Question

我试图让Facebook Javascript SDK客户端身份验证工作，并且它在Firefox中这样做，但它在IE中失败了。在IE 8中，当我单击登录按钮时，根本没有任何事情发生。没有覆盖，没有来自IE的警报，没有任何东西。该代码是由Facebook提供的示例代码，很少有修改方式。

任何人都可以告诉我我可能做错了什么吗？谢谢！

首先：您认为在您的网页中使用两个 <html>元素会有什么好处？删除第一个，这是胡说八道。

在IE 8中，当我点击登录按钮时，根本没有任何事情发生。

IE＆LT; 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此功能添加到旧IE（我没有看到）的库，否则您的代码无法以这种方式工作......并且实际上应该在JS控制台中引发错误。（你甚至懒得去看那里吗？）
