问题描述
我注意到，在使用Google Mail的Google Chat功能时，您可以在其自己的窗口中弹出聊天窗口。然后，当我关闭Google Mail窗口时，它警告说，如果我继续并显示窗口列表，则其他窗口也将被关闭。这是如何完成的？是否有可能跟踪你调用的窗口是否已关闭？
I noticed when using the Google Chat feature from your Google Mail that you can pop out a chat into its' own window. Then when I went to close the Google Mail window it warned that other windows would also be closed if I continued and then showed a list of the windows. How is this done? Is it possible to track whether a window you invoked has been closed?
推荐答案
是的，当你在JavaScript中执行window.open ，你可以将它设置为一个var：
Yes, when you do a window.open in JavaScript, you can set it to a var like:
myWindow = window.open(...)
然后，您可以将事件绑定到该窗口，如：
Then you could bind events to that window like:
myWindow.onUnload = funcWindowClosed;
您可以通过将多个弹出窗口放入数组中来跟踪多个弹出窗口。
You could keep track of multiple pop-up windows by putting them into an array.
您也可以使用以下方式在子窗口（弹出窗口）中调用父窗口中的JavaScript函数：
You can also call JavaScript functions in the parent window by the child (pop-up) window using:
window.opener
