Facebook Share Dialog Opening in iFrame inconsistent

Question

I have implemented Facebook Share dialog with javascript and I am having consistency issues.

I have a button to open the dialog and when I do so from the page it automatically appears in an iframe on the page which is great! Exactly what I want.

Now here's the issue, I have another page that redirects to this exact same page and it is set to call the exact same function for the facebook share dialog if a get variable is set. It calls it but now it opens in a new window instead of in an iframe and I have no idea why. I will literally close the window and click on the button and it will open it perfectly in an iframe.

$(document).ready(function() {
        window.fbAsyncInit = function() {
            FB.init({
                appId            : '######',
                autoLogAppEvents : true,
                xfbml            : true,
                version          : 'v3.2'
            });

            @if(isset($_GET['share']))
                facebook_share();
            @endif
        };

        (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/all.js";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));

        $('.fb-share').click(function() {
            facebook_share();
        });
    });

    function facebook_share(){
        FB.ui({
            method: 'share',
            mobile_iframe: true,
            href: '######',
        }, function(response){
            if (response && !response.error_message) {
                success.style.display = "block";
            } else {
                error.style.display = "block";
            }
        });
    }

Answer 1

Figured this out myself, simply setting a timeout before making the call to the function caused it to act the same way. Everything must not have been fully loaded upon the original call.

setTimeout(facebook_share, 3000);
