检测跨域弹出窗口何时关闭 [英] Detecting when a Cross-Domain Popup Window Closes

问题描述

我有一个生活在domainA.com上的javascript应用程序。为了验证用户身份并设置cookie，它会在domainB.com上打开一个弹出窗口。 （这类似于Twitter的@anywhere）。

如何检测domainB.com上的弹出窗口何时关闭并调用在domainA.com上打开它的javascript中的函数？

我尝试了各种方法，如window.opener，window.unload等，但遇到跨域限制。

I have a javascript application that lives on say domainA.com. In order to authenticate a user and set cookies, it opens a popup window on domainB.com. (this is similar to Twitter's @anywhere).

How do detect when the popup on domainB.com closes and call a function in the javascript that opened it on domainA.com?

I've tried various methods like window.opener, window.unload, etc, but run into cross domain limitations.

解决方案

window.postMessage will help you on browsers that support it... https://developer.mozilla.org/en/DOM/window.postMessage
