Facebook“喜欢"按钮回调 [英] Facebook "Like" button callback

问题描述

我对实现 facebook 的赞"按钮很感兴趣，但我想知道什么用户点击了这个按钮，以便我可以从中获得一些有用的信息.从我读到的内容来看，Facebook 让我们对谁在点击什么一无所知.任何人都知道我如何跟踪哪个用户点击了特定产品的喜欢按钮?

I am interested in implementing the facebook "Like" button, but I would like to know what user is clicking on this button so I can get some useful information from this. From what I have read, facebook is leaving us in the dark on who is clicking on what. ANyone have an idea on how I could track which user clicked on a like button for a particular product?

更新:点赞按钮由 ​​facebook 通过 iFrame 或 xFBML 呈现.这就是为什么很难跟踪谁点击了什么，或者嵌入一个 onclick 事件等等.

UPDATE: The like button is rendered by facebook either through an iFrame, or through xFBML. This is why it is difficult to track who clicks on what, or embed an onclick event, etc..

推荐答案

<script>
  FB.Event.subscribe('edge.create', function(href, widget) {
    alert('You just liked the page!');
  });
