Chrome扩展程序:2个打开的窗口中的活动选项卡是什么? [英] Chrome Extension: What is the active tab in 2 opened windows?

问题描述

我有一个扩展程序，需要知道活动选项卡上的URL，但是问题是，当我打开第二个Chrome窗口时，有2个活动选项卡，在网站管理员工具中，它没有任何提示我实际上在哪个窗口上. 截屏时，我实际上是在第二个窗口上.

I have an extension that needs to know what URL is on the active tab, but the problem is that when I open a second chrome window there are 2 active tabs, in the webmaster tools it doesn't give me any indication of what window I'm actually on. I was actually on the 2nd window when I took this screenshot.

我正在使用的代码是:

chrome.tabs.query({'active': true}, function (tabs) {
    app.tabInfo = tabs[0];
});

但是好的代码应该是app.tabInfo = tabs[1];，但是我需要知道我需要选择那个代码.那我怎么知道呢?

But the good code would have been app.tabInfo = tabs[1]; but I need to know that I need to pick that one. So how can I know?

谢谢.

推荐答案

进行查询以选择最后一个焦点窗口:

Make your query to select the last focused Window:

chrome.tabs.query({ active: true, lastFocusedWindow: true }, function (tabs) {
  //...
});

注意:最好不要服用currentWindow: true，因为:

Note: Better don't take currentWindow: true because:

当前窗口是包含当前正在执行的代码的窗口.重要的是要意识到这可能与最上面的窗口或聚焦的窗口不同.

The current window is the window that contains the code that is currently executing. It's important to realize that this can be different from the topmost or focused window.
