弹出窗口和同一域的另一个窗口之间的跨窗口JS交互 [英] Cross window js interaction between a popup and another window of the same domain

问题描述

我正在尝试从example.com的窗口a打开一个弹出窗口.然后关闭窗口a，然后在同一域(example.com)中打开另一个窗口b.是否可以从窗口b访问窗口a的DOM?如何访问?

I'm trying to open a popup from window a at example.com. then close window a and open another window b at the same domain (example.com). Is it possible to access the DOM of window a from window b and how?

弹出式窗口是通过

从窗口a打开的

The popup is opened from window a by

window.open('http://example.com/blah', 'somename', settings..), 

从窗口b使用不同的URL(如下所示)执行相同的操作

Executing the same from window b with a different url (shown below) works

window.open("http://example.com/blah2", "somename" ...) 

这似乎建议通过窗口名称访问窗口.但是，无论有没有窗口名称，我都无法找到访问弹出窗口DOM的任何方法.我该怎么办?

This seems to suggest windows are accessed by window name. But I could not find any way to access to DOM of the popup with or without the window's name. How would I do this?

推荐答案

尝试类似

var newWind = window.open('http://example.com/blah', 'somename',settings);
if (newWind.opener == null) {
    newWind.opener = window;
}
// here you can access DOM of new window
var newDoc = newWind.document;
