 我们试图避免使用ctrl-n javascript钩子 
 
 
 算了吧。 虽然理论上你可以尝试使用Control键修饰符捕获'​​n'的按键事件，但是有很多其他方法可以打开一个可能更有可能被使用的新窗口或标签，你将无法使用去抓。 文件 - >新窗口/选项卡，中键单击或按住Shift键单击链接，中键单击后退/前进按钮，右键单击 - 打开新窗口，在新选项卡中打开书签，双击浏览器图标... 
 
 
 
 用户已经过身份验证，我们会大量使用会话。 
 
 
 这本身不应该是一个问题。 我猜你的意思是你的应用程序在会话中倾倒了不应该有的各种特定于页面的数据，现在当你打开多个窗口时，你会发现应用程序中断了吗？ 好吧，怜悯和愉快的改写。 
 
 与此同时，您可以做的就是告诉用户“请不要尝试在同一个应用程序上打开两个浏览器窗口”。 有一些方法可以让你在一个页面上发现JavaScript同时注意到JavaScript在同一个域中的另一个页面上运行，通常涉及使用document.cookie作为页面间通信管道。 但那也有点脆弱。 

 
 
We were trying to avoid ctrl-n javascript hooks
 
 
Forget it. Whilst you could in theory try to catch keypress events for ‘n’ with the Control key modifier, there are any number of other ways to open a new window or tab which may be more likely to be used, and you won't be able to catch. File->New Window/Tab, middle click or shift-click link, middle click back/forward buttons, right-click-open-in-new-window, open bookmark in new tab, double-click browser icon...
 
 
 
The user is already authenticated and we make heavy use of sessions.
 
 
That shouldn't be a problem in itself. I guess what you mean is that your application is dumping all sorts of page-specific data in the session that it shouldn't have, and now you find the application breaks when you have more than one window open on it? Well, commiserations and happy rewriting.
 
In the meantime about all you can do is tell the user “please don't try to open two browser windows on the same application”. There are potential ways you can make JavaScript on one page notice that JavaScript is running on another page in the same domain at the same time, generally involving using document.cookie as a inter-page communications conduit. But that's also a bit fragile.
