推荐答案

你想得到的结果从代码是不可能的。让我们调用你执行javascript window 1 的窗口，然后打开一个全新的窗口 window 2 。现在，窗口2 既没有引用你的js代码，也没有 onload 事件。 窗口2 的onload事件在窗口1 实例中触发。因此，您将在窗口1获取控制台日志实例不在窗口2 。

The result you want to get from the code is not possible. Let's call the window where you are executing javascript window 1 and you are opening a fresh new window window 2. Now, window 2 neither has reference of your js code nor has the onload event. onload event of window 2 is firing at window 1 instance. So, you are getting the console log at window 1 instance not in window 2.
