Facebook login Javascript SDK only running in first page

Hi there,

I have included Facebook login Javascript SDK to create a social login button and display participants' Facebook user picture in Qualtrics. One problem I am facing is that displaying the user picture works fine the very first time I want to show it, but not anymore on follow up pages (i.e. after clicking the next button). The same applies to the social login button, but I only need that to show that once anyway, so that's not really a problem. I've tried simply copying the Javascript code to the question where I also want to show the user picture, as well as adding it to the header in the look&feel, but I cannot get it to work. It works fine for the first question I use it in (regardless of where in the survey it is), but not for any follow-up questions. Any help would be very much appreciated!

Thanks!

Here's the code I used:

Qualtrics.SurveyEngine.addOnload(function()
{
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
getInfo();
} else {
// The person is not logged into your app or we are unable to tell.
document.getElementById('status').innerHTML = "<span style='color: #333333; font-size: 16px;'>Facebook account (please connect your account)</span>";
}
}

// 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 : '875253029346318',
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 getInfo() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', 'GET', {fields: 'first_name,last_name,name,id,picture.width(100).height(100)'}, function(response) {
document.getElementById('status').innerHTML = "<img src='" + response.picture.data.url + "'>";
});
}

});
