Menu
I'm trying to subscribe to the Like button click. Here's the code I have:
<body>
<!-- Facebook Like Button with your App ID -->
<div id="fb-root"></div>
<script>(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/all.js#xfbml=1&appId=349467237487892";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
FB.Event.subscribe('edge.create',
function(response) {
alert('You liked the URL: ' + response);
}
);
The Like button appears and works ok but I don't get the alert when it's clicked. Does anyone see the problem?
Thanks for your help.

You need to attach the event after the JS SDK has had a chance to load. Use fbAsyncInit to do this.
window.fbAsyncInit = function() {
FB.Event.subscribe('edge.create', function(response) {
alert('You liked the URL: ' + response);
});
};
As far as I can tell from the api you need to subscribe to the edge.create event - example from api documentation.
FB.Event.subscribe('edge.create',
function(response) {
alert('You liked the URL: ' + response);
}
);
You can read more about FB event subscription here.
