achieve it to not log me in until I click the FB-connect Button?
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/fb_LT/all.js#xfbml=1&appId=198866780209581";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
window.fbAsyncInit = function() {
FB.init({
appId : "198866780209581", // App ID
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
var login = false;
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log('connected');
login=true;
$.ajax({
type: "POST",
url: "/?eID=login&modus=facebook&fb-login=1",
data: $(this).serialize(),
success: function(msg) {
console.log("LOGIN");
window.location.reload();
}
})
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
}
else{
FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
if(login===false)
{
alert('nicht connected');
}
});
} else {
console.log('User cancelled login or did not fully authorize.');
}
}, {scope: 'email'});
}});
// Additional initialization code here
};
</script>

The solution was to change the click function like this:
$(".fb-login-button").live("click", function() {
}
My final code looks like this:
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;

fjs.parentNode.insertBefore(js, fjs);

FB.init({
appId : "198866780209581", // App ID

xfbml : true,

});
var login = false;
$(".fb-login-button").live("click", function() {
FB.getLoginStatus(function(response) {
alert('hier 1');
if (response.status === 'connected') {
alert('connected');
console.log('connected');
login=true;
$.ajax({
type: "POST",
url: "/?eID=login&modus=facebook&fb-login=1",
data: $(this).serialize(),
success: function(msg) {
console.log("LOGIN");
window.location.reload();
}
})
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
}
else{
alert('im else');
FB.login(function(response) {
if (response.authResponse) {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
if(login===false)
{
alert('nicht connected');
}
});
