推荐答案

JavaScript中没有像window.id这样的属性。但是，在使用chrome API（chrome.windows.create）时，在回调函数中有这样的属性，但它与javascript本身没有关联（javascript无法识别内部浏览器的标识系统）。

There is no such property like window.id in javascript. However, you have such property in a callback function when using chrome API (chrome.windows.create) but it is not associated with javascript itself (javascript does not recognize internal browser's identification system).

可以使用内部扩展范围，例如 chrome.tabs.getCurrent 方法来检索有关当前选项卡的信息。在回调函数中，您将拥有一个ID。请注意，该ID是可选的，可能不会设置。

Inside extension scope you can use for example chrome.tabs.getCurrent method to retrieve information about current tab. In a callback function you'll have an id. Note that the id is optional and may not be set.
