Facebook Send的Javascript事件处理程序

Question

I'm integrating the Facebook Send button to our site and I'm trying to run some javascript as soon as the user sends the page to someone. With the Facebook Like button you can subscribe via javascript to the edge.create event which fires when the user Likes the page. Is there an equivalent for the Facebook Send button? I tested it and the edge.create doesn't catch the Send button.

So basically, is there any javascript event handler for the Facebook Send button?

根据https://developers.facebook.com/docs/reference/plugins/send/，您要查找的事件是“ message.send”

You should be able to add your own listeners by directly subscribing them to the classes prototype.

For example, we use this to reposition the Like/Send menus accordingly once rendered:

        var Like = FB.CLASSES['XFBML.Like'];
        Like.prototype.subscribe('xd.presentEdgeCommentDialog', function(a){

            setTimeout(function(){
              var el = $('#like-btn > span.fb_edge_comment_widget');
                    // console.log(a);
                    // console.log(el);
                    el.css('left', '-200px');
                    el.css('top', '20px');
            }, 500);
        })

The exact events you can subscribe depend on the class. You'll need to research this by looking to the JS SDK and then backtracking which events are being fired.

Good luck.

Hmm, have you tried to add a function that looks for the send button and adds your own click listener to it when it gets added?

You won't be able to get any information like response.session, but you can tally how many people click the button.

I can see why they didn't include anything to subscribe to with FB.event.subscribe. When they like your page, connect elements on your page are populated with their information when the page reloads (you may reload the page in your method that gets fired). They can send your page to someone without liking you.
