i have a problem , my Facebook login button does not work in some browsers like firefox or on mobile devices and the consolue shows a javascript error fb is not defined i tried fixing many times, read many blogs but failed , can someone sort the issue in my code here is the script i added in view . the error is at the last line of the script



 <script>

// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {

console.log(response);
if (response.status === 'connected') {


testAPI();

} else {
// The person is not logged into your app or we are unable to tell.

}
}

// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}

window.fbAsyncInit = function() {
FB.init({
appId : '***********************',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v3.1' // use graph api version 2.8
});

// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.

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 = "https://connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
//console.log('Welcome! Fetching your information.... ');
FB.api('/me?fields=name,email,first_name,last_name', function(response) {
console.log(response);
//document.getElementById('status').innerHTML = 'Thanks for logging in, ' + response.email + '!';
document.getElementById("fbuid").value=response.id;
document.getElementById("first_name").value=response.first_name;
document.getElementById("last_name").value=response.last_name;
document.getElementById("fb_email").value=response.email;
//if(response.email){
document.getElementById("fblogin").submit();
//}
});
}

document.getElementById('test').addEventListener('click', function() {
//do the login
FB.login(statusChangeCallback, {scope: 'email,public_profile',
return_scopes: true});
}, false);

  • Firefox blocks a lot of “tracker” scripts by default now, and the Facebook SDK is one of them.
