问题描述
我有两个窗口：父和弹出窗口。显然 parent 引用了 popup 。现在在弹出窗口我有一个函数说
I have two windows: the parent and the popup. Obviously parent has a reference to popup. Now in popup I have a function say
function test() { alert('test'); }
我想在父，类似 popup.test（）; 。有没有办法做到这一点？我确实知道如何做到这一点。只是声明
and I want to call this function in parent, something like popup.test();. Is there a way to do that? I do know how to do that the other way around. Just declaring
window.test = function() { alert('test'); }
并且调用 window.opener.test（）; 在弹出窗口工作正常。但是这在我的情况下不起作用（我认为因为 window.opener 对象是一个引用，但是 window.open 和窗口在弹出窗口中并不真正相关）。任何想法？
and calling window.opener.test(); in popup works fine. However this does not work in my case (I think because the window.opener object is a reference, but window.open and window in popup are not really related). Any ideas?
推荐答案
这实际上取决于您为弹出窗口定义函数的上下文。假设您将函数/数据附加到弹出窗口的窗口对象，您可以从 window.open返回的窗口句柄中访问它。 code>（窗口句柄是 窗口弹出对象）：
It really depends on the context where you defined the function for the popup window. Assuming you attached the functions/data to the window object of the popup window, you can access it from the window handle returned by window.open (the window handle is the window object for the popup):
var w = window.open(somelocation,''); //has a function on `window` called "test"
w.test();
