FB未定义 [英] FB is not defined

问题描述

如果Facebook Like按钮被按下，我正在尝试重定向到一个URL，但它不起作用，并且源视图中的结果发生错误，表示FB未定义

I am trying to redirect to an URL if the Facebook Like button has been pressed, but it doesn't work, and results having an error in the source view saying "FB is not defined"

这是我的重定向代码：

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

这里是FB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，

Anyone help please? I am a noob sorry.

推荐答案

确保您的FB.Event位于fbAsyncInit函数内，以确保JS SDK框架已加载到浏览器中。另外请确保在调用FB.Event之前调用FB.init（）。

Ensure your FB.Event is inside of the fbAsyncInit function so you assured that the JS SDK framework has been loaded into the browser. Also be sure to call FB.init() first before calling FB.Event.

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