在Chrome扩展程序中，确定用户是否单击了浏览器的“后退”或“前进”按钮
[英]In Chrome extension determine if the user clicked the browser's Back or Forward button
问题描述
How can I know whether the user clicked back/forward button in Chrome from within my Chrome Extension? 
如何知道用户是否在我的Chrome扩展程序中点击了Chrome中的后退/前进按钮？
The only API that could give me any such info is the chrome.webNavigation.onCommitted which in the case of when the back or forward button are clicked, sends a NavigationQualifier containing the string 'forward_back' . 可以给我任何此类信息的唯一API是chrome.webNavigation.onCommitted ，在单击后退或前进按钮的情况下，发送包含字符串'forward_back'的NavigationQualifier 。 The problem here is that I'm not able to distinguish between the two buttons. 这里的问题是我无法区分这两个按钮。

You could use the tabs API's onUpdated event if that's good enough for you. 您可以使用tabs API的onUpdated事件，如果这对您来说足够好的话。
Alternatively, you could use the HTML5 history API and register a window.onpopstate handler. 或者，您可以使用HTML5历史记录API并注册window.onpopstate处理程序。 Do that from within a content script that runs before the page. 从在页面之前运行的内容脚本中执行此操作。
