FB没有定义

Question

我正在尝试重新定向到URL,如果已按下Facebook Like按钮,但它不起作用,并且结果在源视图中出现错误,说"FB未定义"

这是我的重定向代码:

    FB.Event.subscribe('edge.create',
    function(response) {
        location.href = 'censored';
    }
);

这是FB之类的按钮

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

<center><fb:like href="http://www.siriforall.net" send="true" width="450" show_faces="false"></fb:like></center>

有人帮忙吗？我很抱歉.

Answer 1

确保您的FB.Event在fbAsyncInit函数内部,因此您确保已将JS SDK框架加载到浏览器中.还要确保在调用FB.Event之前先调用FB.init().

window.fbAsyncInit=function() {
   // YOUR CODE HERE THAT USES FB.anythin
}
