FB is not defined javascript

This would be correct, you need to use FB after the JS SDK is initialized. That being said, you definitely don´t want to call FB.api in an infinite loop, so i removed that part:
<script>
function init() {
FB.api(
'/l214.animaux',
{"fields":"fan_count"},
function(response) {
alert(response.fan_count);
}
);
}
window.fbAsyncInit = function() {
FB.init({
appId : 'your-app-id',
xfbml : true,
version : 'v2.5'
});
init();
};
(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>
Make sure you run this from an actual server, don´t just open your HTML files in a browser without at least a local server.

I got this error because I write the init code in an independent js file, so, of course FB
is not defined, because it should be window.FB
.
my code:
class FacebookUtil {
static init() {
// comes from https://developers.facebook.com/docs/javascript/quickstart
// notice FB should be window.FB
window.fbAsyncInit = function() {
window.FB.init({
appId : '...',
autoLogAppEvents : true,
xfbml : true,
version : 'v2.10'
});
window.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_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
}
static login() {
window.FB.login(...)
}
}

I've a problem with FB JS SDK.
I'm trying to do a request to get the fan_count of a facebook page node.
Here is my code from my html file into the body :
<script> window.fbAsyncInit = function() { FB.init({ appId : 'your-app-id', xfbml : true, version : 'v2.5' }); }; (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>
And when I'm using this on my js app, I use it :
init(); function init() { var id_fb = "l214.animaux"; while (true) { console.log("je suis ici"); FB.api( '/' + id_fb + '/', 'GET', {"fields":"fan_count"}, function(response) { alert(response.fan_count); } ); } }
But the error is that FB is not defined. Any suggestions ?
