视窗
使用chrome.windows模块与浏览器视窗进行交互。 你可以使用这个模块在浏览器中创建、修改和重新排列视窗。
清单
要使用视窗 API,你必须在manifest.json声明"tabs"的权限 。(不,这不是一个错字 - 窗口和标签模块的互动如此密切,我们决定它们共享一个权限。)例如:
{ "name": "My extension", ... "permissions": ["tabs"], ... }
当前视窗
很多扩展系统的功能有一个可选的windowId参数,其默认值为当前视窗。
当前视窗是指包含当前正在执行的代码的视窗。重要的是要认识到,它可以跟最顶层或有焦点的视窗不一样。
例如,假设一个扩展从一个单一的HTML文件中创建了一些标签或视窗,而这个HTML文件包含一个chrome.tabs.getSelected的调用 。 当前视窗是指那个包含了发起调用的页面的视窗,不管它是不是最顶层视窗。
在背景页这个例子中 ,当前视窗就是最后一个活动视窗。在某些情况下,背景页可能没有当前视窗。
范例
你可以在examples/api/windows 目录下找到一些使用windows模块的简单范例。另外一个范例是在tabs_api.html文件中的检查器范例。 对于其他的例子和查看源代码的帮助,参见示例 。
