I am trying to fetch facebook user email for my app. But when I query, the email address is returned as undefined. I am not getting how to deal with it.
Here is my code-
<body>
<script>
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
if (response.status === 'connected') {
testAPI();
} else if (response.status === 'not_authorized') {
FB.login(function(response) {}, {
scope: 'email'
});
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
} else {
FB.login(function(response) {}, {
scope: 'email'
});
document.getElementById('status').innerHTML = 'Please log ' +
'into Facebook.';
}
}
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId: 'app id',
cookie: true, // enable cookies to allow the server to access
xfbml: true, // parse social plugins on this page
version: 'v2.1' // use version 2.1
});
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
(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'));
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
alert(response.name);
alert(response.email);
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML = 'Thanks for logging in, ' + response.name + '!';
});
}
</script>
<fb:login-button perms="email" autologoutlink="true" onlogin="checkLoginState();">
</fb:login-button>
<div id="status">
</div>
</body>

@Tobi this really saved my day :
FB.api('/me
Replaced by
FB.api('/me?fields=id,name,email,permissions', function(response) {
console.log(response.name);
console.log(response.email);
});
However, I don't understand why the scope of the following code (which is in the facebook documentation) isn't working
<fb:login-button scope="public_profile,email" onlogin="checkLoginState();">
You should use the scope attribute instead of perms in the Login Button, so the permission cannot be fetched. Try
<fb:login-button scope="public_profile,email" autologoutlink="true" onlogin="checkLoginState();">
</fb:login-button>
