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!
答案 0 :(得分:1)
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?)
