我试图让 Facebook Javascript SDK 客户端身份验证正常工作，它在 Firefox 中这样做，但在 IE 中失败得很惨。在 IE 8 中，当我单击登录按钮时，什么也没有发生。没有覆盖，没有来自 IE 的警报，什么都没有。该代码是 Facebook 提供的示例代码，几乎没有修改。

      // Load the SDK Asynchronously
      (function(d){
         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.js";
         ref.parentNode.insertBefore(js, ref);
       }(document));

      // Init the SDK upon load
      window.fbAsyncInit = function() {
        FB.init({
          appId      : 'xxxxxxxxxxxxxxx', // App ID
          channelUrl : '//thejspot.ws/channel.html', // Path to your Channel File
          status     : true, // check login status

          xfbml      : true  // parse XFBML
        });

        // listen for and handle auth.statusChange events
        FB.Event.subscribe('auth.statusChange', function(response) {
          if (response.authResponse) {
            // user has auth'd your app and is logged into Facebook
            FB.api('/me', function(me){
              if (me.name) {
                document.getElementById('auth-displayname').innerHTML = me.name;
                oFormObject = document.forms['ri_form'];
                oFormObject.elements['full_name'].value = me.name;

            })
            document.getElementById('auth-loggedout').style.display = 'none';
            document.getElementById('auth-loggedin').style.display = 'block';
          } else {
            // user has not auth'd your app, or is not logged into Facebook
            document.getElementById('auth-loggedout').style.display = 'block';
            document.getElementById('auth-loggedin').style.display = 'none';
          }
        });

        // respond to clicks on the login and logout links
        document.getElementById('auth-loginlink').addEventListener('click', function(){
          FB.login(function(response) {}, {scope: 'email'});

谁能告诉我我可能做错了什么？谢谢！

首先：是什么让您认为在您的页面中包含两个 <html>元素会有益......？删除第一个，这是胡说八道。

在 IE 8 中，当我单击登录按钮时，什么也没有发生。

IE < 9 不支持addEventListener将事件处理程序绑定到 DOM 元素。因此，除非您还嵌入了一些将这种功能添加到旧 IE 的库（我没有看到任何内容），否则您的代码不能以这种方式工作......并且实际上应该在 JS 控制台中引发错误。（你有没有费心去看那里？）
