问题描述

我有选项卡的tabId。如何获取它的窗口对象？

I have the tabId of a tab. How do I get it's window object?

推荐答案

要从tabId获取DOM窗口对象，您应该将内容脚本插入该标签：

To get the DOM window object from a tabId, you should insert a content script in that tab:

chrome.tabs.executeScript(tabId, {code:'var w = window; console.log(w);'});

https://developer.chrome.com/extensions/tabs#method-executeScript

也许你需要与你的背景页面交流：

Perhaps you'll need to comunicate with your background page:

https://developer.chrome。 com / extensions / content_scripts＃主机页面通信
