我希望在我的firefox addon .i上运行特定函数时关注firefox创建一个.vbs文件，该文件可以将firefox [置于顶部]然后使用{{执行该exe来执行1}}。喜欢这个
nsIProcess它运行正常。但由于某种原因，我想直接从插件代码集中Firefox，而无需其他应用程序的帮助。我阅读了firefox file.initWithPath("C:\\Users\\madhawax\\Documents\\focusFirefox.vbs");
var process = Cc["@mozilla.org/process/util;1"].createInstance(Ci.nsIProcess);
process.init(file);
process.run(false, args, args.length);
api，但我无论如何都找不到关注窗口。我问的是如何从插件代码中集中浏览器。
编辑..
这是我用来关注firefox的代码。

这些解决方案使用js-ctypes winapi。这是一个Windows解决方案。 OSX和Linux没有这个问题，很容易将重点放在那里。
如果我们只能执行SetForegroundWindow winapi方法会很容易，但调用此方法的过程必须具有用户关注点。如果没有，那么它什么都不做，所以这里有强迫它的方法：
此方法执行以下操作：
SetForegroundWindow将起作用，因此它会执行此操作并退出SetForegroundWindow并退出AttachThreadInput将firefox的线程附加到当前前台窗口的线程中SetForegroundWindow，因为它现在可以正常工作SetForegroundWindow调用，它将失败，因为它通常应该我想不出AttachThreadInput会失败的原因，但如果确实如此，那就是这种方法中唯一不可靠的部分。如果有人知道为什么会失败那么请分享一个解决方案，以解决失败的原因。但是，我将下面的SetCursorPos方法作为紧急回退。

这是一个使用js-ctypes的解决方案，仅适用于Windows操作系统，它执行以下操作：
它有一个问题，SendInput中同义词鼠标点击的x和y坐标没有被尊重，这就是为什么我必须使用SetCursorPos，在未来的修订中，我想解决这个问题所以它不使用SetCursorPos因为移动用户鼠标对用户来说很烦人，但是这个好处远远超过了轻微的烦恼，因为它非常重要的是让窗口集中，我暂时接受这个{{1因为我做了“在偷窃之前恢复光标位置”，所以这里是：

什么都不做。
经过测试，即使另一个窗口设置为“始终在顶部”，这也有效，但由于另一个窗口始终位于顶部，因此在关注此窗口后，这将是最顶层的窗口。
