Question

Facebook SDK window.fbAsyncInit没有在localhost上触发？上周工作正常。

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
        console.log("hey");
        // init the FB JS SDK
        FB.init({
          appId      : '***************', // App ID from the App Dashboard
          channelUrl : '//localhost/channel.html', // Channel File 
          status     : true, // check the login status upon init?
          cookie     : true, // set sessions 
          xfbml      : true  // parse XFBML tags on this page?
        });
}
  // Load the SDK's source Asynchronously
  // Note that the debug version is being actively developed and might 
  // contain some type checks that are overly strict. 
  // Please report such bugs using the bugs tool.
  (function(d, debug){
     var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
     if (d.getElementById(id)) {return;}
     js = d.createElement('script'); js.id = id; js.async = true;
     js.src = "//connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
     ref.parentNode.insertBefore(js, ref);
   }(document, /*debug*/ true));
</script>

“hey”在加载页面时不会触发

另外我注意到当我在“Fb.init”中注释掉频道网址时，却添加了：

<script src="//connect.facebook.net/en_US/all.js"></script>

在文件的标题内，“嘿”会在首次加载页面时触发，但不会在后续尝试时触发

更明确。这就是我的控制台中的错误：

Uncaught SyntaxError: Unexpected token ( connect.facebook.net/en_US/all/debug.js:9237

您错过了加载FB.init（）下面的SDK。

(function(d, debug){
 var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
 if (d.getElementById(id)) {return;}
 js = d.createElement('script'); js.id = id; js.async = true;
 js.src = "//connect.facebook.net/en_US/all" + (debug ? "/debug" : "") + ".js";
 ref.parentNode.insertBefore(js, ref);
}(document, /*debug*/ false));`

并确保在App setting page中设置App Domains。

目前在all.js的调试版本的呈现中存在一个错误 - 导致您的代码无法正确执行。这将很快得到解决。
